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."

Perhaps you should read up a little on fluid dynamics. Any movement in
a fluid causes "shock waves" or disturbances caused by energy transfer
to the fluid. The so called speed of sound is when the cause of the
disturbance moves at the same speed as the propagation of the energy
transfer.

Are you saying space is a fluid?
