Enytopy on a Universe scale is real, it is enivitable and we have quantitative proof.

The form it takes can be observed today and is altering time relative to gravity and mass and energy at this time.

The ultimate black hole will give way to another existence on the "other side" like a mega example of virtual particles, but it will be the product of entropy and be a reduced fractal product of what the universe once was. The children universes of our universe will somtimes live on beyond the existence of its parents but they too will undergo entropy. This is an entropy of the entire system and not merely the breaking down of atomic and subatomic particles.

PS the latest Taggert book was a lesser example of the Field.
