Flames Memes

Ever notice how movies portray blue flames as "cold" when physics is screaming internally? In reality, blue flames are the hottest part of a fire (around 2,600°F), while red flames are cooler (about 1,000°F). Blackbody radiation is physics' way of saying "the hotter something gets, the bluer its light becomes." Stars work the same way - red stars are cooler, blue stars are ready to melt your face off at 50,000°F. So next time you see a "freezing blue flame" in a movie, just remember SpongeBob's expression of existential terror. That's the appropriate response to such scientific blasphemy.
