Observation in Cosmology

In his article “If Loud Aliens Explain Human Earliness, Quiet Aliens are also Rare”, Robin Hanson proposes the Grabby Alien Hypothesis, which proposes that extraterrestrial civilizations (ETIs) exist outside of our observable universe and are gradually expanding to fill the universe. The existence of such grabby aliens in our future expanding to fill all available niches puts a cosmic deadline on independently originating sources of life. This cosmic cutoff offers an explanation for why human observers seem to be relatively early (...) in spacetime, why the red dwarf stars seem to be inadequate for independently originating life, and why the Fermi Paradox remains unsolved. However, we should worry about Hanson’s proposal, since the Grabby Alien Hypothesis has its own paradoxical implication, namely that most observers in most reference classes should be grabby aliens themselves (Bostrom, 2002). Thus, oddly, finding ourselves not to be grabby alien observers, it seems Hanson is beholden to explain why we are not. Some possibilities for grabby alien observer alternatives can be offered, though none are particularly explanatorily appealing. In what follows, we will 1) attempt to restate in simple terms Hanson’s assumptions, and then 2) reassemble Hanson’s arguments, showing they lead to a paradox, and 3) consider which assumptions should be rejected and at what cost.

Introduction to alternative ontology of mind and physics based on the multi-dimensional model of A Geometric Theory of the Universe (Holster).

The Simulation Hypothesis proposes that all of reality is in fact an artificial simulation, analogous to a computer simulation. Outlined here is a method for programming relativistic mass, space and time at the Planck level as applicable for use in Planck Universe-as-a-Simulation Hypothesis. For the virtual universe the model uses a 4-axis hyper-sphere that expands in incremental steps (the simulation clock-rate). Virtual particles that oscillate between an electric wave-state and a mass point-state are mapped within this hyper-sphere, the oscillation driven (...) by this expansion. Particles are assigned an N-S axis which determines the direction in which they are pulled along by the expansion, thus an independent particle motion may be dispensed with. Only in the mass point-state do particles have fixed hyper-sphere co-ordinates. The rate of expansion translates to the speed of light and so in terms of the hyper-sphere co-ordinates all particles (and objects) travel at the speed of light, time (as the clock-rate) and velocity (as the rate of expansion) are therefore constant, however photons, as the means of information exchange, are restricted to lateral movement across the hyper-sphere thus giving the appearance of a 3-D space. Lorentz formulas are used to translate between this 3-D space and the hyper-sphere co-ordinates, relativity resembling the mathematics of perspective. (shrink)

We give a Bayesian argument showing that, even if your total empirical evidence confirms that you have zillions of duplicate Boltzmann Brains, that evidence does not confirm that you are a Boltzmann Brain. We also try to explain what goes wrong with several of the sources of the temptation for thinking that such evidence does have skeptical implications.

Our universe seems to be miraculously fine-tuned for life. Multiverse theories have been proposed as an explanation for this on the basis of probabilistic arguments, but various authors have objected that we should consider our total evidence that this universe in particular has life in our inference, which would block the argument. The debate thus crucially hinges on how Bayesian background and evidence are distinguished and on how indexical or demonstrative terms are analysed. The aim of this article is to (...) take a step back and examine these various aspects of Bayesian reasoning and how they affect the arguments. The upshot is that there are reasons to resist the fine-tuning argument for the multiverse, but the “this-universe-objection” is not one of them. (shrink)

The article summarizes the software tool on astrophysical analysis with multi-wavelength space telescope data. It recaps the evidence analysis conducted on the Kerr-Newman black hole (KNBH). It was written prior to the article Research on the Kerr-Newman Black Hole in M82 Confirms Black Hole and White Hole Juxtapose not soon after the experiment. The conducted analysis suggested Hawking radiation is caused by the movement of ergosurfaces of the BH and serves as the primal evidence for black hole and white hole (...) juxtapose. A later data exploration was conducted with the radiation trails in the multi-wavelength data. The evidences produced corroborates with Yale professor Priyamvada Natarajan's black hole seeds theory. It implies that the electromagnetic dynamic of fusion and fission temperature determines the pressure of surface tension on the macro particles, and the mass density of the BH is determined by the electromagnetic tension between the outer ergosurface and inner ergosurface. The ring singularity of the BH and the Penrose-Hawking singularity of the BH determine the spin and gravitational singularity of the BH. Inside the ergosurfaces, the BH singularities' backward inflow causes the vicinity's rate on feeding the BH. It makes the active galactic nuclei (AGN) a semi-closed system. The density pressure is released on threshold. During the mass exchange observed by energy momentum upon the AGN's open, the macroparticle composition of the BH changes with the galactic event. This causes the expansion rate of the galaxy and contraction rate of the BH. AGN types and their relative motions determine the expansion rate of the cosmic universe in a generalized quantitative thinking. The article concludes that BH spin is caused by the asymmetric motions of AGN in the BH system. A set of the nuclear resonance caused by BH and white hole (WH) oscillation is processed with the same set of data. (shrink)

