The gas of gravitating bodies traversed by light, described in Part I, is not the end of the story. Seven years later, Klaus Sonnleitner proved with high-precision Hamiltonian numerical simulation methods that the counter-intuitive behavior described by Zwicky indeed holds true [1]. Hence virtually all previous numerical simulations of many-particle Hamiltonian systems were misleading. The same result was independently found analytically in the United States by Ramis Movassagh the same year [2].
