Speed of light

The speed of light cannot be exceeded.

 


Explanation

If you stand still your velocity is 0. There is a maximum speed that cannot be exceeded. That is the speed of light, and this amounts to approximately 300,000 km/sec. You write it with the letter c (latin: celeritas). There is something very special to that. Two light rays that hit each other, do not collide with the double speed of light. This is described in the special theory of relativity.

 


History

The German physicist Albert Einstein published the theory in 1905.
