Let me first say I appreciate the last week questions, regarding different kind of measurement more or less similar to the Michelson-Morley experiments
Finally I got some time to better explain how the new theory explain this..
It’s really a good question and very central to the new theory, what really happens with a photon that has entered the elastic ether following the Earth.
According to Einstein the speed of light is the same to all observers.
Several experiments confirm it. No doubt about this.
Here at the forum Reality Check, MRC Hans and me was about 5 years ago discussing whether the ruler also inside a gravitational field is a variant or not.
The answer is we don’t, but a simple thought experiment shows that this is the case.
‘A’ live in the basement of a skyscraper, ‘B’ at the top of the same building.
Both have measured the time it took a photon to travel 13 billion. from the very first star and to us..
But A’s clock (deeper in the gravitational field) is as we know ticking slower than B’s clock.
B would argue that it took the photon one minute longer to reach us – than the time A has measured. Simply because B’s clock is ticking faster than the A’s watch. The difference is probably in reality less, but it means nothing , its the same point.
We accept that the speed “c” is the same for both A and B.
When both A and B know the time and speed, A and B can only conclude that either the distance to the star that emitted photon is significantly different, which is utopian, because the universe is not likely to change shape depending on the observer who observes a process .
Otherwise, the conclusion can only be that A’s ruler (in the basement) must have changed (have streched longer) proportional to the time also have stretched, - as a result of A’s watch is deeper in the gravitational field.
Only in this way A and B both can assert that ‘c’ is the same for both (even thoug ‘c’ is not comparable the speed )
SR and GR is a theory of reality transformation, but the new understanding is that
everything is always either stretching or contracting
proportional, either due to gravity or relativistic speed..
This comprehends all the following factors;
- Distances
- Rulers
- Energy , Mass (increase or decrease)
- Any process
- The EM spectre
- The speed of light
- Time
A photon will, when it enter the gravitational field of the Earth, not feel the speed of the Earth , but only feel that the tension of space has changed, and due to that, the speed of light will change too, - so that the speed of light adapt to the new , tension of space, - or if you prefer, -to the new space time reality.
The common denominator causing all these proportional effects to happen - is the variation of tension of space, - or you can say the variation of the tension of the ether.
