Essay

Suppose we discovered radio signals coming from the star Alpha Centauri, which 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 0.5c, how long would it take the spacecraft to get to Alpha Centauri, and how much time would the astronauts say passed during the trip? (Ignore the time it would take to accelerate the spacecraft to reach a velocity of 0.5c.)
