It can be shown that this requires the violation of a basic principle of physics: energy conservation, although the level at which this violation is required is small enough not to have been tested by any experiment. The tired light theory is an other example of a theory in which a new ...
If we adopt the weak form of the cosmological principle, (M,g,γs) can be identified with the phenomenological background spacetime or phenomenological background solution (PBS), according to the notation introduced in [21]. In the same vein, we define phenomenological observers the collection ...
Convolutional Neural Networks (CNNs) are a cornerstone of the Deep Learning toolbox and have led to many breakthroughs in Artificial Intelligence. These networks have mostly been developed for regular Euclidean domains such as those supporting images, audio, or video. Because of their success, CNN...
Since a change in HOD parameters can result in a change in the number density of the galaxy sample and thus affect the shot-noise, the shot-noise can in principle be used to constrain the HOD parameters. We, therefore, perform an additional Fisher projection with the shot-noise kept in th...
(see Section 2.4) Einstein had hoped that normal matter is needed to curve the geometry; a demand, which—to him—was closely related to the Mach's principle. This hope, however, was soon shattered when de Sitter produced a solution to Einstein's equations with cosmological constant ...

But for ChaNGa, we find that determining the load based on a heuristic called the principle of persistence is more accurate. Based on this heuristic we use recent history to determine the load of near-future iterations. This scheme works well for single-stepping simulations at a relatively ...
The ease of measurement and their ability to test the cosmological principle make them an important component of modern cosmology research. The deceleration parameter is a crucial cosmological param- eter that characterizes the expansion rate of the universe. It is defined as the ratio of the ...
Foundations of Physics and Cosmology General Relativity 1Introduction The standard model of cosmology requires adiabatic primordial fluctuations as initial conditions set in the very early universe [1,2,3]. Fluctuations are adiabatic when all fields filling the universe agreed to share a slicing of the...
