Philosophy of Cosmology

The causal principle of the Kalām cosmological argument—Everything that begins to exist has a cause—remains controversial. One common objection is that while the principle may apply to things within the universe, it does not apply to the universe itself. Here, I argue that if the universe began uncaused, then there is an extremely high probability that the universe began just moments ago with the appearance of age. However, I further argue that the general agreement of independent estimates for the universe’s (...) age provides powerful empirical evidence that if the universe began to exist, then the universe has a cause.

Forces mediate the differences between local amounts of energy in the universe at all scale sizes and determine the direction of the motion of energy configurations. But forces are not always easy to identify and to describe in a com­prehensive explan­atory model.

ليس بالتفكير نخلق العوالم، بل بفهم العالم نتعلم التفكير. "الرؤية الكونية" هو مصطلح يجب أن يعني مجموعة من الأسس التي تنبثق منها فهم منهجي للكون، ومكوناته كالحياة، والعالم الذي نعيش فيه، والطبيعة، والظواهر البشرية، وعلاقاتها. إنه، بالتالي، مجال من الفلسفة التحليلية يغذيه العلوم، وهدفه هو هذا المعرفة المجمعة والمستدامة معرفيًا عن كل ما نحن عليه ونحتويه، وما يحيط بنا، وما يرتبط بنا بأي شكل من الأشكال. إنه شيء قديم قدم الفكر البشري، وبالإضافة إلى استخدام عناصر من علم الكونيات العلمي، فإنه (...) يشمل كل شيء في الفلسفة والعلوم الذي يشير إلى الكون والحياة. الرؤية الكونية ليست مجموعة من الأفكار والفرضيات والافتراضات بل هي نظام قائم على الملاحظة والتحليل والدليل والتوضيح. لا تهدف أي رؤية كونية إلى التعريف أو التأسيس أو الاقتراح بل فقط إلى الفهم والتحليل والتفسير. كل منا يبني وينقل رؤيته الكونية طوال حياته، دون إنشاء أشكال، كخلفية لتفكيرنا وسلوكنا. لغويًا، قد يشتق مصطلح "الرؤية الكونية" من الألمانية، ويعادل مفهوم "Weltanschauung"، كما استخدمه عدة فلاسفة. ومع ذلك، فإن هذه العلاقة اللغوية غير قابلة للتطبيق لأنها تتعارض مع ما نقترحه كرؤية كونية. تشير هذه الكلمة الألمانية إلى رؤية واقعية قبل منطقية أو أولية، ذات سياق حدسي وبعيدة عن المعرفة النقدية التي لم تكن موجودة بعد في وقت صياغتها. بلا شك، تحتوي الرؤى الكونية، بالمعنى الذي نفهمها، وتستخدم هذه العناصر الأولية أو قبل المنطقية التي تشمل التاريخ واللاوعي الجماعي وكل النماذج التي نحملها. ومع ذلك، في المفهوم الذي نطبقه هنا، تتجاوز الرؤية الكونية هذا المحتوى بكثير، أولاً من خلال إخضاعه باستمرار للتفكير النقدي الحالي، وأخيرًا من خلال جعل التجربة التحليلية (وليس التفكير نفسه أو الحدس) كونها الفعلي. يعرض أنطونيو لوبيس اتساع هذا المحتوى: "الرؤى الكونية ليست نتاج الفكر. لا تنبع من الرغبة البسيطة في المعرفة. إن استيعاب الواقع هو لحظة مهمة في تكوينها، ولكن، مع ذلك، هي واحدة فقط. إنها تأتي من السلوك الحيوي، ومن تجربة تقييم الحياة، ومن هيكل كليتنا النفسية. إن رفع الحياة إلى الوعي في معرفة الواقع، وفي التقييم، وفي الواقع الإرادي هو العمل البطيء والشاق الذي قامت به الإنسانية في تطوير مفاهيم الحياة. (ديلتاي، 1992 [1911]: 120)"(1) في هذا العمل، نسعى إلى تحديد رؤية كونية تستند إلى الحقائق التي تقدمها العلوم اليوم. لا نقترح، في أي وقت، أن نقوم بالعلم؛ أو نظري الفلسفة، لكننا سنسعى دائمًا لأن ندعم بها أو، على الأقل، نحتمي بها من التشوهات المعرفية التي نحملها عادة.

हम सोच कर दुनिया नहीं बनाते। दुनिया को समझ कर हम सोचना सीखते हैं। कॉस्मोविज़न एक ऐसा शब्द है जिसका मतलब नींव का एक समूह होना चाहिए जिससे ब्रह्मांड, जीवन के रूप में इसके घटकों, जिस दुनिया में हम रहते हैं, प्रकृति, मानवीय घटनाओं और उनके संबंधों की एक व्यवस्थित समझ उभरती है। इसलिए, यह विज्ञान द्वारा पोषित विश्लेषणात्मक दर्शन का एक क्षेत्र है, जिसका उद्देश्य हम जो हैं और जो हमारे चारों ओर है, और जो किसी भी तरह से (...) हमसे संबंधित है, उसके बारे में यह एकत्रित और ज्ञानमीमांसीय रूप से स्थायी ज्ञान है। यह मानव विचार जितना ही पुराना है, और वैज्ञानिक ब्रह्मांड विज्ञान के तत्वों का उपयोग करने के अलावा, यह दर्शन और विज्ञान में ब्रह्मांड और जीवन को संदर्भित करने वाली हर चीज को शामिल करता है। एक कॉस्मोविज़न विचारों, परिकल्पनाओं और मान्यताओं का एक समूह नहीं है, बल्कि अवलोकन, विश्लेषण, साक्ष्य और प्रदर्शन पर आधारित एक प्रणाली है। कोई भी कॉस्मोविज़न परिभाषित करने, स्थापित करने या प्रस्तावित करने का इरादा नहीं रखता है, बल्कि केवल समझने, विश्लेषण करने और व्याख्या करने का इरादा रखता है। हममें से प्रत्येक व्यक्ति अपने सोच और व्यवहार के लिए पृष्ठभूमि के रूप में, रूपों को स्थापित किए बिना, जीवन भर अपने कॉस्मोविज़न का निर्माण और परिवहन करता है। भाषाई रूप से, "कॉस्मोविज़न" शब्द जर्मन से लिया गया है, जो कई दार्शनिकों द्वारा इस्तेमाल किए गए "वेल्टनशाउंग" की अवधारणा के बराबर है। हालाँकि, यह भाषाई संबंध लागू नहीं होता है क्योंकि यह हमारे द्वारा प्रस्तावित ब्रह्मांड-दृष्टि के विपरीत है। यह जर्मन शब्द वास्तविकता के एक पूर्व-तार्किक या प्रोटो-प्रयोगात्मक दृष्टिकोण को संदर्भित करता है, जिसमें एक सहज संदर्भ होता है और आलोचनात्मक ज्ञान से बहुत दूर होता है जो इसके निर्माण के समय भी अस्तित्व में नहीं था। निस्संदेह, ब्रह्मांड-दृष्टि, जिस अर्थ में हम उन्हें समझते हैं, इन प्रोटो-प्रयोगात्मक या पूर्व-तार्किक तत्वों को समाहित करता है और उनका उपयोग करता है जिसमें इतिहास, सामूहिक अचेतन और हमारे द्वारा धारण किए जाने वाले सभी मूलरूप शामिल हैं। हालाँकि, जिस अवधारणा को हम यहाँ लागू करते हैं, उसमें ब्रह्मांड-दृष्टि इस सामग्री से बहुत आगे निकल जाती है, सबसे पहले इसे लगातार वर्तमान आलोचनात्मक सोच के अधीन करके, और अंत में विश्लेषणात्मक अनुभव (और न कि विचार या अंतर्ज्ञान) को अपना वास्तविक ब्रह्मांड बनाकर। एंटोनियो लोपेस इस विषय-वस्तु की व्यापकता को उजागर करते हैं: "ब्रह्मांडीय दर्शन विचार की उपज नहीं हैं। वे जानने की सरल इच्छा से उत्पन्न नहीं होते हैं। वास्तविकता की समझ इसकी संरचना में एक महत्वपूर्ण क्षण है, लेकिन फिर भी, यह केवल एक है। यह जीवन के मूल्यांकन के अनुभव से, और हमारी मानसिक समग्रता की संरचना से, जीवन को वास्तविकता के ज्ञान में, मूल्यांकन में, और इच्छाधारी वास्तविकता में चेतना तक ऊपर उठाना वह धीमा और कठिन कार्य है जो मानवता ने जीवन की अवधारणाओं के विकास में किया है।" -/- .

