Ok, here's a crazy theory!
What if the Big Bang wasn't the beginning but was the beginning of the end?
Before the Big Bang Matter may have been one, just one huge lump of everything, but it decayed or could no longer hold itself anymore. So it either blew apart and created the known universe that way or gradually decayed and created it slowly. But all the stars and planets are also decaying, gradually, atoms and mollecules and such like are falling away from their source so this is a lengthy decay, like a body burried in the soil. Gradually everything may just keep decaying untill theres just a mass of atoms floating about in nothingness, then maybe the atoms will break down, and it will continue to fall apart into infinately small, from something infinately large.
Dunno just a crazy idea, I'm full of them, speculations can be more fun than reality!

in that aspect it is a lot like the human body, or to be presice the cells in it, each one decays and is replaced by a new one, this in the end is what causes our death, as eventually the cells can't copy themselves as good anymore.

that is another reason why I think that the universe may be a giant body.

Yes I quite agree, we are maybe all part of a vast living organism!

Wasn't it "Animal House" where the teacher was dropping acid with the students and he described a whole universe as just a speck in his fingernail, and we in turn are just a speck in some larger beings finger nail, and so on, and so on...?

Yes I believe so, funny thought isn't it? Its a bit like MIB II where the universe is in a locker and there are more universes in different lockers smaller universes within universes! Ha ha, you could never prove something like that though could you?

Or what if we are all living something that has already happenend many times before? What if happens if the expanding universe runs out of energy before it "blows". It will collapse in on itself causing another big bang well what if this has been the routine for a very long time and what we experience as "Deja Vu" is something we actually really have lived, and psychics are people that have somehow found a way to remeber what has already happenend.....

What you're talking about is entropy. As of this moment, every system is decaying. Everything is made out of the same dot. And in the end, time and space is non-existent, because black holes are infinite density, and time is a manmade creation.

That's actually a great theory. As we have observed so far everything is slowly decaying and dying. So there could be quite a bit of truth to that. I believe that there is more than one universe, so maybe it could be an on going thing; Creation and destruction. The Universe is so grand in it's design, it's a god on it's own account.

Water does not decay.
