Gravity Shield discovered?

[Darkblade]

Scientists have noticed anomolous behavior of the gravity wave detectors on board gravity probe B. the behavior has been there since it was launched and no explanation has been satisfactory. they thought it could only be explained by defects in the shape of the fused quartz silicone superconducting spheres that are the heart of the probes detectors even though they were thoroughly inspected and found to be perfectly spherical to the 40 atom thick scale. however the anomolous behavior is in accord with theories of how gravity interacts with superconducting sheets. so though it is a bit early if they have actually done this it means what? anti-gravity and gravity shielding?

The new idea comes from considering what happens to a superconducting sheet when a gravitational wave passes by. The Cooper pairs within the sheet are quantum objects governed by the uncertainty principle and so cannot have specific trajectory: they are entirely delocalised. On the other hand, the ions that make up the crystal structure of the superconductor are not delocalised and so can move along a geodesic trajectory when a gravitational wave passes.

This is the basis on which a gravitational wave can interact with a superconducting sheet. “Quantum delocalization causes the Cooper pairs of a superconductor to undergo non-geodesic motion relative to the geodesic motion of its ionic lattice,” says Chiao and buddies.

They speculate that this difference in motion causes the sheet to absorb energy from the gravitational wave and then re-radiate it as gravitational wave travelling in the opposite direction–in other words specular reflection.

This implies that two charged, levitated superconducing spheres in static mechanical equilibrium, such that their Coulombic repulsion balances their Newtonian attraction, should be an efficient transducer for converting EM waves into GR waves and vice versa. A Hertz-like experiment in which a transmitter and receiver of GR microwaves are constructed using two such transducers should therefore be practical to perform.“

Dude. I've been to college. Best three weeks of my life. But I have no clue what the hell any of that meant.

[Darkblade]

it sounds like they have developed a device that can redirect gravity waves or produce waves via electromagnetic energy. in short; a gravitic analog of radio electronics. transducers, transmitters, receivers, diodes, amplifiers and so forth but with gravity as the energy manipulated instead of EM.

Many of us have seen the effects of gravity waves without realizing it when we look up at the sky and see sheets of clouds that are rippled as if a pebble had been thrown into a pond. The ripples are the effects of gravity waves interacting with the water molecules in the clouds. At least that's my understanding of this subject.

Time seems to fly by during the summer months, but seems to go slowly during the winter months.

This is fundamentally flawed; the Heiseinberg Uncertainty Principle doens't say discrete quantized particles can't have set trajectories, it says it's impossible to measure both position and momentum precisely. You can know one or the other accurately.

the second cite which i must assume you refer to is a peer reviewed MIT paper. somehow i think that the people reviewing the paper would have caught any such fundamental error. therefore i must assume that you misunderstood something in the missing cite.

Bumping so I can read in the morning with a clearer head.

Thanks Darkblade for finding this.

You are not seeing gravity waves acting on water molecules... The apparent ripples in clouds are caused by the same thing as ripples on the surface of water. Air acts just like a fluid... it has waves and thermoclines and eddies just like water. But since air is invisible, you cannot see them except when thin layers of clouds lie on the ripples or swirl in the eddies that form between two different strata (different temperature and/or density) of air. And because the clouds are made up of condensed water vapor, when on layer is warmer than the other, some of the cloud re-vaporizes in the warmer layer thus thinning the cloud along that "wave" and making the ripples more apparent.

This article http://www.wired.com/wired/archive/6.03/antigravity_pr.html (http://www.wired.com/wired/archive/6.03/antigravity_pr.html)
is on a related topic regarding a scientist who claimed to have found a way to sheild gravity some time ago.

There is also peer reviewed research done that proves that graviational waves can be reflected by superconducting surfaces.

thanks for the supporting evidence. the question i guess is are gravity waves just ripples in space time only incidentally related to gravity itself or or they saying that gravity waves carry "charges" of gravity and that as a consequence these superconductors can modify gravity itself?

Seeing that gravity is actually curved space I was have to take the wait and see approach.

Seeing that gravity is actually curved space I was have to take the wait and see approach.that is one way to describe or model gravity. however gravity is also required to have it's own carrier particle in the standard model.

Off topic but, The magazine article said this stuff was nearly as light as air and and strong as steel.

yes. amazing stuff. and even more amazing stuff is on the way with the advent of meta-materials.
