For as long as humans have looked skyward, they have called the Sun a ball of fire — a metaphor so intuitive it hardened into assumption. Yet the Sun does not burn in any chemical sense; it fuses, converting hydrogen into helium and mass into energy at a scale that dwarfs all combustion, powered by nuclear physics rather than oxygen. The material it is made of — plasma, the fourth state of matter — is not an exotic curiosity but the dominant form of visible matter in the cosmos, comprising more than 99 percent of what exists. To correct this misconception is not merely to update a fact, but to
