D)All of the above

Question

Quizplus · Accepted Answer

A) Subatomic particles in accelerators exhibit effects of time dilation and mass increase at high speeds, which is in accordance with special relativity.
B) Light is always observed to travel at the same speed, which is a fundamental postulate of special relativity.
C) Time dilation can be observed in airplanes due to their high speeds relative to the Earth's surface.

Therefore, all of the above provide observational evidence that the theory of special relativity is correct.
