Can the phenomenon of quantum tunneling be explained? Any theory that can account for it? Or is it just empirical? Would someone kindly answer my questions? o:)
I see, so we are actually talking about the temperature of a body in space. But are there any other mechanisms besides EM waves that can have the same effect? And can we assign a temp to dark matter? As I know dark matter doesn't emit any radiation.
As temperature is emergent and is only describing the speed of molecules in a substance, is it meaningful to speak of temperature in an empty space? If not, can we say that the microwave background radiation is "heating" up the universe? As most of the universe is empty space
