Lost Time
None of our physical theories have ever employed a distinguished present. Until relativity theory, however, it was always easy to imagine taking some structure, treating it as the present, and then “animating” it so it flows. This chapter shows that buried within relativity there isn’t structure suitable for “animation” á la manifest time; there are not good relativistic candidates for a flowing now. An informal dilemma seems to hold: the better a structure represents manifest time, the “less” relativistic it is; the “more” relativistic it is, the worse it represents manifest time.
