Whats the matter ian, you have the same reading and comprehension problem as toddster. I have never...i repeat NEVER said that it is not possible for radiation to move from cool to warm. Like you, toddster is making up an argument for me and then arguing against that fantasy rather than my actual statements. I have lost count of the number of times I have pointed out to toddster that what I said is that radiation does not move SPONTANEOUSLY from cool to warm...and that you can move as much radiation from cool to warm as you like so long as you are prepared to apply work to get it done
So now you are building a new additional set of epicycles to prop up your ridiculous version of thermodynamics. The 'work' done it!
Hahahaha. Soon you will pick out a definition of work that you can misinterpret in a self serving way.
Why do you 'work' so hard to deny that every object radiates according to its temperature all the time?
By the way, the answer to why Sun's surface radiation reaches us is simple. It is the same reason that some of the Earth's surface radiation escapes directly to space. Most of the Sun's radiation is simply transmitted. The ions that make up the Corona are not blackbodies. And they are very rarified. The vast, vast majority of the Sun's radiation simply does not interact.
So now you are building a new additional set of epicycles to prop up your ridiculous version of thermodynamics.
All his work to prove that back radiation is impossible. What a joke.
Yup. Physicists don't typically call it back radiation, they just call it radiation. Every object radiates, the net radiation describes the heat flow. It's all quite simple really, unless you believe only the net flow is actually created, meaning the warmer object produces less radiation than its temperature suggests, and the cooler object doesn't radiate at all.
Perhaps SSDD'S new found toy, 'work', will explain it all.
