One way of imagining a way in which this could happen is if a block of
material is energised to a high energy state. Photons are continually
fired
into the material and are absorbed one by one with atoms within the
structure absorbing each new photon. At some point, the material
becomes
completely saturated and cannot absorb any more photons. When the next
photon hits and is absorbed, a shockwave propogates through the
material and
a photon is emitted from the opposite side travelling at the same speed
and
in the same direction as the original absorbed photon. Stability is
restored
and energy is conserved.

But, it is the shockwave that has propogated faster than the speed of
light
and it is not the original photon that entered the material that is
emitted.
The emitted photon will contain exactly the same properties as the
absorbed
photon and the two would be indistinguishable. So the photon appears to
have
been transmitted through the material at faster than light speed, but
no
laws have been broken.

A Newtons cradle can help with visualising how this can happen.

Mike,

You had me fooled. It appeared that you might actually know something.
But that response bent the needle on my bull**** meter.

Actually that response is very credable, It is analogous to what happens
when electrons travel in a wire. Put an electron in one end of a wire and
one pops out the other end almost instantaneously even though the actual
speed of electrons flowing ththrough the wire is very, very slow.

Jimmie,

No particular argument about electrons in a wire. However, the stuff
proposed by Mike bears little resemblance to the wire.

How about:

Atoms absorbing photons one by one, i.e. one per atom in a solid? Doesn't
match anything I have ever learned.

Material becomes saturated with photons? What is this, a bag of marbles?

Shockwave propagates faster than speed of light? (Yes, I am familiar with
Cerenkov radiation. Not interesting in this context.)

Emitted photons contains exactly the same properties as the absorbed
photon? How do they get absorbed yet remember everything? How do they know
when and where they should pop out the other side?

Every part of that proposed explanation was nonsense.

Yes, nonsense as we now understand it, most great breakthroughs in physics
have at one time or other appeared to be nonsense, The Earth is a sphere,
the sun is 93,000,000 miles away, pepole can fly were all considered
nonsense at time. It is sometime difficult to keep a grasp on reality while
still being able to ponder the things that make for truly great break
throughs in science.
