Another 1996 journal entry on relative motion

9/19/96

If you imagine yourself moving away from an event, then you imagine that light emitted by the event takes longer to "catch up" with you.

But, in the usual interpretation of relativity, you don't do that.  You may imagine someone else "moving away from an event" but not yourself!  No way, dude.  You (I) don't move; or really:  you move, I don't, which either you or I may say, knocking the requirement of stationarity (ho ha) back and forth between us.  The problem as I see it is: okay, you want only relative motion?  Fine!  But let me move, too!

Then, time of events does not become unique to me, however.  Is not unique, that is.