● Mucho más relevante que la complejidad o simplicidad de un método de medir las casas es si dicha división se mantiene fiel a la física del cielo (i.e. si tiene sentido alguno). ● Dado que la astrología no goza de una institución central que decida qué es válido y qué no, consideramos que lo mínimo que pueden hacer los astrólogos es respetar las verdades confirmadas por la ciencia. La física enseña que no podemos separar el tiempo del espacio o (...) el espacio del tiempo, pues sostienen una relación ininterrumpida o indisoluble que llamamos continuo , un plano constituido de cuatro dimensiones (i.e. las tres del espacio aunadas a la única del tiempo) denominado espaciotiempo, y que el tiempo no es absoluto sino relativo (dependiente de los marcos de referencia). ● La astrología (que no es horoscopismo sino una de las consecuencias de la física) apela a diferentes métodos de medir las regiones astrográficas (i.e. casas) y los ha clasificado entre métodos espaciales y métodos temporales (según cuál de los dos conceptos decide la subdivisión del arco diurno) , pero esta clasificación resulta impertinente ante la realidad que nos gobierna. Uno que puede ser confirmado compatible con nuestra realidad debe ser empleado en todo momento para todo tipo de astrografía, es decir, uno verdadera o esencialmente basado en el espaciotiempo sin presentar, a la misma vez, ninguno de los errores característicos de otros sistemas de casas . Veremos que solo uno de ellos es compatible con la relatividad, pues mientras los demás nos harían hacer creer que el tiempo es absoluto, el método Placidus de medición de las casas nos enseña que es relativo. ● La diferencia estriba en la capacidad de un método para reconocer los tiempos ascensionales de no solo los doce segmentos de nuestra eclíptica en distintas latitudes, sino también de cada grado de dicha circunferencia simultánea e ininterrumpidamente, es decir, temporalmente simultánea y espacialmente ininterrumpida durante sus trayectorias desde el horizonte (ASC) hasta el medio cielo (MC). Hemos concluido, con base en el análisis de las cúspides de casas, que solamente la fórmula placidiana puede cumplir la promesa antes referida, es decir, hacer posible medir las duraciones del tiempo bajo tales condiciones. ● Mientras las mediciones del tiempo Alcabitius y Koch asignan velocidades (i.e. tiempos de ascensión oblicua) ficticias a todos los grados contenidos entre el horizonte (ASC) y el medio cielo (MC), Placidus se ocupa de medir las velocidades o los tiempos verdaderos de todos. La medida más newtoniana de todos los métodos de división de casas, Regiomontanus, a su turno, se aferra al espacio a expensas del tiempo, razón por la cual no puede reflejar las verdaderas posiciones de los planetas en el espaciotiempo (ignora la relación del espacio con el tiempo). ● Durante el proceso demostrativo, aprovechamos la ocasión para señalar que la velocidad (relatividad especial) y la gravedad (relatividad general) no constituyen las únicas (dos) expresiones principales de la dilatación del tiempo. La inclinación o basculación de los marcos de referencia (i.e. la inclinación del eje de la Tierra con relación al plano de la eclíptica, si bien la velocidad sigue siendo una variable, mientras la gravedad, a su vez, una posibilidad que exploraremos en los apéndices) constituye una tercera expresión. ● Animamos a todo físico y/o astrónomo a corroborar nuestras observaciones con sus propias herramientas. Por nuestra parte, hemos empleado el software astrológico/astronómico Solar Fire Gold, si bien las astrografías o mapas provienen del software astrológico/astronómico Janus. (shrink)

This article explores the divergent views between and the possible consequences of various cosmocentric understandings including that of Astronism and the geocentric/biocentric concerns of contemporary pagan spirituality. These contrasting religious positions are discussed using the sociological measuring tool of the ideal-type. In actuality, no religion conforms fully to its ideal conception. Instead, the device is employed as an analytic. Vis-à-vis humanity itself, however, the question turns to whether we attempt ultimately to escape our earthly confines or rectify and restore our (...) terrestrial conditions. (shrink)

This paper, which is a homage to the life and work of Stephen Gaukroger, explores competing receptions of Spencer’s programmatic synthetic philosophy. In so doing, I show how T.H Huxley and C.S. Peirce reconfigured a familiar, long-standing debate about cosmogeny and cosmology in the early modern period.

