Ladder paradox

The Ladder Paradox is a thought experiment in the realm of special relativity that illustrates some of the counterintuitive consequences of relativistic effects, particularly time dilation and length contraction. It involves a ladder (or a pole) and a barn (or shed) scenario to illustrate how observers in different frames of reference can perceive the same events differently. ### The Scenario Imagine a long ladder and a barn that is shorter than the ladder when at rest.
