In
this supposed paradox, one of two twins
travels at near the speed of light to a distant
star and returns to the earth. Relativity
dictates that when he comes back, he is
younger than his identical twin brother.
The paradox lies in the question “Why is the
traveling brother younger?” Special relativity
tells us that an observed clock, traveling at a
high speed past an observer, appears to run
more slowly

Since relativity says that there is no
absolute motion, wouldn?t the brother
traveling to the star also see his brother?s
clock on the earth move more slowly? If this
were the case, wouldn?t they both be the
same age? When the
paradox is addressed, it is usually done so
only briefly, by saying that the one who feels
the acceleration is the one who is younger at
the end of the trip. Hence, the brother who
travels to the star is younger.
