Our planet rotates around a star, our sun alongside the solar

>Assuming there are actually several other Universes, do they rotate too?
Depends first on if the bulk actually exists.

You'd also have to assume that the universes existed in some extra space to be able to move. There's no reason to expect something like that

>>8137806
why

>Assuming there are actually several other simulations

Fixed

>>8137809
Because the universe already contains everything that exists by definition.

To imagine our universe as floating around in "special" space with other universes, we would no longer be able to treat our universe as a closed system and our entire cosmological model would be invalid. At that point, the universe wouldn't be a universe anymore and the question becomes moot.

it could remain closed if its somekind of bubble that just rotates, just like in beer

In order for the universe to exhibit motion, it would have to be moving with respect to something else. As soon as you acknowledge this, you have to consider energy transfer in this system, which is not possible.

What if proof for the universe having angular momentum can be found in the symmetry breaking observation that identical particles possess different energies due to their spin direction (i.e left handed spin electrons possess 'weak hypercharge'). If the universe had a non-zero angular momentum, then particles that spun with the rotation of the the universe would seem to go slower relative to us observers, and vice versa for the other direction, thus creating the effect we observe.
Side note: A possible reason why the universe has angular momentum could be due to our universe being the inside of a spinning blackhole.

You don't know what you're talking about https://en.wikipedia.org/wiki/G%C3%B6del_metric

sorta related... why does out solar system, and planets/galaxies/... rotate in planes?

It's called a "multiverse" and it's not that special a concept, snowflake.

I never said the universe couldn't have angular momentum. Op was asking about translational motion, and there is no model which that exists in.

>>8137925
Multiverse from m or brane theory do not include spatial separation of parallel universes. At least not in the sense that op imagines, so I wanted to be as clear as possible that the universe isn't just floating around with a bunch of other universes.

Wave function doesn't collapse into a single outcome.

You know what this means. You've doubted it as long as you've been aware of its existence, but it's the ultimate state of our reality.

You're alone, in your quantum universe, same as all the rest of us you'll never truly meet.

Hi, hello, from an entirely different reality. :-)

>>8137791

if you added up all the speeds, how fast are we moving? is there any relevant time dilation from this speed?
