- A person puts in a 9.1 hr shift while travelling on a spaceship. An observer on Earth determines that the time spent was actually 11.8 hr. At what percent of the speed of light was the spaceship moving?Imagine an alien spaceship traveling so fast that it crosses our galaxy (whose rest diameter is 100,000 ly) in only 100 y of spaceship time. Observers at rest in the galaxy would say that this was possible because the ship's speed B was so close to 1 that the proper time it measured between its entry into and departure from the galaxy was much shorter than the galaxy frame coordinate time (~ 100,000 y) between those events. But how does this look to the aliens? To them, their clocks are running normallu, but the galaxy, which moves backward relative to them at speed B~1, is Lorentz-contracted to a bit less than 100 ly across: this is what makes it possible for the whole galaxy to fly by them in only 100 y. Then find the diameter of the galaxy in the aliens' frame, and verify that it is possible for a galaxy moving at speed B with this diameter to passthe aliens' ship completely in 100y. Answer: 0.9999995how people arrived with the speed of light as of today explain
- A spaceship leaves Earth on a one-way star trip that earthbound observers judge will take 25 years. If the ship travels at 0.95c rela- tive to Earth, how long will the trip take as judged by observers in the ship?Relativistic effects such as time dilation and length contraction are present for cars and airplanes. Why do these effects seem strange to us?Is it possible in principle for a human being who has a life expectancy of 70 years to make a round-trip journey to a part of the universe thousands of light-years distant? Explain.
