You are riding in a spaceship that has no windows or other means for you to observe or measure what is outside. You wish to determine if the ship is stopped or moving at constant velocity. What should you do?
A) You can determine if the ship is moving by determining the apparent velocity of light. B) You can determine if the ship is moving by checking your precision time piece. If its running slow, the ship is moving. C) You can determine if the ship is moving either by determining the apparent velocity of light or by checking your precision time piece. If its running slow, the ship is moving. D) You should give up because you have taken on an impossible task.
