Does a light wave from Alpha Centauri that never encounters
anything except free space transport energy? It certainly
depends upon your definition of "transport". It has an
E-field, a B-field, and a Poynting vector but is it
"transporting" energy if it never encounters a load to
which to transfer energy?
