I told you already: you're trying to argue with the wrong person. I'm going to answer this, and them I'm done. You've been hammering at this unsuccessfully for over 2 years now. To say that it has been an outrageous waste of my time even answering you is an understatement.
Again, Dr. Latour claimed that mainstream physics, which includes absorption of cold back-radiation, "would constitute creation of energy, a violation of the first law of thermodynamics.
No, he didn't. I swear, you are the King of mis-stating other peoples' arguments, so you cay try to shoot down straw-men instead.
What he actually argues is that Spencer's argument, not "mainstream physics", would result in creation of energy. His actual argument is that "mainstream physics" (which he has used almost daily in his career as an expert in heat transfer) shows that it can't be so, therefore Spencer's argument is false.
That's not the same, and your claim that it is just shows you either misunderstand, or you're lying. After 2 years of this shit, I strongly suspect it is the latter.
The key phrase is "however slightly" because that difference can be made arbitrarily small. Since the only objection you've raised is arbitrarily small, does that mean you now see...
Now I KNOW you're just spouting bullshit. Because you well know that even "arbitrarily small" is not zero. And any deviation from zero is enough to make the difference between T and T0 (or however you want to designate them) non-zero. A non-zero difference is all we need, no matter how "arbitrarily small" you try to make it. Remember that this is physical substance, not merely a mathematical abstraction.
you now see that Dr. Latour is wrong to claim that the heated plate will stay at 150F after the second plate is added, because he wrongly claims that absorbing cold back-radiation would violate the first law?
He doesn't wrongly claim that absorbing any "cold back radiation" would violate the first law. Again, you are merely mis-stating his actual argument. Now YOU are confusing absolute transfer with net transfer. That's your problem, not his. His argument has always been about NET transfer, and he does NOT claim that "any" re-absorption would violate the first law. You are again trying to claim that his argument is not about net transfer, when it fact it always has been. You are tilting at windmills again. Or still, take your pick. Why do you persist in this? Who are you trying to convince? You sure as hell aren't convincing me of anything. I mean, hell, YOU just tried to imply that an enclosing mass can be made of negligible mass, to the point that we don't even have to take it into account. Hahaha.
I mean that's so wrong on so many levels. For one thing (I already mentioned another), if the mass were negligible (as it would have to be, to make the difference in dimension negligible), then it would also absorb and re-emit negligble radiation, which makes the whole argument moot. And I have to wonder again why you don't see these glaringly obvious problems with your arguments. If you reduced the mass (and thereby dimensions) to almost zero, you reduce the absorption and re-radiation to almost zero. You can't have it both ways. Unless you want to hypothesize about some mystery substance that is not known to exist in reality.
So Dr. Latour was wrong to claim that mainstream physics predicts the heated plate warms infinitely.
He doesn't claim that. Repeat: you are mis-stating his argument. He actually claims the reverse: he USES "mainstream" physics to show that in reality it does not warm infinitely, and therefore Spencer's argument was wrong. I mean you're just absolutely trying to reverse the real argument here. But I really don't expect you to see that, because if we assume you're being honest (which I do not in fact assume), you don't even see the enormous gaping holes in your own argument which you made above. IN REALITY, the enclosing plate will be somewhat cooler. That's not even advanced physics, it's simple math. Repeat: why can a layman so easily poke holes in your "physics" arguments? I'm not a physicist, and haven't claimed to be one.
This is an important point. Greenhouse gases can insulate Earth's surface because they're warmer than the cosmic microwave background radiation.
You're wrong about that too. Thermal insulation does not work by blocking radiative cooling. It inhibits convection and conduction. There is no convection or conduction between Earth's system and "the cosmic background". Only radiation. You have conflated two wholly unrelated concepts, and called it an argument.
I am DONE with your nonsense. If you think you really can refute Latour, then go do it, and stop bothering me. I have nothing to do with it. But I don't mind saying I wouldn't mind a bit if the whole world saw your foolishness as clearly as I do. So go do it, if you think you can, and leave me be. I am done here. I will respond no more to this stream of BS.
But before I leave, I'm going to do you a favor here. You don't deserve it, but I'm going to anyway. Here's a hint, if you really want to examine the difference that convection and conduction make, then take a strong look at how LONG it takes the Moon's surface, with no atmosphere, to cool off once it rotates into shadow.
Argue about that all you like, but with yourself. I won't be waiting to hear it.
