This is one of the big theorys that I think realates to psionics, I just dont think anyone else had the thought to put them together. Quantum
mechanics, and General relitivity both explain String theory, and string theory is beginning to explain psionics and alternate demensions.
I think it would be helpful if you explained how you feel string theory and psionics are compatible, as I do not know exactly what you are getting
at. Maybe post a few links and be a little more in depth of your hypothesis.
