Well, finally found something that goes along with my theoretical thoughts of the Universe:
The Universe is infinite, and spawns new Universes through the black hole process (in other words, matter is pulled in, crushed to a 'singularity', and then one day explodes to form yet another Universe (which explains what they call the Big Bang (which is thought to be the beginning of our particular Universe).
This process has always existed, and always will. There is no beginning or end to anything (except our lives here on Earth, which is another subject-and why we find it hard to believe it has all always existed, and always will).
So death is not the end, in a sense. It is a new beginning!
Guess I should have been an Astronomer or something :-)
