The big bang theory, and others :)

[FPVSteve]

Nothing was there before the big bang. Space itself was compressed to the size of nothingness, nothing existed before that. There is no 'void' that the universe is 'expanding' into, the universe is the space it's expanding into.

into what?

Well, we're all simply a series of chemical reactions - what if it's already mapped out for us and we don't actually have freedom of choice due to chemical reactions which have, and will, because of the cascading chain of events, happen.

This is actually a strongly held theory by some people. We don't make 'conscious' free will decisions, what we do is act based on the chemicals in our brains / bodies, making us make the decisions we do....

And again, another theory is that if we could get over the Heisenberg uncertainty principle, and at the time of the instant of the big bang, work out the state of all matter then if we fully understood all physics we could extrapolate from that point, to where we are now, and past this and into our future, after all, atoms only follow laws of physics (albeit known or unknown laws).

Actually, I don't think of chaos theory as being 'random', rather I consider it a pattern that we can't see through not having a full understanding of the universe and physics of the universe.

into what?

You're thinking too three dimensionally. Into nothing, the universe is the space that the universe creates as it expands.

[FPVSteve]

What if the Universe isn't expanding, but something else is contracting, pulling us with it. Think like a wave when it crashes and starts pulling back into a foaming breaker (or crushing gravity well).

I like this thread - split it off? :D

I went to a Stephen Hawking lecture many years ago.
Someone asked him "If you could know, for certain, one single thing....what would it be?"
His reply....
Is the universe infinite?... No.
Will the universe expand forever and have a cold silent death?... No.
Does God exist?... No.
His answer was "The temperature of the universe ten to the minus thirty four seconds after the big bang"...
Jees. Different world...
10E-34 second ?
Light travels less than the diameter of an electron in that time - probably..
Strange people about.

Hehehe corrected :)

I preferred bag.
It added a certain je ne sais quoi...
LOL
