I’m not sure how you jumped to that conclusion from the spherical analogy. But the B-theory suggests that absent an absolute universal “time T,” your measured intervals of time between events will vary relative to another observer who is in a different location or moving at a different rate or experiencing different gravitation (or acceleration), etc. Therefore, thinking of a set of all time segments prior to your “time T” may have subjective value, but it doesn’t have objective value. If all observational perspectives throughout the universe differ (whether slightly or significantly) and all are equally valid as Relativity would suggest, then how do you limit the number of temporal perspectives? In other words, considering all possible subjective reference frames based upon location, velocity, acceleration, mass, scale, direction, etc., what’s to limit the total number of time slices from all possible observational perspectives to a finite set?
