I think you raise a good parallel with Earth but I don't think it applies directly to the possibilities for a multiverse because we cannot see other universes but we can see other planets.
Imagine if our solar system was inside a nebula and the only star we could see was Sol. Until we figure a way to send a probe outside the nebula we have no idea if their are more stars or not. Do you see a way to "send a probe outside" and see if there are more universes or not?
- MrBingley 9y agoOff the top of my head I don't really remember, though Brian Greene does devote a whole chapter to the question of detecting other universes in his book, so that might be a good place to look further. At the moment though, this doesn't really bother me. For example, Giordano Bruno suggested the existence of exoplanets in 1584, and certainly he could not have predicted the modern techniques the Kepler telescope uses to detect them! It may be centuries before we have the theory or technology to determine if other universes are detectable or if they exist. A long time to wait perhaps, but this should not be a reason for ruling them out (though of course, solid evidence would be required before a multiverse theory could be accepted).
