Do you or Do you not believe in the Big Bang theory. Was the universe created 15 billion years ago?

I've always had a problem of exactly what it is the universe is expanding into. I see it like a bubble growing larger in water. What is this "nothing" made of? Superstring theory suggests that the universe, instead of expanding into nothing, is actually converting nothing into universe. This does not exclude the big bang, it just changes the circumstances. There are anomilies with the BB theory as it stands, the shape of the universe for a start, which should, if BB is correct, be spherical which it isn't.

The Big Bang Theory is slowly creeping into more and more people's mind, which is a good thing. String theory will, I believe, answer questions we are now asking.

Why do people like you feel the need to be so gruff? If you have something to say, say it nicely or not at all.

I'm a fan of Big Bang theory but have a few reservations with regard to SuperString Theory. Mainly that experimentation to prove the existence of Strings hasn't been developed yet. That's not to say it won't be developed in the future but the amounts of energy needed to "uncover" these subatomic particles is staggering and there's not enough natural resources on this planet to build an atom smasher powerful enough or large enough to accomplish this. Still the unification of Relativity and Quantum Mechanics could well lie in the direction of SuperString Theory. Only time will tell I guess.

The problem with not believing the big bang theory is you have to then explain the 3 degree background radiation..



Anyway, for those people always asking what is it expanding into, let us just think about dimensions..

Imagine a 2 dimensional being, lets call him Stanley. (sic.) Now lets say that Stanley lives on the surface of a balloon, in essentially a 2 dimensional universe. If you as a three dimensional being start to inflate the balloon, Stanley can see that his universe is expanding, but being a 2-dimensional being, he cannot comprehend that his universe is expanding in 3 dimensions. He just knows it&#39;s getting bigger.

Now compare this to our universe of 3 dimensions, being 3 dimensional beings ourselves we have no way of comprehending what our universe is expanding into, we just know that it is getting bigger...

The big bang had a cause, or it could never had happened. That cause took place in pre-universe space. The universe is now expanding into whatever the universe expands into, if there was nothing to expand into, it could not expand. To say there was nothing before the big bang is ludicrous. There was no universe before the big bang, that should not be confused with there being nothing at all before it. Maybe you could explain that to Stanley.

lots of unanswered questions, why is everything expending faster than it should? is it anti gravity, is there a cosmological constant like Einstein first thought?

I also think string theory can/will solve most problems, but its more philosophy since it can&#39;t be proved right
