SH, much homage. Very little doubt that he was entheogenically catalyzed, at least in early theorizing. Hawking, essentially established the reality of "black holes". Early 20th cent physicist, K Schwarzchild, contemporary of Einstein, wrote the math on BHs. Simply, a mass compactification, such that, it's escape velocity is GREATER than light speed. Hence, EM radiation and classical particle matter are precluded from "leaving" the immediate vicinity, described by the, Schwarzchild Radius. An information sink.
Hawking taught us that not only do BHs exist, they indeed inform our universe and lend the structure to galaxies and supra-galactic architecture. They behave as gravitational wardens throughout! Beyond that he plyed, establishing that non-classically, BHs would and do "evaporate", according to quantum rules that allow, NON LOCAL, matter commingling. All well predicted by Einsteinian Relativity.
Exceedingly difficult to overstate his contribution to the, physical/metaphysical, matrix of understanding that forces a blending of rational AND irrational to more completely apperceive our REALITY reference frame!!!
Peace
