Dopplerian Redshifts: Alternative Cosmological Paradigm?

In summary, the author discusses the possibility that the basic cosmological conjecture about the Dopplerian nature of redshifts may be false due to interactions of photons with gravitons. This could have implications for interpreting supernovae 1a data and may require a change in the standard cosmological paradigm. Additionally, the author suggests that the existence of black holes may contradict the equivalence principle and proposes a connection between Hubble's and Newton's constants. Theoretical values for the Hubble constant are also computed. Overall, the paper presents a fringe but interesting perspective on cosmology.

If gravitons are super-strong interacting particles and the low-temperature graviton background exists, the basic cosmological conjecture about the Dopplerian nature of redshifts may be false: a full magnitude of cosmological redshift would be caused by interactions of photons with gravitons. Non-forehead collisions with gravitons will lead to a very specific additional relaxation of any photonic flux that gives a possibility of another interpretation of supernovae 1a data - without any kinematics. These facts may implicate a necessity to change the standard cosmological paradigm. Some features of a new paradigm are discussed. In a frame of this model, every observer has two different cosmological horizons. One of them is defined by maximum existing temperatures of remote sources - by big enough distances, all of them will be masked with the CMB radiation. Another, and much smaller, one depends on their maximum luminosity - the luminosity distance increases with a redshift much quickly than the geometrical one.
If the considered quantum mechanism of classical gravity is realized in the nature, than an existence of black holes contradicts to the equivalence principle. In this approach, the two fundamental constants - Hubble's and Newton's ones - should be connected between themselves. The theoretical value of the Hubble constant is computed. Also, every massive body would be decelerated due to collisions with gravitons that may be connected with the Pioneer 10 anomaly.

I was looking at that one today. It's fringe, but interesting.

I agree, i posted it as a curiosity, i read it a couple of times but could
decide on how fringe it is.
 

1. What is Dopplerian Redshift?

Dopplerian Redshift is a phenomenon where light from distant objects, such as galaxies, appears to have longer wavelengths than expected. This is caused by the expansion of the universe, as the space between the object and the observer stretches, causing the light waves to also stretch and appear redder.

2. How is Dopplerian Redshift different from the traditional model of the expanding universe?

The traditional model of the expanding universe, known as the Big Bang Theory, explains the redshift of light as the result of the Doppler effect caused by the objects moving away from each other. However, the Alternative Cosmological Paradigm suggests that the redshift is instead caused by the stretching of space itself, not the movement of objects.

3. What evidence supports the Alternative Cosmological Paradigm?

One piece of evidence is the observation of unusual redshift patterns in galaxies, where the redshift varies within the same galaxy. This is difficult to explain with the traditional model but can be explained by the stretching of space in the Alternative Cosmological Paradigm. Other evidence includes the observed distribution of galaxy clusters and the acceleration of cosmic expansion.

4. How does the Alternative Cosmological Paradigm explain the age of the universe?

The Alternative Cosmological Paradigm suggests that the universe has always been expanding and has no beginning or end. This means that the concept of the age of the universe is not applicable in this model. Instead, the universe is in a constant state of expansion, with no specific starting point.

5. What implications does the Alternative Cosmological Paradigm have on our understanding of the universe?

The Alternative Cosmological Paradigm challenges the traditional view of the universe and offers a different explanation for the observed redshift of light from distant objects. It also has implications on the concept of the beginning and end of the universe, and our understanding of the expansion of space and time. Further research and evidence are needed to fully understand the implications of this paradigm on our understanding of the universe.
