"Invisible visible" matter identified

That 30 per cent of visible matter has remained invisible is not so well-known problem related to dark matter. It is now identified and assigned to the network of filaments in intergalactic space. Reader can consult the popular article Researchers find last of universe’s missing ordinary matter. The article Observations of the missing baryons in the warm-hot intergalactic medium by Nicastro et al describes the finding at technical level. Note that warm-hot refers to the temperature range 10⁵-10⁶ K.

In TGD framework one can interpret the filament network as as a signature of flux tubes/cosmic string network to which one can assign dark matter and dark energy in TGD framework. The interpretation could be that the “invisible visible” matter emerges from cosmic string network as part of dark energy is transformed to ordinary matter. This is TGD variant of inflationary scenario with inflation vacuum energy replaced with cosmic strings/flux tubes carrying dark energy and matter. I must look look at the typical scales of the network to see whether this network indeed can be identified the cosmic string network containing galaxies along the strings as I dare bravely speculate;-).

This inspires more detailed speculations about pre-stellar physics according to TGD. The questions are following. What preceded the formation of stellar cores? What heated the matter to the needed temperatures? TGD inspired proposal is that it was dark nuclear physics. Dark nuclei with h_eff=n×h were formed first and these decayed to ordinary nuclei or dark nuclei with smaller value of h_eff=n×h and heated the matter so that ordinary nuclear fusion became possible.

1. The temperature of the recently detected missing baryonic matter is around 10⁶ K and roughly 1/10:th of the temperature 10⁷ K at solar core. This serves as a valuable guideline.

I already earlier realized that the temperature at solar core where fusion occurs happens to be same as the estimated temperature for the binding energy of dark nuclei identified as dark proton sequences with dark nucleon size equal to electron size. The estimate is obtained by scaling down the typical nuclear binding energy for low mass nuclei by the ratio 2^(-11) of sizes of ordinary and dark nuclear (electron/proton mass ratio, dark proton has same size as ordinary electron). This led to the idea that nuclear fusion at solar core creates first dark nuclei, which then decay to ordinary nuclei and liberate essentially all of nuclear binding energy. After that ordinary nuclear fusion at resulting high enough temperature would take the lead.

What about Earth? The temperature at Earth’s core is about 6,000 K. This corresponds to k=151. Could dark cold fusion take place also at Earth’s core. What is amusing that the earlier fractal analogy of Earth as cell would make sense in the sense that k=151 corresponds to the p-adic length scale of cell membrane.

If so then the standard views about the nuclear history of astrophysical objects stating that the material of stars comes from the material from supernovas would change radically. Even planetary cores might be formed by sequence of dark nuclear fusions ending with ordinary fusion? I have considered the possibility that dark nuclear fusion could have provided metabolic energy for prebiotic lifeforms in underground oceans of Earth and that life came to the surface in Cambrian explosion.
