The net power, P, changes.Ergo the fact that he found that P changes as the difference in temperature between T and Tc changes...not because T is absorbing energy from Tc...but because it radiates according to the difference between the two temperatures..
You are confused. No I would say the power changes because of changes in emission and absorption of the object. Your hypothesis requires a dimmer switch.
One further note. You are wrong. Stefan was not looking at power P. It may have been too difficult to measure at that time..

You can't derive net from that equation...

You would say whatever you needed to say in order to support your belief...even to the point of altering what a mathematical equation says...or claiming that it is possible to derive net from an equation that describes gross one way energy movement.
You are wrong. Stefan looked at cooling rate. The final radiant power form of the SB equation was developed later from his cooling rate data.One further note. You are wrong. Stefan was not looking at power P. It may have been too difficult to measure at that time..
Sorry guy....wrong again...why don't you trying to read just for the sake of the information you can gain rather than skimming for anything that you think you can interpret to support your beliefs...
The Stefan Boatsman law is precisely looking at power...the amount of energy being radiated by a warm object...Do you ever take a break from making shit up?
Stefan–Boltzmann law - Wikipedia
The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature. Specifically, the Stefan–Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time
Stefan-Boltzmann Law
The thermal energy radiated by a blackbody radiator per second per unit area is proportional to the fourth power of the absolute temperature and is given by
the definition of stefan-boltzmann law
- law stating that the total energy radiated from a blackbody is proportional to the fourthpower of its absolute temperature.

The equation exists because it was derived from a net. See the Dartmouth text for the derivation. That derivation occurs in any textbook with SB details.

If you want to disagree with science then you are dead wrong.Sorry...I will stick with S-B rather than your idiot dartmouth paper apparently trying to support a narrative...S-B most certainly was not derived from a net...The concept of net energy exchange was decades away when the S-B law was formulated.

No that is a lie. I have not made up anything. It's in the textbooks of science. You have constantly professed that you don't believe in the science.If you want to make up history..it is you who is wrong... All the evidence....and all the physical laws are on my side...you on the other hand are a moonbat...
Just when it looks like that you maxed out in terms of hippie-physics stupidity you come up with another gem.Ergo the fact that he found that P changes as the difference in temperature between T and Tc changes...not because T is absorbing energy from Tc...but because it radiates according to the difference between the two temperatures...
One further note. You are wrong. Stefan was not looking at power P. It may have been too difficult to measure at that time. Stefan was looking at the cooling rate of an object under a uniform surround temperature. The cooling rate depends on the objects heat capacity; he referred to the Dulong–Petit law that made his experiments possible. Of course a material with a higher heat capacity would cool more slowly and that had to be carefully factored in.
The more fundamental reasons behind the SB law, namely radiation exchange, came much later when EM theory came about.
Nope I was talking about how Stefan did his experiment. A more detailed explanation came later with his student Boltzman.Just when it looks like that you maxed out in terms of hippie-physics stupidity you come up with another gem.
"Stefan was not looking at power P. Stefan was looking at the cooling rate of an object"
Now you are saying Herr Boltzmann was as stupid as you and had no idea that energy per time is the definition of power. You must be consuming some pretty potent "chill-out" shit to be able to communicate with Herr Boltzmann`s spirit when he told you that. Get some more LSD for another seance session and ask him what the W is doing in his σ Stefan Boltzmann constant. Maybe it`s W for Wuwei instead of Watts

So tell us how he did his experiment, the one you say he was not looking at power. Not that I care about your hippie opinion for reasons other than exposing the stupefaction effect of granting the mentally inferior equal rights.Nope I was talking about how Stefan did his experiment.

BTW chill out.

Still waiting for you to show me where we need a "dimmer switch" to show that a cold object can`t heat a warmer one.One further note. You are wrong. Stefan was not looking at power P. It may have been too difficult to measure at that time..

Your own source, refuting your dimmer switch misinterpretation.
You can call it whatever you want, the radiating object cools down.I suggest that you brush up on the S-B Law....it has nothing to do with absorption beyond the fact that it initially speaks to a perfect black body which absorbs all energy across all bands.....The S-B law is about emission...and how a radiator behaves.
That is exactly right. Boltzmann derived the equation
P = e sigma A T⁴
directly from Plank's black body radiation law. Plank's law defined radiation over a full spectrum. His student, Boltzmann, simply integrated over the full spectrum to get the above equation including an exact value for sigma for radiation.
Stefan found in his experiments the cooling rate of an object was not just dependent on the object temperatures 4th power, but also on the surround temperatures 4th power. He heuristically discovered a subtracted form followed the data.
Ergo the fact that he found that P changes as the difference in temperature between T and Tc changes...not because T is absorbing energy from Tc...but because it radiates according to the difference between the two temperatures...
To understand the experimental values of the cooling rate of an object, the absorption of heat of the object due to the surround at temperature Tc had to be considered. The input power that slows the cooling rate has a factor called absorptivity
Sorry guy...the story that goes with your bogus equation is bogus as well...
By the way...there is no two way Planck equation either...both understood full well that energy moves in one direction...warm to cool.
but because it radiates according to the difference between the two temperatures...
Dimmer switch!!

You are confused. No I would say the power changes because of changes in emission and absorption of the object. Your hypothesis requires a dimmer switch.Set T to any temperature above 0K....now set Tc to any temperature less than T...P will have a value...Now set Tc to a different temperature...higher than the first number you set Tc too...P will be reduced...you call it a dimmer switch...I call it obeying the laws of physics...The fact is that P is reduced...meaning the object is radiating less energy because the temperature difference between T and Tc is less. The colder Tc gets, the more the object radiates...
Nope, and you’ll never prove it. The equation calls T the radiator, therefore the surrounding doesn’t radiate.