Within we prove Time is the potential of omnipotence. It also demonstrates that when we try to control it from a philosophical point of view it obscures us from Serendipity and access to the splendor of the perfect balance between Freewill and the Will of THE Universe as constrained by the Laws of the Universe. It creates Math or the language of the Creator. It is in fact Time that makes everything from nothing while the net sum of time remains (...) constant at zero. We also examine what Essence existed before time to calibrate C and ???????????????? to provide the harmonics for use in OUR Universe. (shrink)

If an asymmetry in time does not arise from the fundamental dynamical laws of physics, it may be found in special boundary conditions. The argument normally goes that since thermodynamic entropy in the past is lower than in the future according to the Second Law of Thermodynamics, then tracing this back to the time around the Big Bang means the universe must have started off in a state of very low thermodynamic entropy: the Thermodynamic Past Hypothesis. In this paper, we (...) consider another boundary condition that plays a similar role, but for the decoherent arrow of time, i.e. the subsystems of the universe are more mixed in the future than in the past. According to what we call the Entanglement Past Hypothesis, the initial quantum state of the universe had very low entanglement entropy. We clarify the content of the Entanglement Past Hypothesis, compare it with the Thermodynamic Past Hypothesis, and identify some challenges and open questions for future research. (shrink)

Energy politics lie at the heart of human activity. In a time of ecological and energy crises, it is fundamental to realise that our reality systems are always open to change and that, in order to respond to the challenges of a changing energy landscape, we must explore the full possibilities of technology in a radical way. This analysis aims to consider the ethical implications of energy and technology, presenting an urgent case for cosmotechnical pluralism, that is the diversification of (...) world-views, knowledges, technologies in the realm of global politics. To reconstruct the world and its politics around the existence of several ways of navigating and conceiving it, literally leads to a change in reality. The notion of cosmotechnics will present a way of conceiving of the cosmic, epistemic and technic order as interconnected: in this spirit, this exploration will travel through the prisms of cosmology, epistemology, morality, to subsequently enter into the room where energy policies are created. By employing this tripartite framework, policy directions will be suggested on the path towards energy justice in the hope of shining some light on what moral practices of policy-making in the field of energy politics could look like.

We obtain that Universe space has to be flat, but also, at the same time, it has to be finite, homogeneous (on global scale) and isotropic. So rays of light can be observed moving along parallel trajectories in an expanding finite hypersphere. We show this implies an accelerated expansion of the Universe. Considering the energy conservation problem, also we argue about the necessity of matter-antimatter asymmetry.

Ang Diyos ay hindi naglalaro ng dado", inulit ni Einstein mula sa taas ng kanyang determinismo, ngunit sa katunayan ang kosmos ay naghahagis ng mga buto nito nang sadyang mapagpasya: ang mga dado nito ay laruin. Hindi sa pag-iisip na tayo ay lumikha ng mga mundo. Sa pamamagitan ng pag-unawa sa mundo natututo tayong mag-isip. Ang Cosmovision ay isang termino na dapat ay nangangahulugang isang hanay ng mga pundasyon kung saan lumalabas ang isang sistematikong pag-unawa sa Uniberso, ang mga bahagi (...) nito bilang buhay, ang mundong ating ginagalawan, kalikasan, mga phenomena ng tao, at ang kanilang mga relasyon. Ito ay, samakatuwid, isang larangan ng analytical na pilosopiya na pinapakain ng mga agham, na ang layunin ay ang pinagsama-samang at epistemologically sustainable na kaalaman tungkol sa lahat ng kung ano tayo at nilalaman, na nakapaligid sa atin, at nauugnay sa atin sa anumang paraan. Ito ay isang bagay na kasingtanda ng pag-iisip ng tao, at, bilang karagdagan sa paggamit ng mga elemento ng siyentipikong kosmolohiya, sinasaklaw nito ang lahat ng bagay sa pilosopiya at agham na tumutukoy sa uniberso at buhay. Ang cosmovision ay hindi isang set ng mga ideya, hypotheses, at assumptions kundi isang sistemang batay sa obserbasyon, pagsusuri, ebidensya, at pagpapakita. Walang cosmovision na naglalayong tukuyin, itatag, o imungkahi ngunit para lamang maunawaan, suriin, at bigyang-kahulugan. Bawat isa sa atin ay nagtatayo at naghahatid ng kanyang kosmobisyon sa buong buhay, nang hindi nagtatatag ng mga anyo, bilang isang background para sa ating pag-iisip at pag-uugali. Sa lingguwistika, ang terminong "cosmovision" ay magmumula sa Aleman, katumbas ng konsepto ng "Weltanschauung," na ginamit ng ilang mga pilosopo. Gayunpaman, ang relasyong pangwika na ito ay hindi naaangkop dahil sumasalungat ito sa aming iminumungkahi bilang isang cosmovision. Ang salitang Aleman na ito ay tumutukoy sa isang pre-logical o proto- experimental na pananaw ng realidad, na may intuitive na konteksto at malayo sa kritikal na kaalaman na wala pa rin sa oras ng pagbabalangkas nito. Walang alinlangan, ang mga cosmovision, sa diwa kung saan natin nauunawaan ang mga ito, ay nagtataglay at gumagamit ng mga proto-experimental o pre-logical na elementong ito na kinabibilangan ng kasaysayan, ang sama-samang walang malay, at lahat ng mga archetype na dala natin. Gayunpaman, sa konseptong inilalapat natin dito, ang cosmovision ay higit na lumalampas sa nilalamang ito, una sa pamamagitan ng patuloy na pagsusumite nito upang ipakita ang kritikal na pag-iisip, at sa wakas sa pamamagitan ng paggawa ng analitikong karanasan (at hindi ang kaisipan mismo o intuwisyon) ang aktwal nitong uniberso. Inilantad ni António Lopes ang lawak ng nilalamang ito: "Ang mga cosmovision ay hindi produkto ng pag-iisip. Hindi sila nagmumula sa simpleng pagnanais na malaman. Ang pagkaunawa sa katotohanan ay isang mahalagang sandali sa pagsasaayos nito, ngunit, gayunpaman, ito ay isa lamang. Ito ay nagmumula sa mahahalagang pag-uugali, mula sa karanasan ng pagsusuri sa buhay, at mula sa istruktura ng ating saykiko na kabuuan Ang pagtaas ng buhay sa kamalayan sa kaalaman sa realidad, sa pagpapahalaga, at sa kusang katotohanan ay ang mabagal at mahirap na gawain. na ginawa ng sangkatauhan sa pagbuo ng mga konsepto ng buhay (W. Dilthey, 1992 [1911]: 120). Sa gawaing ito, hinahangad nating balangkasin ang isang kosmobisyon batay sa mga realidad na inaalok natin ngayon hindi nagmumungkahi, sa anumang oras, na gumawa ng agham; o magteorya ng pilosopiya, ngunit lagi nating hahanapin na suportahan sila o, hindi bababa sa, protektahan nila mula sa mga pang-unawang distorsyon na karaniwan nating dala.

