Ives–Stilwell experimentt as explained by wikipedia:as folllows: " we assume that the speed of light is fixed with respect to the observer (“Classical Theory”), then the forward and rearward Doppler-shifted frequencies seen on a moving object will be f'/f = c/(c±v), where v is recession velocity. Under special relativity, the two frequencies will also include an additional “Lorentz factor” redshift component.
When we invert these relationships so that they relate to wavelengths rather than frequencies, “Classical Theory” predicts redshifted and blueshifted wavelength values of 1+v/c and 1-v/c, so if all three wavelengths (redshifted, blueshifted and original) are marked on a linear scale, according to Classical Theory the three marks should be perfectly evenly spaced.

But if the light is shifted by special relativity's predictions, the additional Lorentz offset means that the two outer marks will be offset in the same direction with respect to the central mark.

Ives and Stilwell found that there was a significant offset of the centre of gravity of the three marks, and therefore the Doppler relationship was not that of "Classical Theory".
This approach had two main advantages:
1.
didn't require us to commit to an exact value for the velocity involved (which might have been theory-dependent), and
2.
it didn't require an understanding or interpretation of angular aberration effects, as might have been required for the analysis of a "true" transverse test. A "true transverse test" has been run almost 40 years later, by Hasselkamp in 1979.[1] "
The vacuum density field is composed of negative electromagnetic energy and has the same characteristics of all electromagnetic fields. It has local regions of angular momentum, or where energy is "squeezed" when interacting with matter and light. Hence the Michelson-Morley experiment showed no "field" of light to travel through because of the "squeezing" affect on the atoms of the clock keeping time showing that all matter and time are light dependent. The clock composed of atoms slows down under te torsions of being compressed by the quantum density field.
Light travels at C through the vacuum density and matter at a faster rate of C. Matter that has double density of C2 travels at a slower rate because it can absorb in its angular momentum across its transversal axis, proportionality more energy before it must emit the excess at Planck rate.
It is also consistent with the Ives–Stilwell experiment because of this same “squeezing” affect due to angular momentum in local regions of space that is interacting with matter and light at the rate of Planck.
