Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.
I’d like them to look for repeats of galaxies. Galaxies that may be the same but slightly different or in different parts of the universe. If the universe was its own black hole we might see like a sort of kaleidoscope effect
I believe that would be a Torus-shaped universe that could produce that effect, basically a donut where space loops back in on itself. I think it’s something that’s been considered, though it sounds as if there’s no evidence for or against that idea, and it’s not considered likely.
The trouble with that is the difference in time. Since the light has to travel such a vast distance, multiple images of the same galaxy will show different stages of maturity. Even the stars will have been recycled.
