I read an article a day or so ago titled Hydrostatic Lapse, which makes the case for a phenomenon that I thought was well and truly confirmed; that gravity is responsible for the cooling of air with altitude. However I discover in the sequel article The Gemini Cycle that this phenomenon is supposedly in conflict with the second law of thermodynamics. After a bit of research, I find that Vanquish Opprobrium (author of those articles) isn't the only one who thinks the two are incompatible. Robert G brown from Duke University also makes the case for incompatibility in Refutation of Stable Thermal Equilibrium Lapse rate. Although both agree that they are incompatible and assert that in very similar ways. Robert G Brown comes to the conclusion that a hydrostatic gas is isothermal in nature, where as Vanquish Opprobrium comes to the conclusion that the second law is likely false. Vanquish Opprobrium is probably a crackpot, hence the nom de guerre. Yet hydrostatic lapse seems so intuitive. If an atmosphere's gas particles didn't slow at higher elevations, they would escape earth's gravity field and we would be left with no atmosphere. Surely they are both wrong?
