Length Contraction

Length contraction is a fascinating effect predicted by <a href="/article/albert-einstein">Albert Einstein's</a> theory of special relativity, where an object moving at very high speeds appears shorter in its direction of motion to an observer who is not moving with it. This isn't a physical squishing, but a fundamental change in how space and time are perceived at speeds close to the speed of light. It's a key piece of the puzzle that shows our universe behaves differently than our everyday experience suggests.
