I'm fulfilling my life-long dream of learning relativity theory by working through Taylor and Wheeler's Spacetime Physics. I've successfully made it through the first three chapters except for one problem, 1-10 on p. 23:
Samantha is beamed from Earth via a transporter to the planet Zircon (stationary with respect to the Earth) orbiting a star in the Andromeda Nebula, two million light-years from Earth. The time required for disassembling Samantha on Earth and reassembling her on Zircon is negligible as measured in the common rest frame of Transporter and Receiver.
Question: How much does Samantha age during her outward trip to Zircon?
Using the spacetime interval, the only (seemingly ridiculous) answer I can come up with is two million years. I would have guessed her to not have aged at all. I'm confused. Any help would be appreciated.
This is not homework. (I only wish I were back in school...)
