What the Universe will look like when its essentially dead (This is called heat death)

Itll die one day aaaaaaaaand itll get devoured by
One huge mega blackhole causing
Big crunch a time-revsersed biG bang
Before the big bang there was a dead universe. Before our own.
A Mega Black hole completely Devoured it or the previous universe shrunk to a tiny singularity expanding forming our universe but.
The universe will have the same fate as the previous universe.
