Quentin from Switzerland said if the universe had a closed spherical shape could one of the galaxies in the sky be the Milky Way in its past state? Interesting. In principle the answer is yes but you also need to consider how large the universe is to understand whether or not one would be our own galaxy that we're seeing in our sky. We don't see any evidence that that the observable universe in all the light we can see from starting close to the big bang with things like the cosmic microwave background. There are other closed geometries like Tori and different- I don't know what a Tori is. It's the pool of tourists dude. Yeah a tourist. That's it
