Sun tunnel effect?
Hello folks.
The sun has extremely high temperatures (5 million ⁰C) and high pressure.
It is said that only nuclear fusion takes place in the sun because these values are so extreme.
But are these values sufficient for nuclei to fuse in the sun at all?
Or is any fusion only possible through the tunneling effect, which occurs when there is a low probability of positive hydrogen nuclei repelling each other?
MY QUESTION:
If the heat (kinetic energy) of the nuclei in the sun is sufficient to overcome the potential barrier that arises because like-charged hydrogen nuclei repel each other, and the fusion rate is further increased by the tunnel effect,
Or
Is the heat and pressure of the sun not enough to make fusion possible at all, and is the tunneling effect necessary for every fusion in the sun?
(If the second is correct, we would have learned it incorrectly or inaccurately/simplified in school)

also room temperature and normal pressure are theoretically sufficient to allow two protons to fuse.
because the speeds of the particles in a gas follow a distribution, which shifts more to higher speeds for higher temperatures, but always allows speeds which are as small and as large as desired.
at room temperature it is very rare that two protons meet with enough energy, but impossible it is not.
the question would therefore be much more whether the probability and thus the frequentity for such a reaction under the conditions in a star are sufficient to maintain a stable fusion which causes sufficient heat development and counteracts the gravity pressure.
and the answer is: without the tunnel effect (which also allows the fusion for two protons which do not completely overcome the coulomb barrier, and thus the overall probability would be significantly increased).
So the tunnel effect is not a prerequisite for a fusion in itself, but for a stable in our measure.
So nuclear fusion would also occur in the sun without the tunnel effect, but much too rarely to generate the light and heat energy we need?
The tunnel effect in a star is only possible by lower pressure and the high temperature.

This has not answered my question
The same question you asked
I don’t understand what additional knowledge you’re hoping for.
The Angelsaxon calls the “lies to children”. Of course, only sas was taught at school, for which there is also the necessary equipment.
I would like to know whether the values in the sun are sufficient for a fusion, and the fusion rate is increased with the tunnel effect, or whether the values are not enough, and 0 mergers take place, but only through the tunnel effect.
