Multiple Choice

Has relatively ever been tested?

A) No, because it would require us to set up physics experiments in faraway galaxies.
B) Yes, because even ordinary motion in automobiles and airplanes produces easily noticeable effects predicted by relativity.
C) No, because no one has been able to think of experiments that are able to measure the small differences between the predictions of Newtonian physics and relativity.
D) Yes, because (for example) subatomic particles can be accelerated to speeds approaching that of light.
E) No, because the theory of relativity contains paradoxes and contradictions, like the twin paradox.
