The strange equation of quantum gravity
... general relativity allows us to compute the value of T1 when the second clock reads T2 , or viceversa. Does this describe the evolution of T1 in the “time” T2 , or, rather, the evolution of T2 in the “time” T1 ? The question is clearly pointless: general relativity describes the relative evolution o ...
