On the other hand, four or more spatial dimensions would mean that gravitational and electric forces would fall off faster than the inverse square law. In this situation, planets would not have stable orbits around their star, nor electrons have stable orbits around the nucleus of an atom. Thus intelligent life, at least as we know it, could exist only in four dimensions. I very much doubt we will find a non anthropic explanation.
They are assuming a universe with the same basic laws but just a different number of spatial dimensions. So yes, if you come up with totally different laws you might be able to imagine a 5D universe where life is possible.Gold Barz said:I still dont see why it is impossible, wouldnt a 5D universe have different laws than a 3D universe does? why do we apply our laws to their laws?
Somehow, I feel a strong inclination to bet that life occassionally arises in 4D anyway.Gold Barz said:So....it is improbable for life to arise in 4D+ universes...wow, that sucks majorly