Cosmovisione è un termine che dovrebbe significare un insieme di fondamenti da cui emerge una comprensione sistemica dell'Universo, delle sue componenti come la vita, il mondo in cui viviamo, la natura, il fenomeno umano e le sue relazioni. Si tratta, quindi, di un campo della filosofia analitica alimentato dalle scienze, il cui obiettivo è questa conoscenza aggregata ed epistemologicamente sostenibile su tutto ciò che siamo e conteniamo, che ci circonda e che in qualche modo si relaziona con noi. È qualcosa (...) di antico quanto il pensiero umano e, oltre a utilizzare elementi di cosmologia scientifica, racchiude tutto ciò che nella filosofia e nella scienza si riferisce all'universo e alla vita. Una cosmovisione non è un insieme d’idee, ipotesi e presupposti, ma un sistema basato su osservazione, analisi, prove e dimostrazione. Nessuna cosmovisione intende definire, stabilire, proporre, ma solo comprendere, analizzare e interpretare. Ognuno di noi costruisce e porta avanti la propria cosmovisione per tutta la vita, senza stabilire forme, come sfondo per il proprio pensiero e comportamento. Linguisticamente il termine “cosmovisione” deriverebbe dal tedesco, equivalente al concetto di“Weltanschauung”, utilizzato da diversi filosofi. Tuttavia, questa relazione linguistica non è applicabile perché contraddice ciò che proponiamo come cosmovisione. Questa parola tedesca rimanda a una visione prelogica o proto-sperimentale della realtà, con un contesto intuitivo e lontana da una conoscenza critica che non esisteva ancora al momento della sua formulazione. Senza dubbio, le cosmovisioni, nel senso in cui le intendiamo, ospitano e utilizzano questi elementi proto-sperimentali o prelogici che includono la storia, l’inconscio collettivo e tutti gli archetipi che portiamo con noi. Tuttavia, nel concetto che qui applichiamo, la cosmovisione va ben oltre questo contenuto, dapprima sottoponendolo costantemente al pensiero critico attuale e, infine, facendo dell'esperienza analitica (e non del pensiero o dell'intuizione stessa) il suo universo reale. In questo lavoro, cerchiamo di delineare una cosmovisione basata sulle realtà che la scienza offre oggi. Non proponiamo, in nessun momento, di fare scienza; o teorizzare la filosofia, ma cercheremo sempre di essere supportati da loro o, almeno, protetti da loro dalle distorsioni cognitive che abitualmente ci portiamo dietro.

It is well-known that the global structure of every space-time model for relativistic cosmology is observationally underdetermined. In order to alleviate the severity of this underdetermination, it has been proposed that we adopt the Cosmological Principle because the Principle restricts our attention to a distinguished class of space-time models (spatially homogeneous and isotropic models). I argue that, even assuming the Cosmological Principle, the topology of space remains observationally underdetermined. Nonetheless, I argue that we can muster reasons to prefer various topological (...) properties over others. In particular, I favor the adoption of multiply connected universe models on grounds of (i) simplicity, (ii) Machian considerations, and (iii) explanatory power. We are able to appeal to such grounds because multiply connected topologies open up the possibility of finite universe models (consistent with our best data), which in turn avoid thorny issues concerning the postulation of an actually infinite universe.

What constitutes a scientific discovery? What role do discoveries play in science, its dynamics and social practices? Must every discovery be attributed to an individual discoverer (or a small number of discoverers)? The paper explores these questions by first critically examining extant philosophical explications of scientific discovery—the models of scientific discovery, propounded by Kuhn, McArthur, Hudson, and Schindler. As a simple, natural and powerful alternative, we proffer the “change-driver model”: in a nutshell, it takes discoveries to be cognitive scientific results (...) that have epistemically advanced science. The model overcomes the shortcomings of its precursors, whilst preserving their insights. We demonstrate its intensional and extensional superiority, especially with respect to the link between scientific discoveries and the dynamics of science, as well as the award system of science. Both as an illustration, and as an application to a recent scientific and political controversy, we apply the considered models of discovery to one of the most momentous discoveries of science: the expansion of the universe. We oppose the 2018 proposal of the International Astronomers’ Union as too simplistic vis-`a-vis the historical complexity of the episode. The change- driver model yields a more nuanced and circumspect verdict: (i) The redshift-distance relation shouldn’t be named the “Hubble-Lemaître Law”, but “Slipher-Lundmark-Hubble-Humason Law”; (ii) Its interpretation in terms of an expanding universe, however, Lemaître ought to be given credit for; but (iii) The establishment of the expansion of the universe, as an evidentially sufficiently warranted result, is a communal achievement, emerging in the 1950s or 1960s.

EXPANDED EDITION (eBook): -/- Infinity Is Not What It Seems...Infinity is commonly assumed to be a logical concept, reliable for conducting mathematics, describing the Universe, and understanding the divine. Most of us are educated to take for granted that there exist infinite sets of numbers, that lines contain an infinite number of points, that space is infinite in expanse, that time has an infinite succession of events, that possibilities are infinite in quantity, and over half of the world’s population believes (...) in a divine Creator infinite in knowledge, power, and benevolence. -/- According to this treatise, such assumptions are mistaken. In reality, to be is to be finite. The implications of this assessment are profound: the Universe and even God must necessarily be finite. -/- The author makes a compelling case against infinity, refuting its most prominent advocates. Any defense of the infinite will find it challenging to answer the arguments laid out in this book. But regardless of the reader’s position, FOREVER FINITE offers plenty of thought-provoking material for anyone interested in the subject of infinity from the perspectives of philosophy, mathematics, science, and theology. -/- This electronic edition of FOREVER FINITE is offered free online for all and is expanded with content that does not appear in the published edition due to print production page limitations. From the Introduction to the Conclusion, Chapters 1–27 are identical to the published print edition, including the page numbering for the chapters. This electronic edition adds an appendix and associated content—specifically, updates to the book’s back matter (68 new endnotes, 17 new bibliographic references, 3 new figure credits, 14 new glossary terms) and front matter (an updated table of contents and this preface note).

We conduct a case study analysis of a proposal for the emergence of time based upon the approximate derivation of three grades of temporal structure within an explicit quantum cosmological model which obeys a Wheeler-DeWitt type equation without an extrinsic time parameter. Our main focus will be issues regarding the consistency of the approximations and derivations in question. Our conclusion is that the model provides a self-consistent account of the emergence of chronordinal, chronometric and chronodirected structure. Residual concerns relate to (...) explanatory rather than consistency considerations. (shrink)

This essay was published in the September 2023 edition of Griffith Observer. It is an examination of the curious friendship between writer Aldous Huxley and astronomer Edwin Hubble and its philosophical basis: empiricism. I hope that by consideration of these two thinker''s lives and work light may be shed on each of their ideas and on the 20th century conceptions of empiricism more broadly.

