Many credited physicists have entertained the notion of a non radiative atmosphere being isothermal as a function of height. But is this a physical reality? Many physicists accept the macroscopic conclusions of kinetic theory, the gas laws. Statistical mechanics. Experimentally verifiable results from a set of provably reliable assumptions. So what is wrong with these assumptions and their inevitable conclusions; "Particles are small and spend most of their time between collisions. They have mass, and therefore feel gravity." The inclusion of the latter in the frame of the former requires that 'information' about gravity is invested in the very framework of collisional energy transfer. This is supported by data. So what, despite supporting data, is wrong with kinetic theory. Why is it not supported by the scientific community?
