Twin Paradox A thought experiment in which one twin (A) travels into space at nearly the speed of light and returns to find she has aged less than her sibling (B) who has remained on Earth. This result is paradoxical because of the

Bell inequality in which the twin photons possess neither definite energy (color) nor a definite time of emission prior to their detection. Moreover, nonlocality is further demonstrated by the fact that a change in the path length of one of the

so-called "spacetime paradoxes" such as the twin paradox , length contraction , time dilation , and so on. These paradoxes, in turn, expose the "relativity" of separate space or time measurements, but they point to an
