Enshrined by the laws of Austrian physicists Josef Stefan and Ludwig Boltzmann in the late 19th Century, scientists have long understood the general principles of heat-energy transfer between the sun and planet Earth.

But at much closer separations, where photons can effectively “tunnel” between two bodies, the maximum rate and size at which two objects – one hot, one cold – can transfer heat has remained unknown.
