Black Body Radiation
The hotter you are the more you radiate light. This is why we say “she’s Hot”.
Humans emit light. On the higher stratas of humanity, if you’re spiritually high you shine or radiate.
Human beings emit infra-red light. That is the reason in infrared light, people glow.
Black Body Spectra
Blue is hot than red.
White is hot than blue.
I believe Black is hotter than white. though we can’t see black light. Is Dark Matter black light. Has this been proved scientifically?
