The Trouton-Rankine experiment failed to measure this phenomenon, which ironically gave additional credence to its existence. Terrell rotation is an illusion caused by this phenomenon. This phenomenon occurs counterintuitively in a paradox proposed by John Stuart Bell, where it only applies to one part of the setup. This phenomenon causes the circumference of a disk to produce contradictory values in Ehrenfest's paradox. On a Minkowski diagram, this phenomenon can be illustrated by comparing the space between points on the original position axis and the scaled position axis. In one thought experiment centering on this phenomenon, a moving pole either fits or doesn't fit inside a barn depending on which object's reference frame is considered. For 10 points, name this relativistic effect that causes an object size to change. ■END■
ANSWER: relativistic length contraction [or Lorentz contraction; or Lorentz-Fitzgerald contraction; or any answer of relativity causing an object's length to change before "change" is read; prompt on special relativity]
