Nothing.

As before, detection is not sufficient to describe.

No detection is exactly the right term as that's what happens. When
the photon is detected then the wave function collapses into a
deterministic state (that is it acts like a particle). But if you
don't detect it or try and detect it before the second half silvered
mirror it acts like a wave and interferes with it's self. Put a
detector anywhere before that mirror and it won't because it reverts
to it's particle behavour.

What we have here is something that is easy to observe yet remains
beyond our current knowledge! We don't know why the wave function
collapses, only it does. But then this is not the only thing we know
how it works but don't know why it does this or behaves as it does.
For example gravity. We simply don't know what gravity actually is,
only how it behaves.

Well that is just false Stew, when the photon is not detected at the
live bomb, then we know that it is on the other path, even before it
is detected at the end.

No, we don't know that till it gets to the end. Until some detection
happens we don't know. Photons do travel the speed of light you know
(to state the bloody obvious).

And it is simply false to omit decision from
the explanation, because the explanation must be distinghuished from
scenario's where the photon could not enter the lower path. Tell me
how the photon behaves before the wave reaches the live bomb.

As a wave the photon takes both paths but as there is a detector there
then that collapses the wave into one of the possible states, be it at
the bomb or at the top detectors.

No decision needed as it's based upon chance.

Gravity is an anticipatory force, as Dubois showed, a very satisfying
explanation it seems to me.

No idea where this came from - I'll ignore it for now as it's nothing
to do with this discussion.
