[ochzemto] Seemingly faster than light

Divide c by g and you get a length of time: 353.8 days.  I shall dub it the "Einsteinian year".

Mr. Newton sits on a spaceship with no windows and feels it undergo 1g acceleration.  He waits 354 days and concludes two things:

* He must now be traveling at the speed of light.
* 354 days have elapsed.

Both of these conclusions are wrong, sort of.

Does the Einsteinian year have any physical significance?
