Sounds like he's talking about the Aether Theory without actually
mentioning the Aether here.

No, its got nothing whatsoever to do with that.

Doesn't the Aether Theory say that things moving in space in a certain
direction shall feel a "wind" as they move? That sounds like what he's
talking about.

The "wind" here is Galactic gravity which is responsible for flyby
anomalies, especially pronounced at perihelion and aphelion, where the
planet
is aligned with the Sun and Galactic Center. At aphelion galactic
gravity
is additive and subtractive at perihelion. John Curtis

Technology Review: Blogs: arXiv blog: The Clue That Could Explain The
Fly-By Anomalies
"Last year, we looked at an idea from Stephen Adler at Princeton
University, that suggested the change in velocity could caused by
collisions between the spacecraft and particles of dark matter. Adler
even calculated the kind of distribution of dark matter particles that
would explain the observed changes in velocity--a kind of halo of them
around Earth. "

Funny that the earth is surrounded by enough of these to noticeably slow
a spaceship, but none has even been observed on earth. I wonder if the
paper has an explanation of this curious fact ...

There's a lot that's funny about Dark Matter.

Ultimate disposition of dark matter may require abandonment of
heliocentric system in favor of a galactic frame. Copernicus and
Kepler
will join Ptolemy, Newton will require modification. John Curtis


Ultimate disposition of dork matter theory may require
abandonment of a galactic frame. Curtis and Khan will
join the black hole brigade, Newton will require no
modification. Androcles.
