The Problem With Quantitizing Einstein's Theory

The problem with quantitizing einsteins theory is that all these stringy vibrations started entering the dynamics before you got to the plank energy. And polcinsky de brains fixes that by cranking the string energy up to the plankEnergy, and actually make it even bigger than a the plank Energy. Then what you find is that one of the deep rains that you thought was a heavy excitation gets lighter and lighter. So there's never a regime in streng theory where the coupling is the the inter action strength, you know, large. It can at most be order one. When you sort of dial around in the strength of interactionns a different objects become light.