宇宙观是一个词汇，应该意味着一组基础，从中产生对 宇宙的系统性理解，包括生命、我们所处的世界、自然 界、人类现象及其相互关系。因此，这是一种由科学支 持的分析哲学领域，其目标是对我们周围及与我们相关 的所有事物的综合而认识，并在认识上具有认识论的支 持。它是与人类思维一样古老的存在，并且除了运用科 学宇宙学的元素外，还涵盖了所有涉及宇宙和生命的哲 学和科学。 一个宇宙观并不是一组想法、假设和假定，而是一个基 于观察、分析、证据和论证的系统。没有一个宇宙观会 试图定义、确立或提出，而只是理解、分析和解释。每 个人在一生中构建和承载着自己的宇宙观，作为我们思 维和行为的背景。 从语言学角度来看，术语“宇宙观”来源于德语，相当 于多位哲学家所使用的“Weltanschauung”概念。然 而，这种语言上的关系并不适用，因为它与我们所提出 的宇宙观相悖。这个德语词指的是一种先前逻辑或原始 实验性的现实观，具有直觉性的背景，并且在其形成时 6 还不存在批判性的认识。毫无疑问，在我们理解的意义 上，宇宙观包含并使用了这些原始实验性或先前逻辑的 元素，包括历史、集体无意识和我们所承载的所有原型。 然而，在我们应用的概念中，宇宙观远远超越了这些内 容，首先是因为它不断地将其置于当前的批判性思维之 下，并最终使经验成为其真实的宇宙，而非仅仅是思维 或直觉。 安东尼奥·洛佩斯展示了这一内容的广度：1 “宇宙观并不是思维的产物。它并非源于简单 的求知欲望。对现实的理解是宇宙观形成的重 要时刻，但仅仅是其中之一。它源自生活的行 为，源自对生命的经验，源自我们心灵的整体 结构。将生命提升到意识中，在对现实的认识、 对生命的价值以及意志的现实性中，是人类在 生活观念的发展中所做的缓慢而艰难的工作。 （W. Dilthey, 1992 [1911]: 120）”。 -/- 在这项工作中，我们试图勾勒出一种基于当今科学所提 供的现实的宇宙观。我们在任何时候都不会试图进行科 学研究，或对哲学进行理论化，而始终努力在它们的支 持下，或至少在它们的保护下，免受我们通常所带有的 认知扭曲的影响。 .

Космовидение - термин, под которым следует понимать совокупность оснований, из которых возникает системное понимание Вселенной, таких ее составляющих, как жизнь, мир, в котором мы живем, природа, феномен человека, и их взаимосвязей. таким образом, это область аналитической философии, питаемая науками, целью которой является совокупное и эпистемологически устойчивое знание обо всем, чем мы являемся и что в нас содержится, что нас окружает и что так или иначе с нами связано. это старое, как человеческая мысль, понятие, которое не только использует элементы научной космологии, (...) но и охватывает все, что относится к вселенной и жизни в философии и науке. Космовидение — это не набор идей, гипотез и предположений, а система, основанная на наблюдениях, анализе, доказательствах и демонстрациях. Космовидение не ставит своей целью определить, установить или предложить, а лишь понять, проанализировать и интерпретировать. Каждый из нас строит и переносит свое космовидение в течение жизни, не устанавливая форм, как фон для нашего мышления и поведения. С лингвистической точки зрения термин "космовидение" происходит от немецкого, эквивалентного понятию "Weltanschauung", используемому рядом философов. Однако эта лингвистическая связь неприменима, поскольку противоречит тому, что мы предлагаем в качестве космовидения. Это немецкое слово обозначает дологическое или протоэкспериментальное видение реальности, имеющее интуитивный контекст и далекое от критического знания, еще не существовавшего на момент его формулировки. Несомненно, космовидения в том смысле, как мы их понимаем, содержат и используют эти протоэкспериментальные или дологические элементы, включающие историю, коллективное бессознательное и все архетипы, которые мы носим в себе. Однако в той концепции, которую мы здесь применяем, космовидение выходит далеко за пределы этого содержания, во-первых, постоянно подчиняя его современному критическому мышлению и, наконец, делая аналитический опыт (а не саму мысль или интуицию) своей актуальной вселенной. Антониу Лопес раскрывает широту этого содержания: -/- "Космовидения не являются продуктом мысли. Они не возникают из простого желания знать. Постижение реальности - важный момент в ее конфигурации, но, тем не менее, только один. Оно исходит из жизненного поведения, из жизненного опыта, из структуры нашей психической совокупности. Возвышение жизни до сознания в познании реальности, в оценке жизни и в волевой реальности — это медленная и тяжелая работа, которую проделало человечество в развитии представлений о жизни". (В. Дильтей, 1992 [1911]: 120)". . В данной работе мы стремимся изложить космовидение, основанное на тех реалиях, которые сегодня предлагает наука. Мы ни в коем случае не собираемся заниматься наукой или теоретизировать философию, но всегда будем стремиться опираться на них или, по крайней мере, защищаться ими от тех когнитивных искажений, которые мы обычно несем.

Purpose: The purpose of the discussion is to call for an experimental trial in order to optimize the sociology of knowledge in the astronomical and cosmological sciences from a cognitive science and developmental psychology perspective. The potential of such experimental trial may also correlate developmental psychology with cosmology and astrophysics, therefore, contribute to public health from an astrobiological perspective. -/- Method: The discussion adopts a philosophizing method for the multidisciplinary and trans-disciplinary proposal, with the hypothesis that proton decay in cosmology (...) is correlative to neuronal development in human biochemistry. The method adopts a humanitarian paradigm of pragmatism in natural mutation from cosmic changes, in an exploratory heuristics for hydro-sampling of mutational potentials from environmental factors in cosmological large-scale structure. -/- Result: With an initial assessment on existing technologies, the potentials of the big data trend in astronomy and astrophysics can be applied to data analysis with solid-state electrolytes in sensor baselines to nuclear medicine methods.

The System of the World, Isaac Newton's first draft for the third volume of his classic work Philosophiae Naturalis Principia Mathematica (1687; Mathematical Principles of Natural Philosophy), is an important document in the history of science, using the principles of mechanics to construct the first complete scientific system on the workings of the universe in human history. -/- This book of 78 treatises briefly describes the principles established in the first two volumes of the Mathematical Principles of Natural Philosophy, then (...) applies these principles to the derivation of the actual orbits of the solar system and comets, laying out in layman's terms the universality of the law of gravitation and, from this, studying the shape of the earth, explaining the planetary precession and the tides of the oceans, probing the motion of the moon, and determining the orbits of comets. In this book, Newton does not construct abstract mathematical models, but analyses them in relation to astronomical phenomena, using only a small amount of mathematical language to explain these intriguing elements, making its content suitable for a general audience. -/- The appendices of this Chinese translation by Haixuan Pan(潘海璇) include Life of Sir Issac Newton by N. W. Chittenden, Newtonian Studies by Alexandre Koyré, which introduce Newton's life and main achievements, as well as the debates and evaluations of the main academic views of Newton by the leading philosophers and scientists of the time, and are important supplementary and reference materials when reading The System of the World.

