I would like to make sure my interpretation of special relativity is correct. Is the following valid? An astronaut is traveling away from Earth at 95% of light speed. She turns on a headlight in the nose of the space ship. Question 1: How fast does she measure the light traveling from the headlight? Question 2: How fast is the light from the headlight traveling away from the Earth? Answer to question 1: c. Answer to question 2: c. This apparent paradox is due to the fact that distance and time are distorted in a reference frame that is moving with respect to another reference frame. Earth would see the clocks on the spaceship running slow, and the distances contracted, so that light seems to creep slowly from the headlight at 5% of c, but moving at c with respect to the Earth. Similarly, the astronaut would see the clocks on Earth running slower than her clock, and the speed of light would appear sluggish, but with respect to the spaceship it would have a velocity of c.
