Textbook Question
Chapter 44.1, Problem 1AE
Suppose we could place a huge mirror 1 light-year away from us. What would we see in this mirror if it is facing us on Earth? When did it take place? (This might be called a “time machine.”)

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?
Imagine yourself as an astronaut being paid according to the time you spend traveling in space. You take a long voyage traveling at a speed near that of light. Upon your return to Earth, you’re asked how you’d like to be paid: To maximize your paycheck, which clock should you choose?
Group of answer choices
Either of the clocks should indicate the same time
It's hard to decide as the spaceship's speed is to be mentioned specifically in the problem.
According to the time elapsed on the spaceship's clock
According to the time elapsed on a clock on Earth
In 2030, the Australian Space Agency launches a spaceship to our nearest neighbour Alpha Centauri, approximately 4 lightyears
away.
According to a clock on Earth how long will the rocket take to get there if it travels at v=0.999c=299482km/s (where 'c' is the
speed of light equal to 299782km/s)?
About 2 years.
O About 6 years.
O About 4 years.
Zero time.
