How about: A photon (particle) traveling at the speed
of light causes shock waves in the aether which, when
passed through double slits, causes interference?

Impossible for empty space - but we now know that space
is not empty. :-) Quoting "Alpha and Omega", by Seife,
"Empty space is an incredibly complex substance, and
scientists are just beginning to understand its properties."

Hello Cecil,

I don't believe you can compare the two phenomena.

The photons are created because of an accelerating charge (so the
photon is the wave itself, not the source that created the wave).

However, as far as I know, there is an (almost) equivalent for the
airplane/air shockwave. When you shoot a charged particle (v close to
c0) into a material with rel. eps 1 the particle will not abruptly
slow down when entering the material with high rel.eps. So it can
have a speed that is above the propagation speed of EM waves in that
material. In that case an EM shock wave occurs. Look for Cherenkov
shockwave.
