A Classical Gravitational Second Law Paradox

摘要: A member of a growing class unresolved second law paradoxes is reviewed [1,2]. In sealed blackbody cavity, spherical gravitator suspended in low density gas. Infalling gas suprathermally strikes the which spherically asymmetric between its hemispheres with respect to thermalization probability for principle, this system can be made perform steady‐state work solely at expense heat from bath, apparent violation law. Detailed three‐dimensional test particle simulations support prediction. Experiments corroborating central physical process paradox are discussed. This fully classical mechanical nature and would have been understood by 19th century physicists.