An introduction [version eight] to a worldview called Rond, which is based on ideas from science, philosophy, and spirituality and designed to help one understand the nature of existence and cope with the human condition. With regard to philosophy: Rond is based on the concept of rondure as applied to aesthetics, ontology, metaphysics, cosmology, scientific phenomenology, philosophy of evolution, philosophy of mind, philosophy of conduct (including axiology, ethics, political philosophy, etc.), and epistemology.

This is a version of a book chapter included in a mss on Hegel and the Absolute. It deals with metaphysical issues in Big Bang cosmology (the Big Crunch, the Big Chill, the anthropic principle, singularities...) from a Hegelian point of view. If human consciousness is an undeniable feature of the universe, then can we not say that the universe possesses or has possessed consciousness and therefore is or has been conscious? Similarly, Hegel's Absolute knows itself through the self-knowing agency (...) of human thought. And so should we not attribute to the universe the same divine existence that Hegel's Encyclopedia evokes, in its last paragraph where he refers to Aristotle's self-contemplating, self-enjoying god?

In Logik der Forschung (1934) and later works, Karl Popper proposed a set of methodological rules for scientists. Among these were requirements that theories should evolve in the direction of increasing content, and that new theories should only be accepted if some of their novel predictions are experimentally confirmed. There are currently two, viable theories of cosmology: the standard cosmological model, and a theory due to Mordehai Milgrom called MOND. Both theories can point to successes and failures, but only MOND (...) has repeatedly made novel predictions that were subsequently found to be correct. Standard-model cosmologists, by contrast, have almost always responded to new observations in a post-hoc manner, adjusting or augmenting their theory as needed to obtain correspondence with the facts. I argue that these methodological differences render a comparison of the two theories in terms of their ‘truthlikeness’ or ‘verisimilitude’ essentially impossible since the two groups of scientists achieve correspondence with the facts in fundamentally different ways, and I suggest that a better guide to the theories’ progress toward the truth might be the methodologies themselves.

This volume offers a new edition of the original text and an Italian translation of Dante Alighieri’s Questio de aqua et terra, discussed in Verona in 1320. The introductory apparatus and the textual commentary reconstruct the historical context of the quaestio (in the light of the debates on the nature of the elements and Aristotelian cosmology), its discussions in the historiography of science and philosophy, and the fortune of the text in its editions from the sixteenth century onwards.

We argue that the epistemic functions of replication in science are best understood by their role in assessing kinds of experimental error. Direct replications serve to assess the reliability of an experiment through its precision: the presence and degree of random error. Conceptual replications serve to assess the validity of an experiment through its accuracy: the presence and degree of systematic errors. To illustrate the aptness of this view, we examine the Hubble constant controversy in astronomy, showing how astronomers have (...) responded to the concordances and discordances in their results by carrying out the different kinds of replication that we identify, with the aim of establishing a precise, accurate value for the Hubble constant. We contrast our view with Machery’s “re-sampling” account of replicability, which maintains that replications only assess reliability. (shrink)

Absolute nothing is the absence of our universe and its laws. Without these rules, nothingness has infinite potential. This implies that within the infinite probability of nothing, infinity can emerge. This would be expressed through infinite universes like our own. Infinite of these universes will differ by several particles, appearing and disappearing for no reason other than fulfilling every possibility. This universe is the product of a greater realisation of infinity and we can test this theory via the measurement of (...) our universe’s most fundamental particles appearing and disappearing for no discernible internal reason (random to our perspective).

It is not by thinking that we create worlds. It is by understanding the world that we learn to think. Cosmovision is a term that should mean a set of foundations from which emerges a systemic understanding of the Universe, its components as life, the world we live in, nature, human phenomena, and their relationships. It is, therefore, a field of analytical philosophy fed by the sciences, whose objective is this aggregated and epistemologically sustainable knowledge about everything that we are (...) and contain, that surrounds us, and that relates to us in any way. It is something as old as human thought, and, in addition to using elements of scientific cosmology, it encompasses everything in philosophy and science that refers to the universe and life. A cosmovision is not a set of ideas, hypotheses, and assumptions but a system based on observation, analysis, evidence, and demonstration. No cosmovision intends to define, establish, or propose but only to understand, analyse, and interpret. Each of us builds and transports his cosmovision throughout life, without establishing forms, as a background for our thinking and behaviour. Linguistically, the term “cosmovision” would derive from the German, equivalent to the concept of “ Weltanschauung,” as used by several philosophers. However, this linguistic relationship is not applicable because it contradicts what we propose as a cosmovision. This German word refers to a pre-logical or proto- experimental vision of reality, with an intuitive context and far from critical knowledge still non-existent at the time of its formulation. Undoubtedly, cosmovisions, in the sense in which we understand them, house and use these proto-experimental or pre-logical elements that include history, the collective unconscious, and all the archetypes we carry. However, in the concept that we apply here, the cosmovision goes far beyond this content, firstly by constantly submitting it to present critical thinking, and finally by making the analytic experience ( and not the thought itself or intuition) its actual universe. António Lopes expose the breadth of this content: -/- "Cosmovisions are not the product of thought. They do not spring from the simple desire to know. The apprehension of reality is an important moment in its configuration, but, nevertheless, it is only one. It comes from the vital conduct, from the experience of life's evaluation, and from the structure of our psychic totality. The elevation of life to consciousness in the knowledge of reality, in the valuation, and in the volitional reality is the slow and arduous work that humanity has done in the development of the conceptions of life. (W. Dilthey, 1992 [1911]: 120)”(1) -/- In this work, we seek to outline a cosmovision based on the realities that science offers today. We do not propose, at any time, to do science; or theorise philosophy, but we will always seek to be supported by them or, at least, protected by them from the cognitive distortions that we usually carry. ________________________________________________ (1) Lopes , Antonio – “ Weltanschauung (Cosmovision)” (2009 ) in Carlos Ceia's E-Dictionary of Literary Terms. -/- .

In the contemporary philosophy of mind and consciousness studies, views such as panpsychism or theories of universal consciousness, have enjoyed a recent renaissance of metaphysical speculations in Western philosophy. Its similarities with Eastern philosophical traditions went not unnoticed. However, the potential contribution that the evolutionary cosmology of the Indian poet, mystic and philosopher Sri Aurobindo can offer to these ontologies, remains largely unknown or unexplored. Here, consciousness, mind, life, matter and evolution are interpreted in an extended metaphysical framework, uniting Western (...) and Eastern traditions inside a modern philosophical system where materialism, panpsychism, cosmopsychism and philosophical idealism are not seen as irreconcilable exclusives, but different points of view that can be reconciled in a synthesis of knowledge, as envisioned from higher states of consciousness. This integral view of reality offers a conceptual platform that can complement and incorporate current theoretical approaches in modern philosophy, where their present internal inconsistencies do not emerge, and can be suggestive for scientists as well, especially in the fields of biology and physical sciences.

