Chapter 33, Problem 30P
You’re the communications officer on a fast spaceship that takes 50 years in ship time to reach the Andromeda Galaxy, 2 million light years from Earth in the common rest frame of Earth and Andromeda. As soon as you reach Andromeda, your captain orders you to send a radio message to Earth announcing your arrival: he claims the message will reach Earth about a century after you left. You claim it will be much later when the message arrives. Who’s right?

Suppose we want to send an astronaut on a round trip to visit a star that is 200 light-years distant and at rest
with respect to Earth. The life support systems on the spacecraft enable the astronaut to survive at most 20
years. At what speed must the astronaut travel to make the round trip in 20 years of spacecraft time?
Your clocks and calendars are synchronized with the clocks and calendars in a star system exactly 10 ly from earth that is at rest relative to the earth. You receive a TV transmission from the star system that shows a date and time display. The date it shows is June 17, 2050. When you glance over at your own wall calendar, what date does it show?
Albert Abraham Michelson became the first American to win the Nobel Prize in Physics in 1907 for his work on improved measurements of the speed of light. If his descendants wanted to leave Earth and travel to a star 300 light-years from Earth to receive a radio transmission sent in 1907 announcing his award, how could they do so?
a)Travel in a ship in which the proper time is less than 300 years.
b)Travel in a ship in which the proper time is more than 300 years.
c)They could not - it would require travelling faster than light, which is impossible.
d)Launch a rocket which leaves Earth at 99.99% of the speed of light, then launch a second stage from the rocket, which moves away from the first stage at 99.99% of the speed of light.

What is the relative velocity of the two spaceships in units of c? Hint: keep in mind that the two spaceships are approaching each other. Round your answer to three decimal places.

- The starship Enterprise is passing the planet Vondor when it is discovered that a Klingon spy has planted a bomb on board the ship. Mr. Spock has determined that the bomb will explode in one day (in the ship's frame). It can be defused only by the galaxy's leading bomb expert, who is at Star Base 23. Star Base 23 is at rest relative to Vondor, and a distance of seven light days away from Vondor. (A light day is the distance traveled by light in one day.) Captain Kirk orders the ship to head towards Star Base 23 at maximum speed. Scotty is repairing the warp drive engines, so only the impulse engines (maximum speed 0.99c) are working. The ship already is moving towards Star Base 23 at a speed of 0.99c, so it just continues with that constant velocity. Will the Enterprise make it to Star Base 23 before the bomb explodes?
