Default Photons?

I guess he is picturing the quanta as a pulse of a wave which it
*isn't*.


Consider a quiet band, and you receive a single dit, the letter E in Morse
Code.

Before there would have been no signal and neither after the dit.

So, if your RF photons do not have a beginning and an end, as they must do
as pulsed phenomenon, how come there is only signal during the duration of
the dit?





Because the only time you hear the dit is when the radio wave is passing
your antenna. The radio wave continues on; someone one light year away
with a sufficiently sensitive receiver would hear the dit one year after
you.

But this has nothing to do with quantum physics.
