Examlex
Suppose we discovered radio signals coming from the star Alpha Centauri, whose distance is 4.4 light-years from us, and we sent a crew in a spacecraft to visit it. If the spacecraft used revolutionary technology allowing it to travel at a speed of 0.5 c, how long would it take the spacecraft to get to Alpha Centauri, and how long a time would the astronauts say passed during the trip? (Ignore the time it would take to accelerate the spacecraft to reach a velocity of 0.5
c.)
