I think you transposed the terms distance and speed...

No I didn't.


but other than that
it is a fair analogy and there is nothing peculiar about it

If it is a fair analogy, then the peculiarity is that light can be
beamed.

What planet did you study on to find so many things peculiar on
this one? Earthlings do it this way.

More primitive Earthlings manage quite well with a shadow or a pin
hole.
Perhaps the development of phased-array sonar is just around the
corner.
How could we have missed it? :-)

Hmmm... I hadn't tho't of that. I suppose limiting the possible paths is
just as valid as redirecting the possible paths. Just so you accept a
broad definition of *beaming*.

All we really know is that light moves at c wrt its source, where c is a

One way light speed wrt any other than its source can have any value,
depending on relative source observer movement.

How do you explain De Sitter's astronomical demonstration that
the speed of light relative to an observer cannot depend on the speed
of its source, relative to that observer?

DeSitter was an amateur without much of a clue. He was wrong.

Sometimes I feel like a complete failure.
The most useful thing I have ever done is prove Einstein wrong.

You want me to run your .exe program on my poor little computer??
Sorry, not until I know you a LOT better! :-)

Until then, why don't you just EXPLAIN to me in plain English
why you think that De Sitter was wrong?

In the 19th century Sherlock Holmes (Conan Doyle) said when you
eliminate the impossible, whatever remains, no matter how improbable,
is the truth.
Your all permeating gas is impossible.
Certainly we can revisit the ether concept, but it is still as
impossible now as it was when it was concieved.
Continuing to pursue impossible ideas is futile.

Thanks for the heads up. I would never have guessed
these guys were making this stuff up:

Approximately 99% of the interstellar medium is
composed of interstellar gas, and of its mass, about 75%
is in the form of hydrogen (either molecular or atomic),
with the remaining 25% as helium. The interstellar gas
consists partly of neutral atoms and molecules, as well
as charged particles, such as ions and electrons. This gas is
extremely dilute, with an average density of about 1 atom
per cubic centimeter.

Calculate the bulk compressivity modulus for a hydrogen-helium gas of
density 1 atom/cc.
Calculate the speed of propagation of a signal in such a dilute medium.
Compare that to c.

The propagation of light is electrical... not mechanical.
