String Theory

String theorists claim that the universe has 9, 10, 11, 13 or whatever number of dimensions (depending on which theorist you talk to). These claims are based on nothing more than mathematics, however, I wouldn’t be surprised to discover that the universe does indeed have more dimensions than the 4 dimensional space-time that Einstein’s general relativity implies.

It would seem to me that in order to have free will and a choice available to us to do this or that, then both options have to actually be available to us – otherwise we never really had a choice in the first place. Assuming we do make choices in our day-to-day actions, then the chain of events related to the option that we didn’t choose must also exist in the universe. For this to be true the universe should have more than the 4 dimensions implied by Einstein's general relativity. I suspect that without extra dimensions life experience would feel stale.
