Interesting fact, the sun is terrible at fusion. Think about it, why hasn't the sun just instantly ignited all its fuel, and blow up all the milky way? The limiting factor infusion for the sun is one, heat, and two beta decays. The first you likely knew, but beta decay, "whatchu talking about Willis?" I'm quoting Arnold from one of my favorites shows growing up called Different Strokes. Well, when you smash two hydrogen atoms together, you get what we call a di-proton. It is sometimes called Helium-two, and boy does it not like existing.

És ekkor a rendszer finom, olajozott kerekei közé por, autóroncsok, enzimes mosópor került. Recsegés, ropogás, füst és korom. Mi történt?
