SB says that if the object is not in a vacuum, or at absolute zero, then it radiates according to its area, its emissivity and the difference between its own temperature and the temperature of its surroundings...
Of course, because dimmer switch. Seeing into the future. Measuring temperatures of targets without said targets radiating. Because photons don't experience time.
Did I leave anything out?
Weird that all your epicycles have no back up, eh?
Stefan-Boltzman doesn't say anything about a dimmer switch...that is just your weird interpretation of the equation.
As best as I can tell, the equation says that P (the amount of radiation being emitted by the radiator) is equal to the emissivity of the object (e) times the SB constant times the area of the object (A) times the difference between the temperature of the radiator to the 4th power T^4 minus the temperature of the radiator's surroundings to the 4th power (T^4 - Tc^4).
If you see something about a dimmer switch there, or simultaneous two way energy flow, or the radiator radiating simply according to its own temperature, or any of the other gross misconceptions you have about what that equation says, then feel free to point out the expressions that cause you to believe that the equation says anything other than what I just stated.
