The universe and repetition theory?
Discussion
My wife has just come back from a science lecture and is asking me all these tricky questions about the universe and planets.
Is it just me who is mad, or does this make sense to anyone else?
Surely if the universe in infinate, it therefore goes on for ever and ever. If this is the case at some point in time you are going to come across an identical dimension to the one you are now in. Where everything is exactly the same as the place you have left.
Does this sound nonsense, or just simple common sense?

not necessarily, there are an infinite number of real numbers, and they are all different, likewise you could in principle have an infinite number of universes with none of them being exactly the same. Is it just me who is mad, or does this make sense to anyone else?

Why does it have to be different dimenion, with the same stuff? It could be like going for a walk in the countryside. You don;'t see the same trees becuse you have gone a long way? There could, and in my mind should, just be more stuff out there. There is, of course the theory that the universe is vast, and infinite, but our own big bang could be a localised event. There could be other universes, that have had their own big bang expansion... Who knows.

I think this is the main point of theories.Everyone can speculate until the cows come home, but I think some things will be near impossible to get 100% correct.

My collection of half remembered maths ends about there!
The universe may or may not be infinite, but most probably doesn't have have an infinite amount of matter in it.
You can't really think of it in terms of 'places to visit' either, since it will almost certainly be impossible to ever travel from one 'side' of the universe to the other.

My understanding was that infinite in the case of the universe was just a way to describe the curvature of space time. if you keep going in a straight line in theory you will come back to the same point eventually because of curved space time. I think that's what Stephen Hawking said anyway. Unless I'm missing something the universe couldn't be truly infinite if it emerged from a big bang as it would have to have a starting point and a wave front of expansion. If it has an 'edge' then it can't be infinite.

Look for "a universe from nothing" on YouTube. I'd link to it, but in the airport on my iPod*I'm more than happy to be corrected on any or all of the above!
