Gravity well / Anti-gravity well |
A few months ago there was a news article about one of the early US
space probes that is now nearing the edge of our solar system. The
probe was slowing down without explanation. Several possible reasons,
dark matter, unseen object, were discussed without a conclusion.
The article got me to thinking. What if it was anti-gravity? Imagine a
gravity well. It drops from the spacial plane to the source of the
gravity. What if surounding the gravity well there was a ring of
anti-gravity. The force would be spread over a much larger area thus a
very weak force. It would be the equal but opposite of gravity with one
exception. Being spread over a vast area it would be almost
unnoticable.
This could explain the extra slowing of the probe and it would be a
very elegant explanation of anti-gravity.

Why a ring? The solar system is a 3D structure.
A spherical shell of something producing antigravity would
have no net effect on the interior.

I was using the gravity well model. It would have to be spherical.
Gravity relates to the area around the source, earth, sun,,, Why
wouldn't anti-gravity relate to the same area, just farther away. The
force would be so widely spread it's effect would not be noticeable
unless you were there or measured the change in speed of an object
passing throught the area. Now if the probe continues to be monitored
and anti-gravity does exist out there I would expect the probe to begin
to accelerate once it passes the peak of the anti-gravity well.

"were" not "was." Subjunctive case. It isn't. There is no mechanism
in any theory for gravitational shielding or repulsion. BTW, moron,
Pioneer is anomalously slowing not speeding up vs. the sun.

Uncle Al I believe I said slowing down. If anti-gravity exists out
there the probe should start to accelerate once it passes the peak of
the anti-gravity well.
There is no mechanism in any theory for gravitational shielding or
repulsion, yet.

You should find that article and get your head screwed on straight man!
There is *likely* a Newtonian explanation for the Pioneer 10 Anomalous Acceleration
Read the real papers
http://www.google.com/search?q=pioneer+10+site%3AarXiv.org
Ref: http://scienceworld.wolfram.com/physics/Gravity.html
Ref: Hartle, "Gravity: An Introduction to Einstein's General Relativity", Addison
Wesley (2003)
"A few properties of the gravitational interaction that help explain when
gravity is important can already be seen from the gravitational force law
F_grav = G m_1 m_2 / r_12^2
o Gravity is a universal interaction in Newtonian theory between all mass, and,
since E = mc^2, in relativistic gravity between all forms of energy.
o Gravity is unscreened. There are no negative gravitational charges to cancel
positive ones, and therefore it is not possible to shield (screen) the gravitational
interaction. Gravity is always attractive.
o Gravity is a long-range interaction. The Newtonian force law ia a 1/r^2
interaction. There is no length scale that sets a range for gravitational
interactions as there is for the strong and weak interactions.
o Gravity is the weakest of the four fundamental interactions acting between
individual elementary particles at accessible energy scales. The ratio of
the gravitational attraction to the electromagnetic repulsion between two
protons separated by a distance r is
F_grav G m_p^2 / r^2 G m_p^2
-------- = -------------------- = ------------- ~ 10^-36
F_elec e^2 / (4 pi e_0 r^2) (e^2/4pi e_0)
where m_p is the mass of the proton and e is its charge.
These four facts explain a great deal about the role gravity plays in physical
phenomena. They explain, for example, why, although it is the weakest force,
gravity governs the organization of the universe on the largest distance
scales of astrophysics and cosmology. These distance scales are far beyond
the subatomic ranges of the strong and the weak interactions. Electromagnetic
interactions COULD be long range were there any large-scale objects with net
electric charge. But the universe is electrically neutral, and electromagnetic
forces are so much stronger than gravitational forces that any large-scale net
charge is quickly neutralized. Gravity is left to govern the structure of the
universe on the largest scales.

Actually gravity may not be the weakest force, it may be the stongest
force, just not in this dimension, at least according to string theory.

M-theory makes no testable predictions. Until it does it is mere
mathematics at best and more likely meaningless philosophy. Listen
up, git, the entire mass of the Earth is trumped by a single excess
electron trapped in a bit of dielectric fluff. "Leaking gravitation"
wants for its books not being balanced.
