Find someone besides you saying Stefan-Boltzman describes a one-way energy flow.
You keep just saying it, but as I know you've heard before, just saying it don't make it so.
Who needs to? The law itself says so....this equation describes a one way energy flow from a radiator to its cooler surroundings......this is what the equation would look like if it described a two way net flow between radiator and surroundings.......unfortunately for your argument, it isn't written like that...it is written like this.....one way. If the law itself says one way...how much more convincing do you need? Or is it true that you can;t look at the equation and simply see that it describes a one way energy transfer?
this equation describes a one way energy flow from a radiator to its cooler surroundings.
That describes a net flow. Nowhere does it say it is a one way flow. Fail!
