The final expression of that equation is what I have been saying all along...there is no expression there for calculating net...
That is not true at all. The SB equation you have been saying all along always had the expression,
.... (T⁴ – Tc⁴) where you specified the second term was always colder.
The textbook equation we are now referring to has the form
.... (T₁⁴ – T₂⁴) where T₁ and T₂ can be any temperatures.
.
The second term is always colder...it is a fundamental assumption of the SB law...been over this over and over with you...that fact invalidates any equation in which the second term may be warmer...the tedium...it hurts...
