The elevator paradox is a paradox first noted by Marvin Stern and George Gamow, physicists who had offices on different floors of a multi-story building. Gamow, who had an office near the bottom of the building noticed that the first elevator to stop at his floor was most often going down, while Stern, who had an office near the top, noticed that the first elevator to stop at his floor was most often going up. This creates the false impression that elevator cars are more likely to be going in one direction than the other depending on which floor the observer is on. (Wikipedia).

Is Special Relativity Broken? ("Paradoxes" in Special Relativity: Train Paradox)
At first glance, it seems as though paradoxes, or contradictions, arise in special relativity. One of these is known as the train (or ladder) paradox and comes from the introduction of length contraction. As a train passes through a tunnel, the two reference frames (train's and tunnel's) e
