What Relativity

What Relativity is

Due to the physicists do know neither the performance of light nor the Camila effect, when they want to explain the Relativity they think about time dilatation and contraction of space which is not a simple way to explain what relativity is.

The relativity of time is the mathematic relation of the time t₀, which a photon goes from a stopped light source on a determined position to a determined receiver, with the time t that a photon goes from a light source with velocity v on the same position to the same receiver.

This relation is expressed by the relativistic formula of time:

In this formula we will only use the value of modulus of v, independent of its direction.
