So are you saying that you believe that the universe will end in this manner before a Big Crunch or big freeze scenario would occur?

Edited by The Cellar Door: 4/7/2016 2:58:05 AMYes. There are 3 possible shapes of the universe, and these shapes correspond to the theories regarding the end. Big Crunch corresponds to a spherical universe, a cyclic one. Big freeze corresponds to a hyperbolic one, which is the least likely due to the derivation of how "flat" the universe is. Heat death happens due to a flat universe, which the numbers favor by far over the spherical option.

When you say "flat universe", are you referring to a universe that is literally flat, or one that simply expands in such a manner rather than expanding in a spherical fashion?
-
Well obviously we perceive a 4 dimensional system, but the universe is flat in the sense that the energy density is constant everywhere we look.
-
Ah so 4 dimensional as in the XYZ axis +time being the 4th?
-
Yes, exactly.

Not sure I follow you. I've studied some astronomy but not that far.
