The cosmological constant and cosmological change
Physics Today, 1977Is the Universe of infinite extent, or is it a finite system? Will it expand forever, or will it reach some maximum size before turning and collapsing upon itself like an inverse Big Bang? Just a few years ago, models of the conventional Friedman types were showing consistent, albeit tentative, evidence for an open, ever-expanding Universe. Since then,

EFFECTIVE COSMOLOGICAL CONSTANT IN BRANE COSMOLOGY
International Journal of Modern Physics D, 2006We consider a brane-world of co-dimension one without reflection symmetry. Through it, we give a possible explanation of the great discrepancy between the vacuum energy and the observed cosmological constant without contradiction to the knowledge we have about our Universe. We also show the gravity observed will be standard four-dimensional gravity as

About neutrinos, we only know that the three left handed \(\nu_{\rm e_{\rm{L}}}\ ,\ \nu_{\mu_{\rm{L}}}\ ,\ \nu_\tau\) exist, that they have weak interactions and that they are much lighter than their corresponding charged leptons. They may be massive or massless, stable or not.

Hindu cosmology has to do also with cosmogony and with cosmography. Within the context of Hindu cosmology, it is not easy to mark a definite border between physical, religious or mythological, and philosophical cosmology. The best way to distinguish different topics within this conceptual area is to refer to their different sources, mainly the four ...
