According to modern scientific theories, the physical universe has no edge or barrier, it loops back in on itself, so if you go far enough, you'll end up back where you started from.

Yes it's to do with how the Galaxies are moving apart they appear on a curve or bubble which itself is expanding. It's still only a theory.
It's a known fact that the Universe is expanding exponentially, so if this theory is correct, eventually the Universe would expand to such a degree that it would collide with itself where it first started.
hmm

The problem with that analysis is that nothing says the universe had to start anywhere.
Originally posted by Symmetric ChaosWell to put it in another way, if this theory is accurate, the Universe would collide with itself from the point where it initially started expanding.

Because the Universe had to have began expanding somewhere.

Actually we don't know that 😬
And even if we did is still wouldn't bump into itself.

The Universe used to be much smaller, now it is much bigger..... It started from somewhere.

No quite.
If you take a balloon and suck all the air out of it and then then inflate it again there is not point that it part of the balloon where the expansion began.

Mainly since it has a limitless quantum vaccum into which it can expand. The only thing that would cause trouble would be if it fell back in on itself (due to the mass inside) or froze (due to there being too much space)
Originally posted by Endless MikeI understand that, but there was unquestionably point(s) of expansion...
The universe didn't begin expanding somewhere, it began expanding everywhere.It's just at the Big Bang, "everywhere" was confined to a very small space, and then it expanded. There was no one place where it started.
Any one of these near infinite ammount of points is where the Universe would collide with itself, if this theory is correct.

Originally posted by Symmetric ChaosWhat it sounds like this theory is saying, is that if something travels in one or any direction in this Universe, it will eventually end up where it first started.

I don't see how this would be any different for an expanding Universe.
(I do think that theory is BS though)...

Only if you're a sperate object traveling on the balloon's surface.

Every point in space is moving away from every other point in space not toward it
Originally posted by Symmetric ChaosAgain, this theory makes it seem as though the Universe itself is almost a sperical shape, so if something travels in one direction for long enough, it would eventually come back to it's starting point.

I have no clue as to the specifics of this theory, that's just my general impression.
Originally posted by Endless MikeIf you're viewing the Universe as a Sphereical shape, eventually something expanding within this sphere would meet with itself at some point.
There is no nipple, that's just an analogy.Think of it as an expanding sphere (even though it's higher dimensional than that)
What is expanding is spacetime itself, all of it at once. Every galactic cluster is moving slowly away from every other one.
Unless it expands infinitely of course

Its much more complex than spherical. But when compared to the universe itself every object within it is one dimension lower and in a closed system.
Imagine a line going in a circle.
Imagine a triangle sliding along a sphere.
Imagine a 3D space ship moving in an equivalent manner though 4D or higher space.
😬 Its an odd theory but it does work for the most part.
[edit] I see what you're saying now. The reason it doesn't bump into itself is that points that are part of the balloon don't act the same way as points traveling on it.
