I'm glowing like a lightbulb, or a star, or a stone. And you are too. That's why heat vision cameras can pick you up, you're glowing in a part of the spectrum that we can't see. Most all objects do, and their temperature determines what colors and at what intensity they glow at. A toaster coil and an orange star have more in common than you think.
@starwall thats so cool
@jaybeanstalk It's why blankets work!
A prominent exception is almost all the lights we use in our homes these days. They look white without being hot because they're using non-thermal methods to produce photons, and in some cases they also use phosphors to absorb the light and re-emit it at more useful wavelengths.
@anne This is true, I actually considered this before posting but thought that "light bulb" would specify it more as a filament lightbulb. That distinction is important though and really paints the difference in efficiency between emission vs thermal light sources in our daily lives.
@starwall Well and as a radio/X-ray/gamma-ray astronomer the idea that most things are black bodies offended me :). Even stars in the visible have very important absorption/emission lines
A cool and chill place for cool and chill people.
