The hypothesized "push" results from a differential pressure, due to partial
absorption of background radiation by matter.

In effect, we are in the earth's "shadow", and are hence pushed in one
direction, toward the earth, to a greater extent than the push away from the
earth.

There are more than a few theories that predict that gravity can be shielded.
In fact some theories, modern and non-modern, suggest gravity itself results
from a differential shielding effect, with the apparent force of gravity
caused by a push or pressure due to shielding by bodies of matter from the
background radiation of free space. Some of these theories do a fairly
thorough job of providing a detailed model of how things work -- including
just about everything.  Some of the better written of these appear to be no
more or less experimentally provable than General Relativity.

One of their main drawbacks might be that they weren't created by Einstein.
Still, some of them are written by notable and respected physicists such as
Sakharov and Puthoff -- and there are a raft of others with similar proposals
and ideas.

There is also experimental evidence that gravity can be shielded.

There are of course, the inventions of Henry Wallace, a scientist at General
Electric, who received patents in the early 1970's for devices which
demonstrate the capability of shielding and control of a gravitational field.

Although, Wallace's work is possibly of earth shaking importance, any further
efforts or independent verification and tests of his discoveries are
mysteriously absent from the scientific record.

Some folks, myself surely included, believe that our military black project
community has clamped a lid on the whole thing. But let's leave the Wallace
story for now, and look at a more recent experimental finding. If anyone would
like more information about the Wallace inventions, please send an email
request to: robert@wwa.com

In a very recent vein. Here's some information about a startling experiment
that was reported in early 1995, which found that a gravitational shielding
effect can be attained by spinning a mass of superconductor material. There is
also a separate article which provides a theoretical analysis of how this
might be possible.

Is anyone familiar with the experiments of Podkletnov et al on weak
gravitational shielding from a Meissner levitating, rotating disk of high-Tc
superconducting material?

The paper is: E. Podkletnov and R. Nieminen, Physica C 203 (1992) 441.
E.  Podkletnov and A. D. Levit have another paper now, a Tampere University of
Technology report, January 1995 (Finland), the experiment having been repeated
(I assume no one believed it the first time?).

In the 1st experiment a 5 gram sample of silicon dioxide was found to lose
around 0.05 % of its weight when placed at a distance of 15 mm from the SC
disk.

The SC disk had diameter 145 mm and thickness 6 mm.

Under rotation of the disk the effect increased up to 0.3 %.

In the 2nd experiment samples of different composition and weight (10-50 g)
were placed at distances of 25 mm to 1.5 m from the disk.

The mass loss went as high as around 2 %.

I found out about this through a theoretical preprint by Giovanni Modanese, a
Von Humboldt Fellow from the Max Plank institute. The preprint no. is MPI-
PhT/95-44, May 1995.

A colleague got it from hep-th@babbage.sissa.it, paper 9505094.

Modanese thinks that it is something to do with the Bose Condensate from the
SC interacting with the gravitational field. He uses some non-perturbative
quantum theory on the Regge lattice to attempt to understand the effect.

Must be a little bit like explaining cold fusion with the standard tools -
couldn't be done. We all know what happened to cold fusion but at the time a
professor from my department said in a public lecture that the product of the
believability and the potential importance if true was of order 1.

Title: Theoretical analysis of a reported weak gravitational shielding
       effect
Author: G. Modanese (Max-Planck-Institut, Munich)
Report-no: MPI-PhT/95-44   May 1995

   Under special conditions (Meissner-effect levitation and rapid
   rotation) a disk of high-Tc superconducting material has recently
   been found to produce a weak shielding of the gravitational field.

   We show that this phenomenon has no explanation in the standard
   gravity theories, except possibly in the non-perturbative quantum
   theory on the Regge lattice. More data, and independent repetitions
   of the experiment are however necessary.
