- A 50-year-old astronaut goes off on a long-term mission in a spacecraft that travels at speeds close to that of light. The mission lasts exactly 200 years as measured on Earth. Biologically speaking, at the end of the mission, the astronaut's age would be exactly 25 years none of the above exactly 30 years O less than 50 years the same as beforeSuppose a galaxy is moving away from Earth at a speed of 0.78c. It emits radio waves of 0.680 m. What wavelength would we detect on Earth? with a wavelengthA 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?
