indeed, i think it would be more correct if i said the centre is nowhere (edgeless negatively curved space and whatnot) but i was already going with the centre theme :XD, which isnt too wrong, considering the big bang took place in every point of space
why do you say that we should be near the middle? were even nowhere near the biggest known supercluster. You can see 13billion+ years old galaxies in any direction.
Universe would have a defined centre, if the big bang was an explosion in a location of space, but it was an explosion OF space. Its like in its own little bubble, you cant reach the edge because its curved itself. An analogy is going around on earth: you keep walking on the basically 2dimensional ground without reaching an edge, because the ground is like wrapped around a 3dimensional sphere, the planet. the same could be if the universe (3dimensional :p) is wrapped around a 4dimensional hypersphere, which isnt the case since the universe is actually negatively curved.
We ARE exactly in the middle of the observable universe though, but thats purely observer-based.
Dont quote me on any of this though, im still only a low- physics student :D (who should be studying for an exam right now)
hey, at least it isn't quantum mechanics, where a single electron can go through two separate parallel holes at the same time, but only when you're not looking
I disagree that we're right in the center of the universe. Sure we're quite near the middle when vaguely talking about the center of the universe.