El presente artículo tiene por propósito construir una interpretación de La docta ignorancia de Nicolás de Cusa que articula su contexto histórico-cultural con la obra para ofrecer un sentido: la limitación de la razón humana para aprehender una verdad absoluta y las propuestas de una armonía interreligiosa y una reestimación del cosmos como consecuencias. Ello implica (I) reconstruir el horizonte sobre el cual surge y con el cual dialoga Nicolás de Cusa; (II) elaborar una interpretación crítica de La docta ignorancia (...) que muestre su estructura conceptual; y (III) descifrar la manera específica en que la obra de Cusa responde a su horizonte planteándose un sentido. Lo anterior sustenta una interpretación no lineal del texto de Cusa que le representa como crítico radical, no sólo reformador, de cuestiones filosóficas medievales, al limitar los alcances de la ontología y señalar un ámbito metafísico incognoscible.

Several approaches to developing a theory of quantum gravity suggest that spacetime—as described by general relativity—is not fundamental. Instead, spacetime is supposed to be explained by reference to the relations between more fundamental entities, analogous to `atoms' of spacetime, which themselves are not (fully) spatiotemporal. Such a case may be understood as emergence of \textit{content}: a `hierarchical' case of emergence, where spacetime emerges at a `higher', or less-fundamental, level than its `lower-level' non-spatiotempral basis. But quantum gravity cosmology also presents us (...) with the possibility of emergence of \textit{context}: where spacetime emerges from some `prior' non-spatiotemporal state (replacing the Big Bang), due to particular conditions in the early universe. I present a general conception of emergence which is plausibly able to accommodate both pictures. This is a positive conception that does not rely on a failure of reduction or explanation in any sense (indeed, reduction is a necessary feature of quantum gravity, and is useful in understanding emergence in this case). I also consider the possibility that the distinction between content- and context- based explanations is blurred, or usefully `collapsed', in the case of spacetime emergence. (shrink)

Scientific realism driven by inference to the best explanation (IBE) takes empirically confirmed objects to exist, independent, pace empiricism, of whether those objects are observable or not. This kind of realism, it has been claimed, does not need probabilistic reasoning to justify the claim that these objects exist. But I show that there are scientific contexts in which a non-probabilistic IBE-driven realism leads to a puzzle. Since IBE can be applied in scientific contexts in which empirical confirmation has not yet (...) been reached, realists will in these contexts be committed to the existence of empirically unconfirmed objects. As a consequence of such commitments, because they lack probabilistic features, the possible empirical confirmation of those objects is epistemically redundant with respect to realism. (shrink)

In his [1937, 1938], Paul Dirac proposed his “Large Number Hypothesis” (LNH), as a speculative law, based upon what we will call the “Large Number Coincidences” (LNC’s), which are essentially “coincidences” in the ratios of about six large dimensionless numbers in physics. Dirac’s LNH postulates that these numerical coincidences reflect a deeper set of law-like relations, pointing to a revolutionary theory of cosmology. This led to substantial work, including the development of Dirac’s later [1969/74] cosmology, and other alternative cosmologies, such (...) as the Brans-Dicke modification of GTR, and to extensive empirical tests. We may refer to the generic hypothesis of “Large Number Relations” (LNR’s), as the proposal that there are lawlike relations of some kind between the dimensionless numbers, not necessarily those proposed in Dirac’s early LNH. Such relations would have a profound effect on our concepts of physics, but they remain shrouded in mystery. Although Dirac’s specific proposals for LNR theories have been largely rejected, the subject retains interest, especially among cosmologists seeking to test possible variations in fundamental constants, and to explain dark energy or the cosmological constant. In the first two sections here we briefly summarize the basic concepts of LNR’s. We then introduce an alternative LNR theory, using a systematic formalism to express variable transformations between conventional measurement variables and the true variables of the theory. We demonstrate some consistency results and review the evidence for changes in the gravitational constant G. The theory adopted in the strongest tests of Ġ/G, by the Lunar Laser Ranging (LLR) experiments, assumes: Ġ/G = 3(dr/dt)/r – 2(dP/dt)/P – (dm/dt)/m, as a fundamental relationship. Experimental measurements show the RHS to be close to zero, so it is inferred that significant changes in G are ruled out. However when the relation is derived in our alternative theory it gives: Ġ/G = 3(dr/dt)/r – 2(dP/dt)/P – (dm/dt)/m – (dR/dt)/R. The extra final term (which is the Hubble constant) is not taken into account in conventional derivations. This means the LLR experiments are consistent with our LNR theory (and others), and they do not really test for a changing value of G at all. This failure to transform predictions of LNR theories correctly is a serious conceptual flaw in current experiment and theory. (shrink)

The present volume collects essays on the philosophical foundations of quantum theories of gravity, such as loop quantum gravity and string theory. Central for philosophical concerns is quantum gravity's suggestion that space and time, or spacetime, may not exist fundamentally, but instead be a derivative entity emerging from non-spatiotemporal degrees of freedom. In the spirit of naturalised metaphysics, contributions to this volume consider the philosophical implications of this suggestion. In turn, philosophical methods and insights are brought to bear on the (...) foundations of quantum gravity itself. For instance, the idea of functionalism, borrowed from the philosophy of mind and discussed by several essays, exemplifies this mutual interaction the collection seeks to foster. (shrink)

The second law of thermodynamics is traditionally interpreted as a coarse-grained result of classical mechanics. Recently its relation with quantum mechanical processes such as decoherence and measurement has been revealed in literature. In this paper we will formulate the second law and the associated time irreversibility following Everett’s idea: systems entangled with an object getting to know the branch in which they live. Accounting for this self-locating knowledge, we get two forms of entropy: objective entropy measuring the uncertainty of the (...) state of the object alone, and subjective entropy measuring the information carried by the self-locating knowledge. By showing that the summation of the two forms of entropy is a conserved and perspective-free quantity, we interpret the second law as a statement of irreversibility in knowledge acquisition. This essentially derives the thermodynamic arrow of time from the subjective arrow of time, and provides a unified explanation for varieties of the second law, as well as the past hypothesis.

