The Sun converts hydrogen in to helium and then that gets converted into higher molecules. We know this from spectrophotometer observation of the sun.
The only direct evidence we have of hydrogen fusion in the Sun is the solar neutrino flux, and it’s famously problematical.
And what data are you using to compare the results found while using the spectrophotometer? Surely you are speculating that between here and the Sun there are no phenomena that could skew your results or perhaps you are speculating that there are no other gases or chemicals or ??? God only knows what that closely resembles the results junk-scientist claim to be fact isn't this correct?
Forgive me but I'm tired of egg-heads stating as fact "theories." Theories are nothing more than glorified hunches and until actual evidence (like a physical sample of the material burning on the Sun collected off the Sun) that's all this "hunch" will be.
I'd appreciate it if people would make their statements in an honest manner instead of trying to brainwash the general populace into supporting causes that are full of hot air.
