Let's check for gravitational screening, simple...

Larry,

I've checked about the Walker-Dual experiment (thanks, Tom), and it looks like my scheme has virtually nothing in common w/theirs. They try to measure the speed of first-order field variations in longitudinal direction from an oscillating dipole (gravitational/electric). This has nothing to do with gravitons/shielding.
Furthermore, my scheme provides for a huge amplification factor to the shielding effect detection sensitivity.
Anyway, thanks for your comments.

I've not been able to find anything recently either. But here is a quick summary:

The purpose of the experiment is to measure the speed of gravitational interactions.

Two rods with the same resonant frequency are suspended near each other. One is forced to vibrate, the other is monitored for sympathetic vibrations. All sources of energy transfer are blocked so that the only possible connection is gravitational.

Gravitational coupling (whatever the actual cause of gravity) is supposed to be strong enough to make the second rod vibrate out to several meters. Resonance amplifies this vibration to detectable levels.

The relative phase of the vibrations in the two rods is proportional to their separation and the speed at which gravitational influences travel.

By measuring phase delta at several different distances the speed of gravity can be determined.

If one set up a parallel channel (not part of the original experiment AFAIK) using a light source mounted on the first rod and driven by the same signal driving the first rod, and a photo detector on the second rod, the expected outcome is that the phase of the received signal would be retarded more and more as the transmitter is moved away from the receiver (since light travels at about 30 cm/nSec). With modern equipment this amount of phase shift should be easy to measure.

The Meta Model predicts that the phase difference for the gravity channel is so small (speed of propagation so large) we will measure zero until we get much better equipment.

I understand that funding was lost before the formal experiment could be preformed. But informal testing during development is supposed to have always produced a phase shift of zero. I don't know if this can be confirmed.

IMO the aparatus should always include a parallel light channel as a control. This would make it easier to spot technique errors and equipment problems. And make it harder to ignore or discount the results.

The matter of fact is that some inexplicable coupling between two identical x-talls exists. I've seen it between two very old 150 kHz quartz x-talls measured about 20mm x7mm x0.7mm. When the "transmitter" x-tall was replaced by a piezoceramic equivalent (amplitude roughly the same as controlled by reflected laser beam), the coupling was much weaker ,just as expected from parasitic acoustical coupling. I did all that in 1986...<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>
I was wondering about that from your earlier reference. My first reaction is that there needs to be some very critical alignment between the crystals to have any hope of detecting something, if gravitational shielding is responsible. But on second thought all that is reall necessary is that the second crystal have the propper resonant frequency, good Q and be located on the axis of the first crystal. The goal is not to move the crystal but to make it vibrate. Some particular alignment would work best, but many other alignments might work well enough.

The known existance of acoustic energy transfer in your experiment makes it unlikely that anyone will accept the reaults as anything else.

LB

Right, that's exactly why I propose that somebody with better resources than I tries my scheme out. Some theoretical support wouldn't hurt as well.
You see, I'm not a physicist anymore. I stopped being an experimenter 15 years ago to become a businessman.

I'm always interested in good investments in science, but, I have no idea what this is all about. Are you attempting to measure something having to do with gravity or make an antigravity device or what??

That Walker-Dual experiment got me thinking in an engineering way.
There is a lot of industrial quality equipment deployed that could be used in the electrical variation of their scheme. That equipment is the planar Phased Array antennae. An ideal case would be an array of phased dipole antennae aligned perpendicular to the plane of the array. That way the normal RF radiation would spread along the array plane, while the longitudinal field would be exacly the first-order variating field with zero conventional EM-wave content. Thus the probably ftl communication can be done on existing equipment.
The main downside of the first-order field signalling is that, for the far-field case, the field attenuates as 1/r^2 rather than 1/r of the conventional EM waves. But the advantage is that first-order field cannot be reflected, so signalling through the Earth might be possible.
And why wouldn't they try it out already, I wonder!?

[tvf] Thanks, Larry. That explanation I can understand. Can the matter density in the planes of the atoms really be 10^13 times greater than in other directions?

AgoraBasta (MarketStop?) points out in another reply that this number is the quality factor of the crystal he has used. But, if the shadowing effect is zero between the planes of atoms in a crystal and non-zero along those planes, it seems possible that the matter density ratio could in fact be very large.
