Now, after thinking this over, I'm pretty sure I'm wrong on this (rescinds bet). I think I wrongly concluded that a falling or orbiting frame is in an inertial frame. This must be wrong as you can determine that you are falling from tidal forces or the acceleration between bodies dependent on their location within your space. objects at the center of the gravity well would also experience a tidal force in all directions.

I am right about the twins paradox though.
