I think I see what you are getting at and while the concept is intruiging the logic is a little flawed. What you have are two different frames of
reference - the traveler and the one on earth.
If 10 years pass for the traveler, yes on his return to earth he will be younger than the twin he left behind. Just as an example lets say that 15
years passed for the earthbound twin, so in essence the traveler is now 5 years younger. However the traveler has not efectively extended his life in
any way... he has experienced 10 years of life during his travels and is now 10 years older. He does not really gain 5 years, he simply returns to the
earthbound frame of reference to find that he has missed everything that occured during those 5 years.
The traveler will still live out his normal allotment of years, he will just live them out a little later in the earths frame of reference than his
There is quite alot of info out there on this if you'd care to look, just google 'Twin Paradox'.
