SUN IS NOT ON FIRE
When some people picture the Sun, they imagine
something like a campfire or an object on fire.
But the Sun is actually a ball of gas. Every second
700 million tons of hydrogen gets converted into
695 million tons of helium. When this happens,
energy is released as gamma rays, which get
converted to light. So, the Sun emits light and
heat, but it's not on fire, because there's no
oxygen involved.
