Travel to the stars requires hundreds or thousands of years, even at the speed of
light. Some people have suggested that we can get around this difficulty by
accelerating the rocket (and its astronauts) to very high speeds so that they will age
less due to time dilation. The fly in this ointment is that it takes a great deal of
energy to do this. Suppose you want to go to the immense red giant Betelgeuse,
which is about 500 light-years avway. You plan to travel at constant speed in a
1000 kg rocket ship (a little over a ton), which, in reality, is far too small for this
purpose.
