The Universe

They now say that the universe is expanding and accelerating. It's not only getting bigger but bigger faster! Now, every human knows, as matter aproaches the speed do light, it gets heavier and closer to infinite mass.
The most heaviest thing in the universe is the black hole. The curious thing about the black hole is that it has an event horizon, the point of no return. Every thing, even light, that enters the event horizon, never comes out, and on top of this, time goes all wonky because of the intense gravitation. If an observer was to fall into an event horizon, time would seem normal to them but when they look back to where they were, all the stars would be supernova-ing
and they would witness the universe come to an end!
When a gun is shot, the bullit starts to slow after the initial big bang. When you drop a ball from a tree, it accelerates to the ground. Is the whole universe falling toward a future singularity?
