Generation

Length contraction means that objects moving relative to you appear shorter along their direction of motion. If you could watch a spaceship zoom past at near light-speed, you'd measure it as physically compressed compared to its length when at rest—not just an optical illusion, but a real consequence of how space and time are interconnected. Crucially, astronauts *inside* the ship wouldn't notice anything strange about their own ship, but they would measure *your* ruler as contracted. This reciprocal effect occurs because measurements of space depend on your reference frame, and neither perspective is more "correct" than the other.
