IMPORTANT NEW THEORY. “Generalized second law of thermodynamics in black-hole physics, by Jacob Bekenstein. Black-hole physics mirrors thermodynamics in many respects. For example, Christodoulou has shown that the efficiencies of processes for extracting energy from a black hole are limited by their irreversibility; the most efficient processes are the “reversible” ones.”
