WebMay 9, 2024 · In addition, radiant heat does not require a medium or intermediate material to transfer the heat. In fact, a vacuum is the optimal condition for transferring radiant heat since in a vacuum there is no gas in the way to scatter or absorb it. WebMay 31, 2024 · One can also realize why perfectly transparent objects do not radiate by considering thermodynamics: in vacuum they would radiate away heat and become colder, and would eventually become colder than the background radiation. At that point one could connect them to a heat engine and have a perpetual motion machine. Jun 1, 2024 at 11:11
