Hello. My question is based upon my (mis?)understanding of these two premises. 1. General Relativity breaks down when trying to describe the extreme conditions that are inferred to have existed in the very early universe. 2. According to this link... https://en.wikipedia.org/wiki/Semiclassical_gravity ...cosmic inflation isn't fully classical. So, does Semiclassical gravity also break down when trying to describe such extreme conditions? Or is that kind of extrapolation not within it's remit? Ok, that's two questions. Any help given or guidance offered would be appreciated. Thank you, Cerenkov.
