Correct.
Any dark matter sufficiently dense to alter spacecraft orbits (and that bar
is pretty high to begin with) will do...what to planetary and lunar orbits?
The answer is an exercise for the reader. |

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[/quote:1d4e3c71de]

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.

M = mass of the body,

The drag equation is,

As you are aware Uranus is unique in the solar system. It's orbital
axis is tilted 97 degrees so, unlike all other planets one side
continuously faces the sun rather changing every 8.5 hours. With an
eighty four year orbital period the very slowly changing illuminated
side gathers nearly constant illumination for many years while the
dark side no heat source at all. As we know heat flows from hot to
cold and the rate at which it does depends on conduction, convection,
radiation. Of course losses to space is pure radiation but within
Uranus its based on conduction and convection. This lack of uniform
heat/loss input probably severely affects the possibility of
convection currents resulting in the total lack of banding &
atmospheric disturbances. We should expect a severely asymmetrical
heat loss with most occurring from the back side of the planet. The
thermal profile is regulated by the composition and potential
convection currents in the planet. Conduction is much poorer than
convection and the core to surface thermal gradient and net flow is
regulated by the ratio of these. Since the surface heating is slowly
changing with the orientation of the planet so is the direction of
flow. Its periodic and slowly rotating within the planet as it
orbits. Bottom line is, I think we need to know a lot more about it
internal structure to answer well but I think this summarizes the
complexity of the problem.

I wonder how he determined the aerodynamic drag coefficient for dark

Tom Davidson
Richmond, VA
[/quote]
The "aerodynamic drag coefficient" for Pioneer
passing through dark matter is 59.67 and Reynold's number .431
resulting in observed deceleration
with negligible affect on large bodies such as earth.
http://arxiv.org/abs/physics/9905007 page 19
56 Mev quantifies the Adler heat.
The 56 Mev should be ubiquitously observed
as all celestial objects pass through dark matter.
Will FERMI confirm EGRET by observing such??
