Meta model and use of Logic

I'm afraid it's no joke anymore.

Speed of gravity can be easily measured in a desktop experiment - nobody cares.
Magnetic monopoles experimentally detected 13 years ago - nobody cares.
Low-energy nuclear transmutations happen - experiments are ignored.

These three examples are my favourites, but the list could be continued endlessly...

I am interested in the three experiments but I never heard of any of them until just now. Well I know low energy transmutations can be done but not anything about experiments being done.

With all my sympathy and respect, Agorabasta, I am sitting here on my desk and I want to measure the speed of gravity. How do I do that?

I am not really disputing that you may know of a way of doing it but telling us how would help us to agree with you. Except if that's a classified experiment.

I have proposed a simple experiment to measure probable gravitational shielding and speed of gravity in another thread at this BB [url] www.metaresearch.org/msgboard/topic.asp?TOPIC_ID=38 [/url]. Here I reformulate the idea once again:

The idea is quite straightforward. Use the same Walker-Dual scheme as described here - www.arxiv.org/PS_cache/gr-qc/pdf/9706/9706082.pdf but with some technological improvements; instead of using two dipoles of macroscopic masses oscillating at a rather low frequency, better use two big quartz crystals of identical resonance frequencies and of very high Q-factor. Arrange the x-tals along the axis of longitudinal resonance mode. Put the "transmitter" crystal into active oscillation, then use the other one as a receiver. The Q-factor of 10^11 must be quite realistic for a crystal of a size of about one inch at longitudinal resonance mode, so sensitivity for a non-modulated signal must be very high, thus phase velocity measurements are no problem at all. (In fact, the bigger old-time x-tals really do show very strong parasitic coupling of non-EM and non-acoustic nature.)
To get the group speed we'd need to use some sort of modulation. I'd propose a mechanical or electrical delta-pulse excitation of the transmitter superimposed upon native resonance oscillation, it should produce a phase spike in the receiver crystal output by exciting higher harmonics. The best case for phase-amplitude detector inertiality is about 1/8 of the period of the main resonance, that would be about 10ns inertiality at the detector side; the Q-factor won't be helpful in this case, so it could be better to directly record the burst of higher harmonics in the receiver. If gravity pulse propagates at the same group velocity as light does, then 10ns means 3m. So the sensitivity of the system needs to be sufficient till 1m distance at least for the measured delay to be of the same order as the systematic inertiality, which is quite realistic for big xtals.

Regarding monopoles and transmutations, try this link (earlier linked here as well) [url] arxiv.org/ftp/physics/papers/0101/0101089.pdf [/url], or a newer one in Russian [url] jre.cplire.ru/jre/mar00/4/text.html [/url].

Here is my basic understanding about crystals:

When they are squizzed they generate electric current and when current is passed through them they oscillate at a frequency that depends on several factors.

If we have two crystals along an axis and excite one, why the other one should be excited? Due to acoustic coupling? Due to mutual induction? And what this excitation will have to do with gravity at all? Gravity is there anyway. How it is affected by the coupling? And if it did, how do we separate the component due to gravity from our measurements?

I propose a variation of you experiment:

Since gravitational force depends directly on the product of the masses, find a way to suddenly split one crystal into two pieces and remove its contribution to the excitation. Then, there should be a decrease in the Gravitational force by a factor of 2 and that decrease should be trasmitted (supposedly by gravitons). Since the new frequency of the split crystal is know, we should be able to calibrate the device for the action of the force due to gravity. But we must be able to measure very small changes in frequency and I do not know if that's possible. I have no clue but you may have.

What do you think?

Another idea:

Use three crystals in a iscosceles triangle arrangement and suddenly seize one. This has to me modeled though. Three body problem. But you do not have to split (no destruction in the experiment)
