The author makes two statements I'm not at all clear about...can anyone explain??

In General Relativity, the change of the energy of a freely
moving photon should be the solution to the scalar equation
of isotropic geodesics, which is also known as the equation
of energy and manifests the work produced on the photon
being moved along the path.

What work is being done on a freely moving photon?



...the linear velocity ...of the rotation of space (due to the non-holonomity of it),

What does rotating space mean?...I thought there was rather convincing evidence our universe is not rotating...

I'll try on this one;
Just like dropping an object from a 100Km tower, the speed at first is slow,
After falling 100Km it will have much more Kinetic Energy.
The fall contributed “work” to boost that energy though acceleration to a higher speed.

Consider the photon that follows the same path; already moving at "c" with some energy.
Shouldn’t it also accelerate to a higher “speed” and energy?
Looking at the photon at the bottom we see it follows the rule of no change in speed, it is still only going at “c”.
However on closer inspection we also notice it has changed color to bluer!
That is a gain in Energy to a higher frequency;
the same “fall” has contributed the same amount of “work” to boost the energy of the photon.

Hope you see the common ground here.
 
Under the influence of gravity, I understand your explanation...

Am unsure what "isotrpic geodesics" imply...
 
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...

Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
