It is thought that the Universe has no edge….I like to think that it does in the form of Black holes/singularities…..and I am pondering whether or not gravity is a function of Time and not of Matter.
Matter in spacetime has mass, but not all mass has gravity….unless it has motion through spacetime which changes its passage through time relative to all other matter…
The M or String theorists have speculated that in every atom there exists a particle called a Graviton upon which the force of gravity is transmitted and they hope to find proof of its existance when the newest and most powerful particle accelerator is finished.
I wonder if they may be barking up the wrong tree…..ah well …we’ll see soon enough.

On a different note,
I do not believe in God. I know that God exists, belief is’nt necessary for God to exist, only for religion. I do not believe in religion.
Asking me if I believe in God is like asking me if I believe in the mailman, which to me is rather silly.
