    This is extremely strange. Shouldn't this be impossible by the second law of thermodynamics?

    Receiving more energy when a resistor in thermal equilibrium is connected to an antenna seemingly implies that energy gets transferred from an antenna with a resistor to a an antenna without a resistor, even at thermal equilibrium.

    Maybe we'll later find it's an experimental subtlety, like the faster than light neutrinos.

      Now consider the alignments of red blood cells.
