The uss enterprise is stranded at the center of the galaxy with a damaged warp drive, so it is limited to speeds of 0.9995c or less. the earth is 25,000 light years from the center of the galaxy. this measurement is what would be measured by an observer in an inertial reference frame at rest with respect to the center of the galaxy. express all answers below to 4 significant figures. if the enterprise heads towards earth at top speed: a) what distance to the earth in light years will be measured by spock, on board the enterprise? b) spock will observe the enterprise covering this distance at a speed of 0.9995c. how long (in years) will it take to arrive at earth as observed from the enterprise's reference frame? c) how long will observers on the earth measure for this trip? d) check your answer to b) us ing time dilation and considering the time interval between the enterprise leaving the center of the galaxy and arriving at earth.
