I believe gravity will eventually smash all the galaxies with their own energy and mass. Not in the past, but in the future. Time rolls on.

Wait a minute here... What if two black holes collide? Would their consumed matter be expelled; or would they create a massive black hole?

Maybe so, maybe not. It could be that the universe is open and that all matter will ultimately be subjected to a 'big rip' as dark energy acceleration attains fantastically high values.

The coalescence of two black holes creates a more massive black hole, it's thought. Such an event should also be so violent as to produce gravitational ripples in spacetime, detectable in principle by us.

Traced backward in time, the ENTIRE universe must have been a MBH to begin with, so just HOW did it manage to INFLATE to it's present size?
