There will be a bang! The reverse collapse of the universe to the point of singularity! Matter does not know the resting point, so heat death will not happen! The cycle is endless, compression is expansion!
What will END the Universe?!?!

There will be no endless expansion either, as the energy of expansion is being depleted and a new push is needed!

This TOTALLY makes sense.
One possible theory that will end the Universe (of black's army) can be a RUNAWAY QUEEN!!!
Or not...

As a result of the "Big Bang", matter"fills the voids in the space of the "Universe", and "black holes" are nothing but places that "matter" has not yet managed to penetrate!
There are lots of possible theories for how the universe will end, from black holes getting (too) strong to heat death. What do YOU think will end the Universe?
