This could well be the case, but I think that it's been over-accepted
based on the reputations on Einstein and Hawking. I've just been
reading more for my latest energy-related thread and I notice that
Einstein's "greatest blunder", the cosmological constant which first
was, then wasn't, and now may be again, was actually partly interpreted
by Einstein as involving another blunder - namely, his failure to
predict an expanding Universe, which he made a trek to Mt. Wilson to
admit that Hubble (of the observatory there) had beat him to it. I
don't think that Einstein was infallible, and although he was
undoubtedly a Creative Genius, he made more mistakes than Paul Dirac,
Steven Weinberg, Pierre De Fermat, Sir Isaac Newton, or even
Plato/Socrates, Ricci, Levi-Civita, Riemann, Gauss, Euler, who were all
Creative Geniuses. As for Hawking, he is well on his way to making
more mistakes than Einstein with less positive achievements
proportionately. I have a suspicion that Sir Roger Penrose is the
better Creative Genius of the Penrose-Hawking collaboration although he
also has been bogged down in twistors and a rather poor collaboration
with Hameroff of Arizona on consciousness and microtubules, and it
would be interesting (although not decisive) to know what Sir Roger
thinks of the expanding 4 sphere.
