*At 49:42 he defines the metric tensor. It has a Kronecker delta as the leading term. So all cross terms will be zero in its matrix representation. Listen; this is pure mathematics. If what he calls the metric tensor is the general correction for curved spacetime, it can be proven mathematically, strictly by mathematics. What I see is a hand-waving argument at best!
