As I understand it, the time dilation will occur for the occupant of the
fast-moving ship, who will experience dilation relative to the stationery
observer. The traveler won't notice the slowing of time, since everything
in his frame of reference will likewise be slowed. As such, the stationery
observer is the one who will experience 20 years' worth of time.

| (...) Hi, let's do some math. IIRC T = t/(sqrt(1 - (v/c)^2) where T: time elpased for stationery observer t: time elapsed for moving observer v: velocity of moving observer c: speed of light assuming minimal acceleration.
