Decay

[chilehed]

Black body radiation has never been observed outside of a cavity filled with soot or graphite....

“Black-body radiation is the thermal electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment, or emitted by a black body (an opaque and non-reflective body).

So much for the claim that those atoms who’s electrons are jumping up and down between energy states are in thermal equilibrium with its environment...... were they such they would not be gaining and loosing energy.

Yes, I am aware they have fooled most into thinking blackbody radiation is commonly seen, but it doesn’t exist in nature. Just in laboratories in little soot or graphite lined boxes.....

Wow. Just... wow.

Thermodynamic equilibrium doesn't mean that every single atom is at exactly the same temperature as every other atom. It means that the average temperature of the atoms in any region of the body is the same as the average temperature of all of the atoms in any other region.

You're constantly bathed in blackbody radiation - it emanates from everything around you, and it's detected every time it's looked for (provided you know how to look for it).
