Been thinking about the multiverse.
if there are other universes outside ours do they exist in the same ‘space’? Was there a series of big bangs creating individual universes made of galaxies,much like galaxies are clusters of stars? If they came from different big bangs will they have different physical laws? Can they have different physical laws if they share the same space? Will any of them be old enough for the light to reach us and let us see them? If the physical laws are different will they even emit light or something which we could see? If we can’t detect it somehow how can we tell there aren’t universes all over the place,maybe overlapping ours?
If we have gone from a solar system, to a galaxy to universe to a multiverse in such a short time, what’s next? Is the multiverse one of many?
My brain isn’t quite up to this!
