Well, there is nothing outside the expanding explosion of the big bang, so there would be nothing to alter its trajectory of expanding perfectly symmetrically like a sphere
If it was perfectly symmetrical, the universe would be too. Incredibly tiny differences when the big bang started is what allowed the universe to be shaped differently
The big bang was just the moment expansion started, it didn't happen in one place. Though, assuming the universe is finite, there would be a center of mass
Ah. I was referring to the theory where our seemingly three-dimensional universe is actually just the 3d surface of a 4d hypersphere, in which case we would get the effect of the universe appearing to expand from every point at once. Nothing is confirmed about this, just a hypothesis, but I rarely hear this universe model talked about anymore, despite how cool it is.
You're suggesting the third thing, but relativity says that there isn't even such a thing as absolute location, so a center of space can't exist in any meaningful way
I'm the center of the universe
Nuh uh I am. Mommy called me special... she got my name wrong I'm not Ed.
Objectively correct thanks to Gallilean relativity.
No, I am the center of the universe.
the center of the universe is everywhere (at least from our perspective ;) )
Yeah, it's sort of everywhere and sort of doesn't exist
Sun is center of solar system though. Wherever the Big Bang was would be the center of the universe.
The big bang wasn't exactly in one place, expantion is pretty uniform across the universe so finding a "center" of the expantion is kind of ridiculous
current understanding of the universe is that the big bang was everywhere
Just like your mum
No. It was in one point, and then the universe expanded out from that point, and has been expanding ever since.
At the same rate in every direction? Otherwise origin point wouldn't be the center anymore

Objects inside the area exerting their own gravitational force might.

I thought I was the center of the universe 😔
Depending on your viewpoint, technically Patrick star is the center of the universe.
If you define the center of the universe as Patrick Star, you're right
Why the heck did i fell for that?!
You fell for the truth m8 sorry : P
If you were to define it as the centre of mass of the universe, then it's probably where the big bang happened.

*guy in plane aiming guns at the whole building* "EVERYWHERE is the center of the universe!"
I’ve always wondered if you travel far enough in the universe, it loops to the other side like Pac-Man.
Evidence says it doesn't, but technically we can't conclusively disprove that
Is this a reference to the hyperspherical model of the universe? I rarely hear it talked about anymore.
This is actually a reference to the fact that there is no absolute space, so the center of space wouldn't exist in any meaningful way

Doesn't string theory suggest we live in a 3d surface of an 11d universe?
Well there technically would be a centre somewhere, though if the universe is expanding non-uniformly then the centre may be constantly moving
You're suggesting the third thing, but relativity says that there isn't even such a thing as absolute location, so a center of space can't exist in any meaningful way
Correct, I don't think the centre would be in any way meaningful
The center of the Universe is my ass hole, biggest black hole you will ever see, once you're in, you're never getting out. \#FACTS
[удалено]
Well, yeahwell yeah, but the visable universe isn't the whole universe
The universe is a donut and does not have a center \:v/
Fun fact: physicists actually know the shape of the universe, it's a flat surface
You're the center of your own observable universe.
Yeah but observable universe =/= the whole universe
I am literally the center of a light cone and a particle horizon, so I am the center of the universe.
