An astronaut is traveling at a high rate of speed from the Earth to a distant star system.Observers here on Earth note the relativistic effect that the astronaut's clocks run slow.What relativistic effect,if any,does the astronaut observe?
A)Her pulse rate slows.
B)The distance from the Earth to the star system has decreased.
C)Her clocks run faster.
D)There is no relativistic effect to be observed by the astronaut since she is the one doing the moving.

The astronaut observes length contraction, a relativistic effect where the distance between two points (in this case, from the Earth to the star system) appears shorter for an observer moving at a significant fraction of the speed of light relative to those points. This is a direct consequence of the principles of special relativity.
