studiot Posted April 4, 2017 Share Posted April 4, 2017 An interesting propositional experiment is as follows: A planet bound observer watches an astronaut approach and fly past in a spaceship at 0.8c relative velocity. The astronaut is holding straight out in front of her a 6 foot ruler, marked in feet. What will the planet observer see? Will he see all 6 foot markings? How long will he think the ruler is? If the astronaut rotates the ruler through a right angle as she passes What will the planet observer see happen to the ruler? Link to comment Share on other sites More sharing options...
