If you were to travel to a star 97 light-years from Earth at a speed of 2.30x10^8 m/s, what would you measure this distance to be? - (ly)
A.
Gamma (2.3e8 m/s) = 1.559
If the distance in Earth's reference frame is 97 ly, then the
distance in ship's refrence frame is 97 ly / 1.559 = 62.219 ly.

Light requires 4.5 years to travel from the nearest star to earth. If we could travel there in a spaceship going 90% of the speed of light, the trip would require 5.0 years according to clocks on earth. How much time would pass for the passengers in the ship?
