Thermodynamics and the Arrow of Time

To say an ‘Arrow of Time’ is to say that time itself is linear and one-directional. In thermodynamics, the second law dictates that everything moves in one-direction from a state of order towards disorder and entropy is the statistical measurement of this asymmetry in an isolated system. The universe is, for instance, this isolated system and as a consequence it is impossible to reverse this arrow of time and travel backwards just as much as the continuity of disorder will never decrease. Newton’ equations and other laws in physics, however, can be reversed and thus this ‘order’ is arrived from a state of equilibrium as it moves forward toward disorder. Read More

Gravitational Repulsion: Is Zero Building An Eternally Expanding Universe?

Non-inflationary theories of the genesis of the universe or what we know as the big bang effectively only discuss the hydrogen and helium particles etc &c., that fill the universe or what occurred after the birth of the universe, and now that evidence has been shown[1] that the universe is actually expanding, it has led to questions of what could have been prior to the bang in a much more sophisticated manner. And there are multiple theories, such as Brane collision or the collision of two dimensions or that the universe is formed from within a black hole, all of which are interesting particularly with new areas of thought viz., superstrings and the cyclic universe model, but certainly not as persuasive as cosmic inflation and the multiverse theory.
