starship-design: Re: The "So-called" Twin Paradox

Hi Rex,

I had wondered why you had not continued the discussion about the Twin
Paradox, since I know your ideas which did not agree with what was written
in Steve (VanDevender)'s last letter from 11/29.

Probably one can always "trick" someone in a local environment. So to find
the symmetry breaking factor in the Twin Paradox you *need* to look at a
global (non-homogeneous) environment.

This is why it is called "relativity", this word almost inherently means
comparison between global points.
