"But now this deflection is not in physical space but in branchial space. The fundamental underlying mathematical structure is the same in both cases. But the interpretation in terms of traditional physics is different. And in what to me is a singularly beautiful result of our models it turns out that what gives the Einstein equations in physical space gives the Feynman path integral in branchial space. Or in other words, quantum mechanics is the same as general relativity, except in branchial space rather than physical space."
Most of this stuff is mind-bending to me the same way statistical quantum mechanics, information theory or higher-dimensional physics are. But I always come away from reading about it with a feeling of "there could be something here, and I'm glad someone is exploring it further"
