I have to respond to this one. The idea that space is a "medium"
through which energy flows was dispelled over a hundred years ago by
the results of the Michelson Morley experiment. If space were a
medium for EM propagation it would constitute a frame of reference
for an absolute velocity measurement.
Although the relative vacuum of outer space is not empty due to
quantum effects, it does not constitute a "medium" or a conductor of energy.
