starship-design: re: Twin Paradox

/However, the Twin non-Paradox would still happen even if one twin stayed
/on a fast-moving spaceship while the other took a relativistic jaunt in
/the ship's shuttlecraft; the one who left and came back on the
/shuttlecraft would be younger.


	Could you point me toward a little more info on this phenomenon? 
Are we referring to biological twins, or 'twins' as in equivalent beings
coexisting in parallel universes?
