Do you believe the Universe is Infinite or Finite?

[ChrisMaster69]

I’m a Flat Universer

it’s like a flat Earther but bigger lol.

Seriously no one actually knows or even if it’s the only universe.

is the universe like a larger version of a galaxy

as we have billions of galaxies in our universe.

does our universe then sit inside a multiverse etc

[Cycloteur]

Its both in a way as its finit wrt. what an observer might discover from a given point and its infinite in that you. An never reach or observe an edge.
We grasp our existence in a mostly 3D way, hence there is no way for us to catch up with the expansion even with infinite time available to us as the expansion appears to be faster than c and we can only travel <<c and observe close to c.
The more you try and understand of this the less you really know as you realise that the true understanding is watly more complex and completely different than what you thought.
Its so much to do to make this earth a better place so I chose to focus here and not on whats out there. The smart people can do that instead.

We don’t know, although there are speculations. For example, we can mathematically estimate the size of our observable universe, which then allows us to speculate on the size of the “entire universe”. With this we know that there is a furthest point in one direction, but the Big Bang is simply the furthest by which we can go back in time. We don’t know if there was anything “before,” an existence that prevailed in a time before time.

According to data from telescopes visible universe ends 14,7 billion light years from our point of view in any direction. Therefore it ends.
It's possible that structures of dark mater and dark energy which interact with our baryonic matter due gravity are bigger and older, therefore our universe bubble is just a part of a much bigger one. However we can only speculate in this question.

[Sonorous]

I believe whatever Brian Cox believes.

[MCheetah]

Limiting things to just this universe and not bringing in the multiverse, I believe the universe is finite, since the universe is ever-expanding. This implies, there is an area to which it has not reached yet, and that may or may not be the "non-existence" limit point of the universe. Kind of like living inside a balloon that is inflating bigger and bigger.

[AviatorTom]

I believe the universe is infinite, but I have to explain what infinite means.

First off, infinite does not mean without end. The concept of infinity is actually quite simple. You give me a number, any number, the size of the universe for example. I'll add one to your number and call that infinity.

[TadCurious]

I have always wondered about this question. I don't have the scientific knowledge to really get my mind around the issue, but for me it's mindboggling. I do know that the astrophysicists tell us that the universe is expanding but my limited understanding is that it's as yet unknown whether the expansion will forever continue. I have heard it said that the universe has no edge and no center. But what exactly does that mean?

[Jersey2]

It’s finite but growing rapidly. It will either expand infinitely or it will collapse on itself. Perhaps all of the science loving atheists can tell us what is beyond the universe or perhaps what happened in the first instance of the Big Bang or even what happened before the universe was born… I won’t hold my breath.

[ODC2112]

I don't know. Define finite o infinte before. If is like in math where infinite is a big number (that in statistics is 30 for central limit theorem). If Big Bang theory is correct it is still in expansion. But we don't know what was the mass of primigenous nucleus that create the big bang. But, we don't know if it is correct and we don't know almost everything. If infinite is very big, yes it is infinite, but not indefinite.

[AllThatSweetJazz]

I want to say finite but infinitely expanding.
But I also feel like infinite and finite kind of break down at the limit of the "edge" of the universe. Like, I don't know what that's really supposed to mean out there.
One day I'd like to be able to dig into Einstein's astronomy work intuitively, but fuck if it doesn't seem like the least practical thing to spend time on.

[Likes2drive]

Infinite, there is no end to it , there is no wall at the end because what would be on the other side of it? Our brains are trained to think that there is always something inside of something or that there is an end but in reality there is nothing but just emptiness, problem I have is where did all the matter originate from to come to being here in our universe. Or are we all just in The Matrix?

[Jesuswasahue]

This isn't something anyone should have a belief about. No one knows. That is the only answer anyone should have. If you have any other answer, you are either an idiot or a genius like the world has ever seen, and if you like that last part, you're the idiot. lol

[Buntyp]

Apparently, it just won't stop expanding, so I'm going with infinite, unless, of course, it suddenly bumps into something and, not long after that, none of any of this matters--which will happen soon enough, anyway : )

[sensible27]

I never understood infinites. But an infinite universe feels off because well we can measure the speed sort of, given that there's a speed of expansion in big bang even if it's higher than light speed assuming the universe is infinite is just odd.

[LaFemmeFatale_1]

Probably infinite.

That being said, our problems seem so small when I remember the universe is so big.

[De_La_BakedBeans]

This is always confusing...
It's impossible for the universe to end...
But it's impossible for it to go on forever...
So what the actual f*ck is it supposed to do?

[purplepoppy]

I see it more as an ocean wrapped around an empty bubble. Movement within is infinite but it has a wobbly border.

[Neosporin]

The universe is finite but expanding indefinitely via dark energy expansion. What’s is it expanding into? Probably just some sort of higher dimensions who knows

[ChiTown33]

Well it's still expanding right? And speeding up. That would kind of make it infinite by definition right?
I guess it would depend what is outside the universe.

[tartaarsaus]

Finite but it is expanding, as that can be observed. Do we know how it is expanding? No. Do we know how fast it is expanding? Not really. But we know it is expanding

[Aerissa_Jade]

You mean if we go far enough in one direction we do not suddenly show up on the other side?

[slatyb]

Given that we're stuck on the surface of Earth, I don't worry about it.

[Alisa158]

People's cognition of unknown territory is limited, so subconsciously it is infinite.
