Big Crunch Theory
Big Crunch TheoryThe Big Crunch Theory is made possible by Big Bang cosmology, which states that all matter in the universe is now racing away from all other matter. If there is enough matter in the universe to create a gravitational force sufficient to bring this movement to a halt and to reverse its direction, then at some point in the remote future all matter in the universe will converge into an infinitely dense point in space, resembling a massive black hole. The end of the universe would then resemble its beginning—a singularity at which the laws of physics as we know them no longer apply. Such a universe is called a closed universe.

heat death of the Universe
heat death of the Universe The long-term fate of the Universe, according to the laws of thermodynamics, in which all matter will eventually reach the same temperature. In this condition no energy is available for doing work and the entropy of the Universe is at a maximum. This outcome was predicted by the German physicist Rudolf Julius Emmanuel Clausius (1822–88), who introduced the concept of entropy.
