| Does the universe have a center?Or is it infinite and has no origin? What do you think? |
 |
| This is highly debated but the universe does not have a center, it depends on what you think but I think the universe is infinite. Nobody really knows the truth about this. It really depends on what you believe and know to make your inference on this. |

| I wasn't reading nor going in deep with astronomy to be sure but if the light/universe after big bang spreads to all directions in the same constant speed than the epicenter of that explosion should be the center of the whole universe, I wrote if it has the constant speed as I recall hearing/reading somewhere that the speed of universe expanding is decreasing tho I am not sure for that information. Besides that I also think that the center of galaxies/some galaxies are the black holes, no idea if it's the case for every galaxy - than maybe the theory/idea of the biggest/largest black hole in whole universe might be in the center of universe? |
| Having a center would require a spacial boundary, but there's no proof yet that the universe has such a boundary. |

| I guess it depends what you mean by center. If the universe is infinite spacially then obviously it doesnt. But for example, maybe space goes on forever but the actual matter that we can find in the universe is denser around some point and gets sparser as you move away from that point. Even if the universe is infinite, in this case you could maybe define a "centre" for the universe (e.g. the centre of gravity of the universe) much in the same way we assign convergent infinite series a value. If you ask me, one thing that is worth considering is that "distance" is relative to the speed of the measurer, in particular, at relativistic speeds distances shrink from your perspective. Apparently if you could go exactly at the speed of light, the whole universe would be squished onto a single point (but it is impossible for anything with mass to reach the speed of light since that would require infinite energy). I don't know if you can really draw any conclusions from this but to me it seems like maybe from a certain point of view on a cosmological scale the question of "what is the centre of the universe" is somewhat ill defined. |
| Laymen should be banned from discussing scientific topics. It is possible to define a notion of centre of mass in certain infinite universes, so unboundedness has little to do with this question... Zarutaku said: Having a center would require a spacial boundary, but there's no proof yet that the universe has such a boundary. Another senseless claim. A possible construction (that works in a natural class of asymptotically flat spaces) uses a foliation by constant mean curvature surfaces (say M(t), t>0) that is unique at infinity. The centre of the universe is then given by the limit (you have to prove that it exists of course) of the centre of gravity of the leaf M(t) as the parameter t diverge to infinity. |
| I am actually blind to this topic and almost never or want to question myself about this, since my life already has lots of problems, mainly health problem. But I would try to answer this anyway (a layman answer): Geometric wise: If the center means where the universe begins, and now keep expanding, it has to expand exactly at the same rate in every direction such that it is circle, and thus the center would still be the center with respect to the perimeter of the expanded universe. Which I think perhaps would be unlikely. If the universe is expanded in different rate in every direction, and that rate might change as well, then at one direction would be more expanded relative to other directions with respect to the center point. But then that center point is not the center point anymore, because different shape has different centroid, and in this case, the center point would change every incremental second depending on the expanded form the universe takes at that particular second. But if it's not about geometry, but simply the origin. Then I think there is, but it is difficult perhaps to trace where it was. |

| Isn't the universe continuously expanding? So it keeps on moving i think |
| The center of the universe is obviously [REDACTED]. |
| Nobody knows, the physicists are just making up bullshit theories to pretend like they're doing the humanity a favor. Everything the physics could have solved, we've already solved. The rest is impossible to solve and we're wasting resources. |
| no one knows heck google why modern science thinks the universe is flat |
| The center is where the observer is when they look out into space. The universe may be many orders of magnitude bigger than it is today, but not enough time has passed to see if that's the case, nor can we prove it due to the speed of light being the limiting factor. If the universe appears to be the same size when on another planet 10 billion light years away, then it doesn't matter where you are in the universe, you are in the center of the observable universe because the particle horizon remains the same (due to Hubble expansion). |

| Incredibly enough it's centred exactly on my anus. I'm afraid I don't understand the reasons myself but I can assure you that it's the truth. |
 |
| if your egoistic then you are the center of the universe as the saying goes |
| I am the center of the universe. No, really...I'm not just being smug. AI agrees with me. hehe "According to current cosmological understanding, every point in space can be considered the "center" of the universe because the universe is expanding uniformly in all directions, meaning there is no single point that can be defined as the center; from any point in the universe, it will appear as if everything is moving away from you equally. Key points to remember: No central point: The Big Bang is not visualized as an explosion from a single point in space, but rather as the expansion of space itself, happening everywhere at once. Uniform expansion: As the universe expands, the distance between any two points in space increases proportionally, making it seem like every point is the center. Observational evidence: This concept is supported by astronomical observations, which show that galaxies are moving away from each other at speeds proportional to their distance, regardless of our location." In other words, the center is everywhere or nowhere, depending on how you think about it.

| @Meusnier But defining that centre would require to know the centre of gravity you mentioned, and that would require to know the location of all mass and energy, right? Assuming there's a finite amount, wouldn't that imply there's a border beyond which no mass and energy is located? |

| @Meusnier So a folation can apply to an infinitely large structure? Seems kind of abstract. |

FlareBitz5 said: if the big bang is true that implies that there is an origin point of everything somewhere but looking at it everything is literally based on perspective because the center of the universe always appears to be centered on the point of reference See my post above with links to technical details. The big bang was not an explosion from a point in space expanding into pre-existing space, but rather a uniform expansion of space itself from a singularity that contained all space and matter. (At least in the sense of this universe, without getting into the idea of other universes.) https://www.space.com/25126-big-bang-theory.html "Although the Big Bang is often described as an "explosion", that's a misleading image. In an explosion, fragments are flung out from a central point into a pre-existing space. If you were at the central point, you'd see all the fragments moving away from you at roughly the same speed. But the Big Bang wasn't like that. It was an expansion of space itself – a concept that comes out of Einstein's equations of general relativity but has no counterpart in the classical physics of everyday life. It means that all the distances in the universe are stretching out at the same rate. Any two galaxies separated by distance X are receding from each other at the same speed, while a galaxy at distance 2X recedes at twice that speed." https://www.britannica.com/story/was-the-big-bang-actually-an-explosion "If the universe didn’t explode into existence, where did it all come from? According to the theory, the universe—this includes all space, time, energy, etc.—was condensed into an extremely hot zero-volume entity of infinite density called a singularity. In physics density is quantified by dividing mass by volume, meaning that the equation to determine the density of a singularity divides by zero. If that doesn’t hurt your brain, this will: Because all of space and time existed within the singularity, the singularity itself did not exist within space or time. The universe as we know it (or barely know it) is the result of this singularity expanding and cooling. Since the singularity itself was not in a location on the planes of space or time, there is no center of the universe; everything is expanding from everything else at an equal rate. As for the origins of the singularity, or even what existed before it, scientists are just as befuddled as everyone else." |

| I'm flattered to see there's more serious answers than ironic egotistical ones lol |
  |
| Well it all expanded from the big bang so a single point in space was originally the focal point of the universe. Not sure if any physical parameters could possibly upset that but point being, it's not illogical to think that there is one. I mean, the other consideration is that the universe actually does have bulbous sections like a piece of flubber, and naturally I wouldn't disbelieve that. Still, a center can be found. Wait... this is dumb... there's like a center to any shape, right? Um yeah, the universe is supposed to be in a shpae. |