This is a summary presentation of TAU, a theory proposed to explain relativity and unify physics. It is a radical change, because it proposes six dimensions of space, instead of the usual three (normal physics) or nine (string theory). It starts with an alternative foundation for Special Relativity, and leads to a unified theory of physics. It is a realist theory because it is realist about space and time. The TAU concept is briefly introduced here, and its results explained in (...) three main areas, particles, gravity and cosmology. In these areas it makes strong predictions and has several tests. This presentation is based around these applications and the key questions of completing a full particle model, and completing tests of gravity and tests of cosmology. These will decide its fate as an empirical theory. The aim here is to give an overview, in reasonable detail for generalists to see how the model works, but with a minimum of theoretical derivations, so we do not get too bogged down in equations. There are a lot of illustrations instead. Please note this is only a survey of the theory, and a more detailed introduction with proofs follows in Chapters 2-6, where it is developed in stages. In the first half here, we go quickly over the main concepts, in the second half, we give some equations for cosmology and gravity solutions in more detail, because they are more novel. (shrink)

To demarcate the limits of experimental knowledge, we probe the limits of what might be called an experiment. By appeal to examples of scientific practice from astrophysics and analogue gravity, we demonstrate that the reliability of knowledge regarding certain phenomena gained from an experiment is not circumscribed by the manipulability or accessibility of the target phenomena. Rather, the limits of experimental knowledge are set by the extent to which strategies for what we call ‘inductive triangulation’ are available: that is, the (...) validation of the mode of inductive reasoning involved in the source-target inference via appeal to one or more distinct and independent modes of inductive reasoning. When such strategies are able to partially mitigate reasonable doubt, we can take a theory regarding the phenomena to be well supported by experiment. When such strategies are able to fully mitigate reasonable doubt, we can take a theory regarding the phenomena to be established by experiment. There are good reasons to expect the next generation of analogue experiments to provide genuine knowledge of unmanipulable and inaccessible phenomena such that the relevant theories can be understood as well supported. This article is part of a discussion meeting issue ‘The next generation of analogue gravity experiments’. (shrink)

The classic example of a successful research program is Newton's gravitational theory, probably the most successful Lakatosian research program. Initially, Newton's gravitational theory faced a lot of "anomalies" ("counterexamples") and contradicted the observational theories that supported these anomalies. But supporters of the Newtonian gravity research program have turned every anomaly into corroborating cases. Moreover, they themselves pointed to counterexamples which they then explained through Newtonian theory . DOI: 10.13140/RG.2.2.32489.85601.

This is an elaboration and a critique of Ibn Arabi's cosmology written in his book "Shajarah Al-Kawn".

Most scientists would hold that science has not established that the cosmos is physically comprehensible – i.e. such that there is some as-yet undiscovered true physical theory of everything that is unified. This is an empirically untestable, or metaphysical thesis. It thus lies beyond the scope of science. Only when physics has formulated a testable unified theory of everything which has been amply corroborated empirically will science be in a position to declare that it has established that the cosmos is (...) physically comprehensible. But this argument presupposes a widely accepted but untenable conception of science which I shall call standard empiricism. According to standard empiricism, in science theories are accepted solely on the basis of evidence. Choice of theory may be influenced for a time by considerations of simplicity, unity, or explanatory capacity, but not in such a way that the universe itself is permanently assumed to be simple, unified or physically comprehensible. In science, no thesis about the universe can be accepted permanently as a part of scientific knowledge independently of evidence. Granted this view, it is clear that science cannot have established that the universe is physically comprehensible. Standard empiricism is, however, as I have indicated, untenable. Any fundamental physical theory, in order to be accepted as a part of theoretical scientific knowledge, must satisfy two criteria. It must be (1) sufficiently empirically successful, and (2) sufficiently unified. Given any accepted theory of physics, endlessly many empirically more successful disunified rivals can always be concocted – disunified because they assert that different dynamical laws govern the diverse phenomena to which the theory applies. These disunified rivals are not considered for a moment in physics, despite their greater empirical success. This persistent rejection of empirically more successful but disunified rival theories means, I argue, that a big, highly problematic, implicit assumption is made by science about the cosmos, to the effect, at least, that the cosmos is such that all seriously disunified theories are false. Once this point is recognized, it becomes clear, I argue, that we need a new conception of science which makes explicit, and so criticizable and improvable the big, influential, and problematic assumption that is at present implicit in physics in the persistent preference for unified theories. This conception of science, which I call aim-oriented empiricism, represents the assumption of physics in the form of a hierarchy of assumptions. As one goes up the hierarchy, the assumptions become less and less substantial, and more and more nearly such that their truth is required for science, or the pursuit of knowledge, to be possible at all. At each level, that assumption is accepted which (a) best accords with the next one up, and (b) has, associated with it the most empirically progressive research programme in physics, or holds out the greatest hope of leading to such an empirically progressive research programme. In this way a framework of relatively insubstantial, unproblematic, fixed assumptions and associated methods is created, high up in the hierarchy, within which much more substantial and problematic assumptions and associated methods, low down in the hierarchy, can be changed, and indeed improved, as scientific knowledge improves. One assumption in this hierarchy of assumptions, I argue, is that the cosmos is physically comprehensible – that is, such that some yet-to-be-discovered unified theory of everything is true. Hence the conclusion: improve our ideas about the nature of science and it becomes apparent that science has already established that the cosmos is physically comprehensible – in so far as science can ever establish anything theoretical.

Typically, a less fundamental theory, or structure, emerging from a more fundamental one is an example of synchronic emergence. A model emerging from a prior model upon which it nevertheless depends is an example of diachronic emergence. The case of spacetime emergent from quantum gravity and quantum cosmology challenges these two conceptions of emergence. Here, I propose two more-general conceptions of emergence, analogous to the synchronic and diachronic ones, but which are potentially applicable to the case of emergent spacetime: an (...) inter-level, hierarchical conception, and an intra-level, ‘flat’ conception. I then explore whether, and how, these ideas may be applicable in the case of several putative examples of relativistic spacetime emergent from the non-spatiotemporal structures described by different approaches to quantum gravity, and of spacetime emergent from a non-spatiotemporal ‘big bang’ state according to different examples of quantum cosmology.

The problem of surviving the end of the observable universe may seem very remote, but there are several reasons it may be important now: a) we may need to define soon the final goals of runaway space colonization and of superintelligent AI, b) the possibility of the solution will prove the plausibility of indefinite life extension, and с) the understanding of risks of the universe’s end will help us to escape dangers like artificial false vacuum decay. A possible solution depends (...) on the type of the universe’s ending that may be expected: very slow heat death or some abrupt end, like a Big Rip or Big Crunch. We have reviewed the literature and identified several possible ways of survival the end of the universe, and also suggest several new ones. There are seven main approaches to escape the end of the universe: use the energy of the catastrophic process for computations, move to a parallel world, prevent the end, survive the end, manipulate time, avoid the problem entirely or find some meta-level solution.
