Something That May Explain The Ageing Of Universe Issue.
 

The idea is simple, what happens when two supermassive objects (just like the ones which deform space and time, this is, black holes) collide? I don't know much about their physics but my idea is that both objects produce an explosion, as big as Big Bang.

Just think about the mass of a star, or more; concentrated in the smallest space, and the energy that object has. Wouldn't that reach a supercritical level at some point where this object should release all the energy? And what if this level was reached by colliding two similar objects in the deformed space?

How if there was more than a Big Bang occurring in our Universe?

Actually when two supermassive black holes collide, surprisingly, there isn't a traditional 'Hollywood' explosion where there's huge masses released in all directions. When two of such objects collide they either merge to form a larger black hole or one of them is kicked out of the system. The one that is thrown out of the system of bodies(usually this 'system' is a galaxy and there are supermassive black holes in virtually every regular galaxy in the universe), it enters the accretion disk of gas and dust that orbit the system of black holes and as this black hole gobbles up this gas and dust, the accretion disk blazes for thousands of years. The only energy released (but nonetheless gargantuan) that is detectable are gravitational waves or 'ripples' when such an event occurs.

Simulations show this:

The blue plane is spacetime







Any possible 'explosion' can't occur because not even light can escape the gravity well of one supermassive black let alone two, even if it was possible to have an explosion we wouldn't be able to detect it in the visible wavelenghts of light as it wouldn't be able to reach us. What is detectable are the X-Rays given off when the second black hole is thrown into the accretion disk and becomes active.

Your guess is moderately close to the Big Crunch Theory, that the gravity of all the bodies of the universe gradually tugs it back into a singularity (or black hole but not necessarily the same) and the recoil would be another Big Bang.

wow, great video, thanks :)

Holy **** Could you imagine what would happen if this was anywhere near earth?

Everything on the Earth including us would be stretched and compressed many times per second as the gravitational troughs and crests pass through the Earth, virtually instant death for us and the destruction of the Earth as the planet is ripped apart and crushed. A very happy ending. :P
