Is the universe entropic?

Question

Muaha :]

Answer 1

Many theories claim that it is. If it's not, than the universe is infinite. I don't have the credentials to argue between the finite and infinite universe models.

Answer 2

In cosmology, the entropic description of our universe is a hypothetical tendency for the universe to attain a state of maximum homogeneity in which all matter is at a uniform temperature (heat death).  All recent research indicates that our universe will continue to expand indefinitely until the so-called "heat death" is reached when there will be absolutely no energy or mass left.

Answer 3

Even if the universe is finite, the expansion of space is an input of new space which soaks up entropy. So the universe is not a closed system, and the 2nd law of thermodynamics does not apply.

If the universe is infinite, then without expansion the question of open or closed would be indeterminate. But again, expansion makes it an open system.

In my Fractal Foam Model of Universes, our universe exports its entropy to the next larger-scale universe and the next smaller-scale universe exports its entropy to us. However, the direction of time alternates from one universe to the next, turning an export of entropy from one universe into an import of disentropy into the next universe.
