Agree with Stinky....
dunno why anyone would get hung up on what the universe is expanding 'into'. I've always assumed it's expanding into nothing in particular. Seems to me that most of the universe is comprised of vast quantities of nothing, with occasional bits of something....
However, without wanting to aggravate any learned Astrophysicists out there, I'm very sceptical about many of the theories that have been evolving in this field for many years. Their very complexity smacks of people desperately trying to find 'answers' within the very confusing and contradictory observations that have been made over the years. I really can't comprehend string theories & multiple dimensions, dark energy/matter etc.
I find that E = Mc2 is much more elegant. I prefer to entertain the belief that eventually someone brilliant will stumble across an equally simple/complex & yet elegant unifying theory/formula to explain how it all works.
For example, if you look at the mathematical formula that generates a Mandelbrot Set, you will see that it appears relatively simple. But look at the absolutely incredible images it can generate, which it appears to do to an infinite level.
I think we are at the same sort of stage that Watson & Crick were before they finally hit on the correct structure for DNA. Did you ever see their first model of what they thought it looked like? You would laugh now, since we all know how symmetrical & elegant DNA actually looks, but then these pioneers persisted & finally figured it out. Maybe Astrophysics will be a similar situation.
But then, what the heck do I know about it? Nothing.... I'm the guy who thought that a 'quark' was the sound you get when you step on a duck....
