Let’s take a breath before diving in, because this part is n’t just another chapter about heat or light. This is the part where the Sun stops being a glowing sphere and becomes a living, shifting, changeable machine erected from glamorous forces so involved and important that they dominate nearly every miracle we’ve explored so far. What this really means is that the Sun’s captivation is n't a point. It’s the design. The hidden mastermind. The reason the Sun has spots, storms, eruptions, cycles, tempests, flares, and moods. The reason the nimbus burns hotter than it should.
