A spaceship leaves our solar system at a constant speed of 0.920c and travels to a point in the Andromeda galaxy. According to astronomers in an inertial reference frame on Earth, the distance to the galaxy is 2.081 × 1022 m. What distance does the crew on the ship measure on its journey?
Thank you for the opportunity to help you with your question!
d'= 2.081 * 10^ 22 m
d = ?
gamma = 1/ Sqrt( 1-0.920^2) = 2.55
we know that d = d' / (gamma)
d = 2.081 * 10^ 22 / 2.55 = 8.155 x 10^21
