Kip Thorne says (Lecture in 1993 Warping Spacetime, at Stephan Hawking's 60th birthday celebration, Cambridge, England,) Comments, interpretations, appreciated. I thought classical time was always symmetric ....apparently not. Is this same description applicable to a "big crunch" as well? Apparently Weyle curvature at the big bang and black holes seems to go to infinity while at the big crunch it's essentially zero....how does that relate to this "direction" of time??
