Where it all begins – Fusion in the sun’s core
I was wondering where this number 
comes from, and it turns out that what we observe is actually the light, neutrino and solar wind emitted by the sun, from which we deduce the power 
delivered by the sun, from which we deduce the mass the Sun needs to be burning to explain that power. It is, to me, a bit frustrating, as I’d rather think from cause to effect than from effect to necessary cause.
Solar wind
It would have been impossible for me to understand anything about this problem without Roland Grappin’s benevolent and enthusiastic help, thank you!
