Re: What would you do if you could travel in time for one hour--into the past and into the future?

Yes, but an even more obvious and sort of vaguely plausible one is the
inertial frame at the event of departure. So if you go pastwards (in
such a way that you don't interact with matter), you emerge lofted into
space a bit, and futurewards you emerge buried in the mantle.

Um. Unless I've made a mento in my Visualization of the Geodesic All.
(no, not Buckminster Fuller; the *other* kind of geodesic...)
