Is gravity a particle field on spacetime or is it the geometry encoded in spacetime itself?
Since strings is 10-11 D, does a mass-energy object curve all 10 dimensions of spacetime or only 4 dimensions?
Is there a problem of time in string theory as there is in canonical quantum gravity? What is the relation between the timelessness of the Wheeler-deWitt equation as a theory of quantum gravity and string theory quantum gravity?
When string theorist speak of the unification of the 4 forces, unifying gravity with the electro-strong, does that include unifying spacetime?
