does cold radiate?

>> No.6148310

depending on the temperature i'd imagine it's an ever growing lack in radiation (assuming the system gets colder).


would there be a limit/ cap though?

>> No.6148325

Heat radiates to cold, so in a way yes.

>> No.6148358

All practical bodies radiate heat at all temperatures above 0K.

>> No.6148386

This is a stupid nonsense question. There is no such thing as "cold". Things only get "less hot" until they reach 0K. You do not use words like "radiate" and "cold" in the same sentence.

You're trying to get a scientific answer to an uneducated, mundane question. Cold does not radiate as cold doesn't exist. Heat constantly radiates. Duality is an illusion.

The only thing that matters is that when people say close the door, you're letting the cold in, they are actually, RIGHT.

You are letting in particles that are colder than the gasses inside, therefore, you are letting the cold (substance) in.

Things can be relatively cold, but there is no such thing as "cold" in reality. There's just varying amounts of heat everywhere.

>> No.6149357

>>6148287
No, because cold does not exist. It is not a thing. Cold is simply the concept of the absence of heat. Kind of like how darkness is not a thing, it's just the absence of light. Or how your vagina is not a thing, it's just the lack of a penis.

You just did, fagtard. And I'll do it again. Heat, unlike cold, is made up of something, and therefore is quantized and can be quantified.
Problem?

>>6148434
Except there is such a thing as cold in reality, you fucking moron. It's called absolute zero.

>> No.6149395

>>6149370
still isn't cold.
just a zero point that all heat will flow to

>> No.6149414

the answer is yes.


the only thing that does not radiate is something at identically zero degrees kelvin or a pure vacuum state.

they have finite energy and entropy, but they are both in a ground state (zero point energy state in the vacuum quantum field).

these states don't radiate energy.

Heat is not a thing dumbass.


heat is the name given to the transfer of thermal energy in a system.


heat is a dynamic concept. it only has a definition during a change of the system's internal degrees of freedom (where internal can be redefined to include the arbitrary system and its surroundings ad infinitum until we are discussing the whole universe)

yeah, but you can prove anything with facts
