You are in a spaceship with no windows, radios, or othermeans to check outside. How could you determine whetheryour spaceship is at rest or moving at constant velocity?(a) By determining the apparent velocity of light in thespaceship.(b) By checking your precision watch. If it’s running slow,then the ship is moving.(c) By measuring the lengths of objects in the spaceship. Ifthey are shortened, then the ship is moving.(d) Give up, because you can’t tell.
