The twin paradox shows that special relativity:
A) explains many things but can't explain everything
B) is accurate but contains some worrisome contradictions
C) is incorrect
D) only explains things in steady motion, but cannot be used to explain objects that accelerate
E) correctly accounts for the results of experiments in different reference frames

Quizplus · Accepted Answer

The twin paradox is often used to explain the effects of special relativity on objects in different reference frames. It shows that time dilation occurs when one twin travels at high speed to a distant location and returns, while the other twin stays on Earth. This effect has been confirmed by experiments and is a key prediction of special relativity. Therefore, choice E is the best answer.
