I think that if space itself is what is rotating, then speed of light limit does not apply. But if it’s everything in the universe orbiting, as it were, a central point, then it would.
But if it is space itself rotating, then that would suggest some objective frame of reference outside the universe. Wouldn’t it?
You might be onto something.
“It never occurred to me to think of space as the thing that was moving!”
But if it is space itself rotating, then that would suggest some objective frame of reference outside the universe. Wouldn’t it?
Not necessarily. Just like space is growing without the need for an objective outside frame of reference, it could be rotating - the rotation is just relative to itself.
I don’t think something can rotate relevant to itself. If all of reality was the earth, and nothing else, how can you tell if it’s spinning or not?
Please use small words if you try to answer this. I know a decent bit of applied physics, but once it turns to pure math, my head starts to swim.
