Update to gravity

At the moment, I am considering what happens to Particles and light as they propagate through the medium. What seems to be happening is that particles lose frequency and light gains frequency. So the two effects seems to be cancelling each other out. This agrees with the idea of time dilation. However I intend to study this in more detail before I publish the results.

Schoolboy error

Light also loses frequency on board the spaceship.  With the gamma factor of 2, a 1 MHz radio frequency on board the spaceship, would translate to 2 MHz for the earthbound Observer.  So the frequency on board the spaceship is lower than it is for the Earthbound Observer.  I was assuming that the frequency on board the spaceship had increased to 2 MHz, but in reality it is the 2 MHz frequency, that has reduced to 1 MHz.

The medium exists

I am now convinced that this medium exists.  Particles propagate through the medium.  Time dilation and length contraction are simply due to the change of frequency and wavelength.
