Special relativity thingo explanation?
the thing is they don't...
that is, relativly speaking. Only when you travel back again, you'll notice that they will be older.
This is because time slows down the faster you travel. This has even been proofed IIRC, by sending an atomic clock to space and when it came back it was several thousands of a microsecond further.
Maybe explained wrongly... anyways, look up time dialation (another one of Einsteins subjects on Special Relativity)
