A weird science thread.

Quote:

IIRC all bodies with a temperature of above 0K emit visible light to some degree.

or is it just black bodies?

2nd EDIT: **** you for that glowing personality ****.

This visible light differs from the infrared radiation - an invisible form of light - that comes from body heat

1000 times less power than the resolution of the human eye would be pretty small. I wouldn't be surprised if the visible band of the blackbody radiation from a human is comparable.

Assuming an emissivity of 1 (gonna be less than that), the visible power density would be on the order of ~0.1 W/m^2. Your eyes should be able to see 100 W/m^2.

I know I know, but isn't a small part of the spectra ( on part with what was posted ) Vis?

Spectroscopy and ****... I loved you all once....

EDIT: fricking beaten by Ramo.

Thanks for explaining blackbody radiation to me!

However, you should be experienced enough by now to read between the lines of bad science journalism. The journalist is trying to get across that this isn't simple blackbody ****, and he mentions fluorescence in the skin later on.
