A new interaction is derived, which is important only when photons penetrate a hot, sparse electron plasma. When photons penetrate a cold and dense electron plasma, they lose energy through ionization and excitation, through Compton scattering on the individual electrons, and through Raman scattering on the plasma frequency. But when the plasma is very hot and has low density, such as in the solar corona, the photons lose energy also in a newly derived collective interaction with the electron plasma. The energy loss of a photon per electron is about equal to the product of the photon's energy and one half of the Compton cross section per electron. The energy loss (plasma redshift of the photons) consists of very small quanta, which are absorbed by the plasma and cause a significant heating. In the quiescent solar corona, this heating starts in the transition zone to the solar corona and is a major fraction of the coronal heating. Plasma redshift contributes also to the heating of the interstellar plasma, the galactic corona, and the intergalactic plasma. Plasma redshift explains the solar redshifts, the redshifts in the galactic corona, the cosmological redshifts, and the cosmic microwave background. The plasma redshift, when compared with experiments, shows that the photons' classical gravitational redshifts are reversed as the photons move from the Sun to the Earth. As seen from the Earth, a repulsion force acts on the photons. These findings lead to fundamental changes in the theory of general relativity and in our cosmological perspective.
The measurements of the absolute magnitudes and redshifts of supernovas Ia show that conventional physics, which includes plasma redshift, fully explains the observed magnitude-redshift relation of the supernovas. The only parameter that is required is the Hubble constant, which in principle can be measured independently. The contemporary theory of the expansion of the universe (Big Bang) requires in addition to the Hubble constant several adjustable parameters, such as an initial explosion, the dark matter parameter, and a time adjustable dark energy parameter for explaining the supernova Ia data. The contemporary Big Bang theory also requires time dilation of distant events as an inherent premise. The contention is usually that the light curves of distant supernovas show or even prove the time dilation. In the present article, we challenge this assertion. We document and show that the previously reported data in fact indicate that there is no time dilation. The data reported by Riess et al. in the Astrophysical Journal in June 2004 confirm the plasma redshift, the absence of time dilation, dark matter, and dark energy.
Let us consider an atom in the Sun. All frequencies of the atom, all the energy levels, and all the frequencies corresponding to the energy differences between two levels in the nucleus and in the atomic electron configuration are gravitationally redshifted, according to Einstein’s classical TGR, as seen by a distant observer in a coordinate system free of gravitational fields. As we bring that
atom from the Sun to the Earth, the gravitational redshifts of the frequencies disappear. During the travel of the atom from the Sun to the Earth the levels and the frequencies are blue shifted,and that blue shift cancels the gravitational redshift.

We explained that the photons’ frequencies are gravitationally redshifted in the Sun, but that the gravitational redshift is reversed as the photons move from the Sun to the Earth. This reversal or blue shift cancels the gravitational redshift

abandon well tested theories on the strength of one paper.
Yep, this is the 68-page paper I remember (we discussed it earlier, here in PF). Does anyone know if it was, in fact, published? If it was, all I can say is that its publication should be hailed by all those with left-field ideas as a great source of encouragement!ohwilleke said:Here is the foundational paper by the same author, also this year, the paper quoted above is a seven page corollary to the original:

-and this, from another source:Because of its lack of atmosphere, H1504+65 allowed researchers to use space-based Chandra X-ray observatory and Far Ultraviolet Spectroscopic Explorer (FUSE) telescope to determine its composition
Hard to see how plasma redshift explains why a WD with no atmosphere would have the highest apparent surface gravity of any star in its class.Detailed NLTE line profile fitting revealed that H1504+65 is the most massive PG 1159 star, having the highest surface gravity

3) "The photons are gravitationally redshifted when emitted in the Sun; but during their travel from the Sun to the Earth, they lose their gravitational redshift, and are not gravitationally redshifted when they arrive on the Earth"
I've not seen such a description before; is any reader aware of any experimental work that supports this (incredible?) claim?
( from “Red shift of photons penetrating a hot plasma” )The plasma-redshift theory, that is deduced in this article distinguishes itself from all the processes mentioned above. It is about the interaction of one incident photon with a great many electrons in the plasma. The theory for this scattering has never been dealt with before. The plasma redshift is related to double Compton scattering and multiple Compton scattering, but it distinguishes itself from these processes, because it is a new multiple scattering process on a great many electrons (not only one electron, as in double and multiple Compton scattering). Although incoherent, it is not related to Raman scattering or incoherent scattering on the plasma frequency.
The plasma redshift can usually be deduced using classical physics methods, but it requires quantum mechanics to derive the relevant damping.
Nereid said:Thanks Garth. I must have missed the 'no gravitational redshift' in SCC when I first read you paper (and focussed on the 'SCC predicts the same as GR ...' - not paying enough attention to the caveats - other than no DM, and GPB will show something different!).
So, if in SCC there's no gravitational redshift
a) what did Pound & Rebka find?
b) what about Sirius B (thanks turbo-1) and all the material Chronos posted (thanks Chronos), oh, and the X-ray line profiles from near SMBH (I posted that ... but the link is in a quite old post)?
Asteroseismic analysis is a technique used in astronomy to study the internal structure and properties of stars by analyzing their oscillations or "starquakes". This method involves studying the frequencies and patterns of these oscillations to determine the star's properties, such as its age, size, and composition.
The Kepler Data refers to the data collected by the Kepler space telescope, which was launched by NASA in 2009 with the goal of discovering Earth-like planets orbiting other stars. The telescope continuously monitored a specific region of the sky, measuring the brightness of over 100,000 stars, and providing a wealth of data for astronomers to study.
Asteroseismic analysis is useful because it allows scientists to study the internal structures and characteristics of stars, which provides valuable insights into their evolution and formation. This technique also helps in understanding the properties of exoplanets, such as their size, mass, and composition, by studying the effects of the star's oscillations on the planet's orbit.
Some of the main challenges in asteroseismic analysis of Kepler data include dealing with the large amount of data, as well as the complex and noisy signals from the stars. Scientists also face challenges in accurately modeling the stars and their oscillations, as well as interpreting the data to extract meaningful information.
Asteroseismic analysis of Kepler data has led to several exciting discoveries, including the detection of a "twin" of our Sun, the first exoplanet found to be within the habitable zone of its star, and the discovery of a planetary system with seven Earth-sized planets. This technique has also helped in determining the age and evolution of thousands of stars, providing valuable insights into the formation and history of our galaxy.
