From my understanding this is String Theory: The Purpose of String Theory is to provide a unification between the forces of Gravity and Electromagnetism Every atom is made up of tiny vibrating strands of energy called strings These may be circular (closed ends) or linear (open ends) The Standard Model has three forces (Electromagnetism, Strong nuclear force, and weak nuclear force). that are explained by messenger particles. Einstein's laws say that the fabric of space can stretch or warp but the could not rip. But string Theorists say that it can rip, which would mean that wormholes are possible. Which would make teleportation possible. Ed Witten modified the theory and it has come to be known as "M-Theory" To make sense, M-Theory would need 11 dimensions, 1 dimension of time, and 10 dimensions of space; instead of 1 dimension of time, and 3 dimensions of space. Dimensions all have to do with the independent directions in which something can move. (degrees of freedom) The extra dimension that Witten added allows these strings to strech into membranes, and according to string theory the univers that we live in is on one membrane, and they think that there are many parallel membranes with different universes on them. String theory calculations predict that matter cannot escape from one membrane onto the other, but gravitons can. So theoretically we could be able to communicate with other universes with gravity signals. The problems with it is that there is no way to really test it.
