How does fire emit light (the sun, a candle, a fire, etc.)?
In: Physics
The sun isn’t on fire.
Other answers have explained that hot things glow with visible light. But the sun is hot because there is nuclear fusion going on, not because it is burning because it isn’t.
Everything emits light.
Hot things produce visible light. Cold things emit lower energy radio waves that can’t be picked up by human eyes.
Everything emits light. The light is different colors depending on its temperature.
If something is ~~too hot or~~ too cold, then the color of light it emits is not a color our eyes can see. But if it is just hot enough, the light it emits is a color we can see.

Scrolling through reddit, read the question.. “yeaah.. how tf does that happen”
Click.
Sun is not fire, it is plasma and would better be described as continuous hydrogen bomb explosion. But there is not burning taking place so its not fire.
Lol your “source” confirms what i said. It moves at the speed of light in a vacuum–a vacuum. I don’t understand how you earned a degree when basic concepts are so easily eluded; do you have a wikipedia source for that too? Or are you an internet troll that lies about sources and accomplishments?
IUPAC is my source, and I’m surprised you haven’t referenced any academically accredited source/institution, which leads me to believe you don’t have a degree, or you’re just a C- student with a lot of ego.
Do yourself a favour and keep studying if you want to be taken seriously.
