Is there a godI assume you are referring to the possible "heat death" scenario postulated for the "end" of the universe.
This is generally considered to be a linear model with a definite beginning and a long tail-off to a point where the universe is so diffuse as to not be there at all.
Emotionally many people prefer cyclic models (with a new big bang following a big crunch, following...)
however, while there is still enough uncertainty remaining (in the cosmological observations), to allow for a cyclic model,
the balance of evidence is starting to tip away from it.
The question of "can a new universe be born from the death of the old", depends on the question of "how are new universes born".
There is very little that can be answered about that question.
There are physicists who are looking at ways of recognizing possible scenarios verses impossible scenarios
and plausible verses implausible scenarios
But these still leave the question far too nebulous to really make any properly meaningful statements about it.