The Simulation Hypothesis proposes that all of reality, including the earth and the universe, is in fact an artificial simulation, analogous to a computer simulation, and as such our reality is an illusion. In this essay I describe a method for programming mass, length, time and charge (MLTA) as geometrical objects derived from the formula for a virtual electron; $f_e = 4\pi^2r^3$ ($r = 2^6 3 \pi^2 \alpha \Omega^5$) where the fine structure constant $\alpha$ = 137.03599... and $\Omega$ = 2.00713494... (...) are mathematical constants and the MLTA geometries are; M = (1), T = ($2\pi$), L = ($2\pi^2\Omega^2$), A = ($4\pi \Omega)^3/\alpha$. As objects they are independent of any set of units and also of any numbering system, terrestrial or alien. As the geometries are interrelated according to $f_e$, we can replace designations such as ($kg, m, s, A$) with a rule set; mass = $u^{15}$, length = $u^{-13}$, time = $u^{-30}$, ampere = $u^{3}$. The formula $f_e$ is unit-less ($u^0$) and combines these geometries in the following ratio M$^9$T$^{11}$/L$^{15}$ and (AL)$^3$/T, as such these ratio are unit-less. To translate MLTA to their respective SI Planck units requires an additional 2 unit-dependent scalars. We may thereby derive the CODATA 2014 physical constants via the 2 (fixed) mathematical constants ($\alpha, \Omega$), 2 dimensioned scalars and the rule set $u$. As all constants can be defined geometrically, the least precise constants ($G, h, e, m_e, k_B$...) can also be solved via the most precise ($c, \mu_0, R_\infty, \alpha$), numerical precision then limited by the precision of the fine structure constant $\alpha$.

Some modern cosmological models predict the appearance of Boltzmann Brains: observers who randomly fluctuate out of a thermal bath rather than naturally evolving from a low-entropy Big Bang. A theory in which most observers are of the Boltzmann Brain type is generally thought to be unacceptable, although opinions differ. I argue that such theories are indeed unacceptable: the real problem is with fluctuations into observers who are locally identical to ordinary observers, and their existence cannot be swept under the rug (...) by a choice of probability distributions over observers. The issue is not that the existence of such observers is ruled out by data, but that the theories that predict them are cognitively unstable: they cannot simultaneously be true and justifiably believed.

Along the strike of this article we’ll try to perform two tasks. The first one is to review the world existence but not in form of concept but in form of modern scientific-philosophic system of views on the Universe structure and on the processes of formation and development of non-organic world, worlds of life and intelligence. The second one is to answer the question “what is the essence of human life?” through the scientific-philosophic understanding of the world existence.

I present my own vision of the material world's formation. I think this new cosmological model deepens and extends the modern points of view on the universe. It allows to follow the evolution of matter up to forming of human society. I had to rethink a lot and even to change and to surrender in some degree my points of view stated in my previous publications. But these changes had a partial character and naturally resulted from the evolution of my (...) views on the world's processes. The fundament stands still and and that is what I intend to present you. I owe my thanks to all those people who contributed to ny spiritual development, whose surnames will be mentioned in the text or in bibliographical list. Most of them are gone. But the charm of human life is that the biological death of a man does not necessarily abolish his social-intellectual immortality . (shrink)

This small book continues the theoretical study on the structure of the universe. It examines the category of “time” in the light of a new cosmological model proposed by the author in his book “The Origin of Mankind”. It is generally accepted that after researches of A. Einstein, А. Minkovsky and others space and time are considered in their interrelation, as the continuum. Nevertheless, the category of “time” is still a bone of contention and a cause of a great deal (...) of misunderstanding in contemporary science. In philosophy, mathematics, physics it has different meanings. In this book the author dares to give more precise definition of the category of “time” from the point of view of the contemporary level of knowledge. (shrink)
