Textbook Problem

If you use an Earth-based telescope to project a laser beam onto the Moon, you can move the spot across the Moon's surface at a velocity greater than the speed of light. Does this Violate modern relativity? (Note that light is being sent from the Earth to the Moon, not across the surface of the Moon.)

To determine

Whether the modern relativity will be violated or not when a spot is moved across the Moon's surface at a velocity greater than the speed of light.

Explanation

Introduction:

Modern relativity concept have two postulates. First postulate states that system works in inertial frame of reference and second postulate states that velocity of light is independent of medium. It is same everywhere.

Theory of relativity is not violated because laser beam are not having mass and beam travel above the speed of light...
