Comparing the standard view and TGD vision of the formation of astrophysical objects

I learned of a very interesting empirical finding (see this) related to the attempts to understand the process leading to the formation of light molecules H₂ and HD from atoms. According to the standard view, this process precedes the ignition of the nuclear fusion made possible by gravitational condensation. This process is not so well-understood as one might think and the findings challenge the prevailing view.

The gravitational collapse leading to the formation of a star requires low temperature and large enough mass. In the formation of first stars, HeH⁺ molecules act as coolants of the gas cloud. In standard view, this helps to reach gravitational instability inducing a gravitational collapse leading to the formation of a star and initiation of nuclear fusion. The surprise was that the rate for the reactions removing the coolant does not decrease with temperature as expected. This finding challenges the prevailing view about the formation of the first generation stars and inspired the comparison of the standard view of the formation of galaxies, stars and planets with the TGD view.

See the article Comparing the standard view and TGD vision of the formation of astrophysical objects or the chapter About the recent TGD based view concerning cosmology and astrophysics.
