Is the universe a curvature

[.:[Kazuma]:.]

It's always baffled me is the universe a large curvature or a long infinite void? Does it have beginning and a end. Or when you reach the edge you go return to your starting place?

As far as I know, the universe is a gigantic mass. On its edges are dark energy, which is supposedly what stretches it further. I assume if you tried to come in contact with the edges, you'd be destroyed, regardless of protection.

This is only what I've gathered, don't take my word for it. But the "beginning" according to the Big Bang theory (I think) is the center (assuming the universe was evenly stretched, which it probably isn't), and the "end" is the edges, the newly created space.

Fuck yes cosmological discussion.

Unfortunately, there's nothing much I can offer to the original topic because not even the experts are quite certain.

Dark Energy, if it exists, is everywhere, not just at the edges. And because Dark Energy pervades most if not all of space, it wouldn't destroy you. Maybe you're confused with Anti-Matter on that destructive part?

I'm talking about what stretches the universe. Isn't that dark energy? Maybe I'm confusing terms.

This thread just made me seem even more tiny and insignificant.

Dark Energy is the force that stretches the universe. But if it was at the edges, it would just push those along and nothing else. Dark Energy is all throughout the universe, which is what is send galaxies outwards.

Oh. I see. Maybe it has no end, then.

I've always thought of the universe being kind of a like a planet. There is no end of the world, it just goes on but it isn't infinitive. Meaning that if you go on at a starting point and you continue walking in one direction, you would eventually go back to your starting point without meeting an actual end.

But I do sometimes wonder about it more deeply than I feel I should. I even sometimes have this image in my head of touching the end of the universe as if it was wall. That's some other crazy stuff though.

Dark Energy is more of a factor in universe expansion... I'm not sure about a direct influence.

Whats anti-matter? Thats the only thing I dont know .

True, it's... More just a name for a single or several things that we can't fully explain that drive the expansion of the universe.

i thought of this as well. I actually used to think (i still do) that the
universe is just one of a collection of others, and anything outside
of that is impossible to cross. Thinking of it as a round planet has
precisely been a part of my thoughts as well. Just like a planet, you
could walk straight and eventually return to the point in which you
started at, that is if you could jump mountains and walk on water, but
i'm pretty sure it's obvious what i'm saying.

with sun's as big as the VY Canis Majoris, simply thinking of how
big the universe is could be....mind boggling

Bubble universes is a fun concept at its heart, but also currently close-to-impossible to prove or disprove, along with things that might happen should they collide (if they are able to).

Goddamn it, cosmology and i just had to miss it. Anyway, the shape of the universe is important in determining the ultimate fate of the universe since the finestructure constant depends on it. An infinite universe having a shape is unthinkable in just three dimensions so a sphere is insufficient, a klein-bottle is more appropriate, it involves a short detour through the fourth dimension without the need to break or interrupt the surface. Dark energy, great subject, but it's everywhere, the reason it is called dark, just like it's matter equivalent, is becauase it is unobserved. Where light, heat and kinetic energy (think of collision) are observable, dark energy and matter is not. There is not even an indication of dark energy and is only posed as to solve the problem of an accelerating expansion, something dark matter counters.

I don't think it should have to end, it might seem abstract but that doesn't mean it's not true. One thing is for sure, it's so damn big, we might never know.
