Yes. So? Do you imagine light can't propagate through a
vacuum?

It can't propagate though "nothing", now what properties are you giving
your "vacuum?"

Apparently you do so believe. Join Warhol, and HAND.

I am not prepared to discuss the supernatural/magical properties you
ascribe to a vacuum or nothing

I ascribe no such properties to the vacuum; the properties
are those of EM radiation, which requires no medium for
propagation; in fact, any such medium, from air to glass,
slows the apparent velocity of such radiation. Only in a
vacuum is it equal to c. You seem to consistently miss this
point.

... this would be better dealt with in a
religious NG.
