where is the center of the universe

[Anonymous No.10320268]

>inb4 there is no center because it is expanding in every direction
how is this relevant? if i stretch rubber band it still has a center the whole time
the only way it has no center is, if it is infinite, so why not say that? why is the expansion always brought up?

[Anonymous No.10320276]

It has a center obviously, it's just not relevant because the universe is expanding everywhere and not away from a point
The center might even be outside our observable bubble

There is no physical center just as there are no borders; the universe is either (probably) infinite or curved spherically

>it's another thread where OP asks a question and then inb4's the actual answer
there literally is no center dumbass. the big bang happened EVERYWHERE, ALL AT ONCE. it characterizes a rapid, ACCELERATING expansion and whether or not there are "boundaries" to the universe is completely unknown dumbass and even if there are, in what form they are in, we don't know. the accelerating part is key because no matter where you are in the universe you appear to be in the center, and this has always been the case, because there is no real center

if you are imagining the big bang from the outside like a marble getting bigger then you are a dumb fucking idiot and should kill yourself. it happened everywhere that exists, and it's a retarded jaden smith-tier thing to then say "well what are we expanding into?????!/1?!?!?!?" nothing. the universe is defined to be "all existing matter and space as a whole"

what has this to do with the question if there is a center? a center is a center no matter if there is expansion going on or not

how do you respond to someone like this that clearly can't read?

>how would you know this if do dont even know if the universe is finite?
again, you can't fucking read. i already pointed out that there might be boundaries. but unless you are claiming that there is an impassable wall separating existence from non-existence, which is not what people mean when they say "finite universe", AND unless you are claiming that the universe is a perfect sphere (irregular shapes are not considered as having a center because there is unlikely to be any one point equally distant from the entire ""wall") then you are just fucking retard (protip you are retarded either way)

the rapid accelerating expansion happened everywhere, all at once. if you can't understand why this means that there is no center then you are both hopeless and retarded.

sure, bubble universes are a speculative idea, and in that case there would be domain walls out there, and a “center” of each particular bubble could be defined. but keep in mind this is only one out of ~10 different multiverse ideas, and most of them don’t work like this. in the many-worlds multiverse, for example, the universes are “parallel” in that history evolves into multiple copies but not spatially separated. bubble universe theories like eternal inflation are regarded as highly speculative; OTOH in the “standard model of cosmology” [lambdaCDM] there is no center and no domain walls. heck, even in eternal inflation, the entire shebang of all bubble universes and the inflationary field between them all started at the big bang which happened everywhere, and domain walls formed later

In the balloon analogy the universe isn't the entire balloon. The universe is just the surface of the balloon so there's no real center. The center of the entire balloon isn't on the surface, so I guess the center of the universe isn't within the universe.

if it's finite then sure it has a center of mass, but there will almost certainly be no way to ever prove this by the very nature of having an accelerating expansion. there's already a horizon around us whereby light past that point can no longer reach us

Laws of physics are translationally invariant under a spatial translation if they do not distinguish different points in space. According to Noether's theorem, space translational symmetry of a physical system is equivalent to the momentum conservation law.

if we assume that there is a center, then the universe is no longer symmetric under transformation, and that would contradict conservation of momentum, there is no center of the universe, the end.

No that's not even close to what I said. The objective universe is much larger than the observable universe. If you went to the edge of the universe by instant transmission you'd see a different part of the universe expanding uniformly around you not unlike what you'd see from earth because the universe is homogenous and isotropic.

Nobody here has any visual reasoning ability.
Pretend the universe is a 2d surface (the skin of a balloon). It inflates. All points move away from the center of the balloon, and the distance between them increases. But the center of the balloon is a 3d point that is not on the surface of the balloon.
Therefore, the layman explanation is that the center of the universe is outside of the universe. Confusing, yes, but it's the only solution. The center of our universe is a 4d point outside of our 3d universe.
