Modern oldies

The anomalies in cosmology are proliferating and I do not have enough time to write TGD explanations for all of them although I do my best. I received very interesting link to findings challenging the standard beliefs about the formation of stars.

The standard story about formation of stars goes as follows. Nuclear fusion at the cores of stars produced the elements. In the first stars only light elements were formed and spewed out in supernova explosion to get gathered to the stars of next generation able to produce heavier elements. The elements heavier than Fe were not produced in stellar interiors since this was not energetically possible. One would expect that in very early Universe in which only few generations of stars had been present, the interstellar clouds would contain only light elements.

This story can be compared to empirical facts by observing quasars emitting light with huge intensity coming from cosmic gas clouds. The light from quasars reveals their chemical composition via absorption lines. The researches (Eduardo Banados, Michael Rauch and Tom Cooper) were able to identify 13 billion year old cosmic clouds formed 850 million years after Big Bang and study their spectroscopy. The work is publish in The Astrophysical Journal (see this).

The surprising finding was that the abundances of elements look very modern, they are very much like those in the cosmic clouds formed several billion years later. The conclusion is that the first generation of stars formed more quickly than believed and were already expired before the formation of the cosmic clouds so that the clouds would consist of chemical products of much later star generations even before the galaxies were in place.

To me this interpretation does not look convincing. For me these findings represent a further challenge for nuclear physics as we believe it to be. Let us list some shortcoming of the standard nuclear physics first.

1. The formation of elements heavier than Fe is still poorly understood. No evidence for the R-process in supernovae was found to in the case of SN1987A. There is no generally accepted model for the production of elements heavier than Fe.

2. Even worse, nuclear fusion inside solar stars thought to be thoroughly understood, has a 10 year old anomaly. The abundances of elements are higher in the interior than they should be (see this). This is really serious anomaly and challenges the foundations of nuclear physics – in particular the idealization of nucleons with point like particles and use of potential models
   and the notion of tunnelling which is central for understanding nuclear fusion.
3. There is also “cold fusion” or LENR, which is a fact but still not admitted by the mainstream (see this and this). The essential aspects are production of heat energy and transmutations.

TGD based model of “cold fusion” leads also to a modification of standard view about what happens ordinary nuclear fusion. The mechanism of “cold fusion” relies on the formation of dark protons sequences at magnetic flux tubes giving rise to dark nuclei with much smaller nuclear binding energy. These decay spontaneously to ordinary nuclei and liberate almost all nuclear binding energy leading to the heating and transmutations.

1. The tunnelling is central element in ordinary nuclear fusion and is replaced by a new mechanism involving in an essential manner the geometrodynamics of space-time as a surface in M⁴×CP₂ and new view about quantum theory and dark matter residing at monopole magnetic flux tubes.

2. Besides ordinary nuclei also their dark variants as phases having effective Planck constant h_eff=n×h₀ are present in solar interior and contribute to the abundances.
3. The view about pre-stellar evolution changes. “Cold fusion” in near to the surface region of star precedes ordinary fusion and serves as “warmup band” heating the matter to temperatures of ordinary nuclear fusion.
4. “Cold fusion” as induced by dark fusion becomes an important contributor to the production of also heavier elements formed already before the hot fusion in the solar core has started. This mechanism works also outside stars and the elemental abundances could be almost universal having very little to do with the nuclear physics in the stellar interior.

The basic prediction is that the spectroscopic signatures for the star would not depend much on the generation of the star. Therefore also the spectroscopy of cosmic clouds would be almost independent of their age.
