  1. On the uncertainty principle in Rindler and Friedmann spacetimes.Thomas Schürmann - 2020 - European Physical Journal C 80.
    We revise the extended uncertainty relations for the Rindler and Friedmann spacetimes recently discussed by Dabrowski and Wagner in [9]. We reveal these results to be coordinate dependent expressions of the invariant uncertainty relations recently derived for general 3-dimensional spaces of constant curvature in [10]. Moreover, we show that the non-zero minimum standard deviations of the momentum in [9] are just artifacts caused by an unfavorable choice of coordinate systems which can be removed by standard arguments of geodesic completion.

  2. A Philosophical Rejection of The Big Bang Theory.Khuram Rafique - 2018 - Realism & Physics.
    Scientific inquiry takes onward course from the point where previous scientists had reached. But philosophical analysis initiates from scratch. Philosophy questions everything and chooses starting point for itself after having ruled out all the unsubstantiated and doubtful elements of the topic under study. Secondly, known realities must make sense. If a theory is officially 'counterintuitive', then either it is mere fiction or at the most; a distorted form of truth. This book's analysis is based on the philosophical principle that knowledge (...)

    Cosmological Black Holes and the Direction of Time.Gustavo E. Romero, Federico G. López Armengol & Daniela Pérez - 2018 - Foundations of Science 23 (2):415-426.
    Macroscopic irreversible processes emerge from fundamental physical laws of reversible character. The source of the local irreversibility seems to be not in the laws themselves but in the initial and boundary conditions of the equations that represent the laws. In this work we propose that the screening of currents by black hole event horizons determines, locally, a preferred direction for the flux of electromagnetic energy. We study the growth of black hole event horizons due to the cosmological expansion and accretion (...)

  4. Arendt's anti-humanism of labour.Nicholas H. Smith - 2019 - European Journal of Social Theory 2 (22):175-190.
    The aim of this article is to situate Arendt’s account of labour as a critical response to humanisms of labour, or put otherwise, to situate it as an anti-humanism of labour. It compares Arendt’s account of labour with that of the most prominent humanist theorist of labour at the time of the composition of The Human Condition: Georges Friedmann. Arendt’s and Friedmann’s accounts of labour are compared specifically with respect to the range of capacities, social relations, and possibilities (...)

  5. Tests cosmologiques gravitationnels: l'univers en expansion.Sfetcu Nicolae - manuscript
    Les modèles cosmologiques actuels sont construits sur la base de la relativité générale. Les solutions des équations spécifiques, Friedmann-Lemaître-Robertson-Walker, permettent de modéliser l'évolution de l'univers à partir du Big Bang . Certains paramètres de l'univers ont été établis par des observations. Sur la base de ces données et d'autres données d'observation, les modèles peuvent être testés . Les observations sur la vitesse d'expansion de l'univers permettent d'estimer la quantité totale de matière, dont certaines théories prédisent que 90% sont de (...)

  6. Teste gravitaționale cosmologice.Nicolae Sfetcu - manuscript
    Modelele cosmologice actuale sunt construite pe baza relativității generale. Soluțiile ecuațiilor specifice, Friedmann-Lemaître-Robertson-Walker permit modelarea evoluției universului pornind de la Big Bang. O parte din parametrii universului au fost stabiliți prin observații. Pe baza acestora, și altor date observaționale, se pot testa modelele. Predicțiile includ abundența inițială de elemente chimice formate într-o perioadă de nucleosinteză în perioada Big Bang, structura ulterioară a universului, radiația cosmică de fond, etc. DOI: 10.13140/RG.2.2.22204.59525.

  7. Cosmological Tests of Gravity.Nicolae Sfetcu - manuscript
    The current cosmological models are built based on general relativity. The solutions of the specific equations, Friedmann-Lemaître-Robertson-Walker, allow to model the evolution of the universe starting from the Big Bang. Some of the parameters of the universe have been established by observations. Based on these, and other observational data, the models can be tested. Predictions include the initial abundance of chemical elements formed in a period of nucleosynthesis during the Big Bang period, the subsequent structure of the universe, cosmic (...)

  8. O Conceito do Trabalho: da antiguidade ao século XVI.Emanuel Isaque Cordeiro da Silva - manuscript
    SOCIOLOGIA DO TRABALHO: O CONCEITO DO TRABALHO DA ANTIGUIDADE AO SÉCULO XVI -/- SOCIOLOGY OF WORK: THE CONCEPT OF WORK OF ANTIQUITY FROM TO THE XVI CENTURY -/- RESUMO -/- Ao longo da história da humanidade, o trabalho figurou-se em distintas posições na sociedade. Na Grécia antiga era um assunto pouco, ou quase nada, discutido entre os cidadãos. Pensadores renomados de tal época, como Platão e Aristóteles, deixaram a discussão do trabalho para um último plano. Após várias transformações sociais entre (...)
