He did, though perhaps he assumed too much of you, it
is coherent because each detection is of a _single_
photon and any photon is of course coherent with itself.

So every single photon frm a distant star is stretched to over 600
metres
wide
by the time it reaches Earth?

That is for you to decide, you have to explain how
an individual photon's behaviour can depend on the
paths through both telescopes, Paul and I are only
telling you what the observed result is. It is just
a larger example of Young's Slits so you shouldn't
be too surprised.

....a much larger version.

VLBI is larger still but it still works.

A can't imagine a gamma particle 600 metres wide.....can you?

The limitations of our imaginations do not limit
reality. See this article and note the sensitivity:

"'We can find all the stars that send us more than
one photon per second.' said Mackay."

Each photon lands at a point on the image that depends
on the whole surface of the telescope and at that rate
it can't possibly be some sort of aggregation effect.
Interference applies to every individual photon.

It would be quite dangerous...and we're being bombarded by them
continuously...

It would be if we were, but the ozone layer stops them.

Have you now fathomed that, or will you still state stupidities like:
"Just tell me how photons emitted from opposite sides of a star can
end
up
in phase over a 600m wavefront".

Interferometry requires coherent light.

Interferometry works with individual photons even
in this configuration:

...and my statistical theory explains why...

More lies Henry? You don't have a statistical theory,
only Ritz's macroscopic velocity equation and my
extension for speed equalisation. In fact, come to
think of it, you have never originated anything for
yourself.


You're becoming as amusing as Paul....

Just stating a fact, you have no equations. You can
prove me wrong easily by posting them but until then
you are a liar.
