      Not as far as we know… but it probably very difficult to detect other universes… they are… well other universes!

      But, one possibility I have heard off is that the force of gravity may be much much weaker than the other three forces because it ‘leaks’ out of our universe (whereas the others propagate only within our universe). If this really is the case then you might imagine that if the ‘distance’ to a neighbouring universe was changing the force of gravity might also change a bit (since it would interact with this ‘other universe’ differently if it was ‘further away’)

      But, this is all very speculative…

      Hi Zander, not that anyone seems to know about, but no-one can prove there isn’t either, so who knows?
