I think time is more of a torus.
I thought time was a cube?
Somehow that feels like song lyrics to me ...
Wibbly wobbly timey wimey
The Universe is locally flat.
And so is the Earth if you localize it enough.
you're telling me that parallel lines don't intersect, and angles in a triangle add up to 180°?
Does that rule out worm holes or just wrapping back around if you go far enough
It rules out gravity...
https://en.wikipedia.org/wiki/Flatness_problem
No, the best evidence we have today says the universe is flat.
It's a complicated topic, but Wikipedia sums it up pretty well.
Can't argue with that. Not like flat earthers think that mountains don't exist.
Damn, I love seeing comments where people change their mind with more info.
I TOO thought it had to be malarkey, and then got existentially panicked, and then read the proposed theories about why and am less existentially aware. Universe is big, man, weird shit, and now it's kind of in a pizza dough shape? Wild.
Never believed in gravity anyway.
Universe or galaxy?
The galaxy is a sphere!
Not ours. The milky way is a flat spiral. That's why it's a line in the sky (obviously the stars we see also belong to the milky way galaxy)
Sheeple!
I think this was a joke about flat earth?
Sure, but I was the joke is to point to something that in fact is flat
The universe is flat.
Most galaxies are semi-flat rotating discs of stars.
Only solid-ish objects like planets, stars, moons, and black holes are spheres.
3D-flat as opposed to 2D-flat, or a bigger, crazier theory?
It's just not carbonated.
Haha, and insert chest joke
You go up enough spacial dimensions and everything looks flat.
It seems awfully coincidental that, of all the curvatures out there, the universe should just end up having none.
It's flat, sure, except for all the wibbly-wobbly, timey-wimey stuff.
