I need this literally explained like I’m 5, well actually 4. My 4 year old is asking what a “solar flare” is.
In: 3
The sun is really, really big. It has a lot of mass. Gravity pulls stuff with mass together. With all that mass, the gravity inside is big enough to squish the hydrogen atoms together into helium. This is nuclear fusion and creates a lot of energy. The energy from this fusion pushes outward, contending with the force of gravity trying to pull everything inward.
