Hubble Redshift: New Paper on Its Implications

    Redshift
In summary, the conversation discusses a new paper on the Hubble redshift and its relation to the energy of a freely moving photon in General Relativity. The author makes two statements that are unclear and asks for clarification. The first statement discusses the change in energy of a photon as it follows a path, and the second statement mentions the rotation of space and its effect on the photon's energy. The conversation ends with a comparison between the acceleration of an object falling from a height and the acceleration of a photon, leading to a gain in energy and frequency. The concept of isotropic geodesics is also briefly mentioned.

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...
 

FAQ: Hubble Redshift: New Paper on Its Implications

What is the Hubble Redshift?

The Hubble Redshift is a phenomenon observed by astronomer Edwin Hubble in the 1920s, where light from distant galaxies appears to be shifted towards the red end of the light spectrum. This phenomenon is caused by the expansion of the universe, which stretches the wavelengths of light as it travels through space.

What is the new paper about?

The new paper on Hubble Redshift explores the implications of recent observations that suggest the rate of expansion of the universe may be accelerating. This contradicts previous theories and could have significant implications for our understanding of the universe's evolution.

How does this new paper affect our understanding of the universe?

If the observations suggesting an accelerating expansion of the universe are confirmed, it would challenge the current understanding of the universe's composition and evolution. It would also require a re-evaluation of the fundamental principles of cosmology and potentially lead to new theories about the nature of the universe.

What evidence supports the claims made in the new paper?

The new paper draws on data from a variety of sources, including observations of supernovae and measurements of cosmic microwave background radiation. These observations suggest that the universe is expanding at an increasing rate, which is consistent with the theory proposed in the paper.

What are the potential implications of the new findings?

If the new findings are validated, it could have significant implications for our understanding of the universe, including the nature of dark energy and the fate of the universe. It could also open up new avenues for research and lead to a better understanding of the fundamental laws governing the universe.
