8.1   THE EMISSION THEORY

The Emission Theory is consequence of applying directly Newton’s dynamics to light as particles with mass emitted by material objects. It proposes that the velocity of light is the constant c plus the velocity of the source of the light.

In vectors form:

ç = c + u

Without any convincing proof and with the rise of the Relativity Theory the Emission Theory was forgotten.

No variations in the speed of light have been experimentally detected until today.  Several reasons can cause this invariance.

One reason is that in nature the possible sources move two slowly to be detected.

Other one is that, as Emission Theory states, every photon acquires a new source velocity component (u) when they interacts with atoms ( the atoms of the mediums), even air atoms, then the original source velocity component is lost. An experiment in vacuum with a source of considerable velocity should be made.

Yet another one surges now due to the train structure of the light rays that reaches Earth after many years of travel. For example in the binary stars emission phenomena the train can be compressed in the half of the cycle and decompressed on the other half but the train can present a self accommodation of its photons and at large distances the train becomes uniform so no effect of the velocities of the stars is present at the final rays.

As Relativity Theory is wrong only the Emission Theory verifies Michelson-Morley experiment (Section 8.2).
