'Elastivity' of graviton collisions

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>[Rudolf]: what the meta model takes as one of it's assumptions for gravitons are that their collision with a MI (matter ingredient) are 100% elastic.<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

This step was later shown to be incorrect by Hayes and Slabinski. See "Notes on gravitation in the Meta Model", Meta Research Bulletin, v. 7, pp.33-43 (1998). The correct mix of absorption and scattering for gravitons was shown in the chapter "Gravity" published in <i>Pushing Gravity: New Perspectives on Le Sage's Theory of Gravitation</i>, M. Edwards, ed., Apeiron Press, Montreal, 93-122 (2002). See also V. Slabinski's chapter in the same book, “Force, heat and drag in a graviton model”, 123-128.

The bottom line is that energy, momentum, and entropy are preserved when averaged over all particles and waves, so the infinite universe is neither heating up nor running down. -|Tom|-

If the energy is 'preserved' (as I also believe it is) is there a step or process to recreate gravitons again? In other words if graviton collisions and absorption 'take' energy from gravitons and convert or transform it into heat or other forms of energy would'nt there be a point that the universe 'run out of' gravitons unless there is some source of it again? Perhaps the answer is already available in the new book 'Pushing gravity' which I have ordered but not received yet (through amazon sorry .
Another subject I have been facinated by is wherever it would be possible to manipulate gravitons somehow in a practical manner so we can build space traveling vehicles etc.

Yes, on the quantum level it is radioactivity and spontaneous photon emission. On the macroscopic scale it is planetary and stellar explosions. Eventually, everything that collects into matter dissolves back into constituents. But new assenblages are always forming, so the universe is not changing overall, just in its details.

In principle, that should be easy. We just need to find a way to engineer matter so dense that gravitons cannot get through. -|Tom|-

I suspect producing anything this dense would be almost impossible - at least for our current level of technology. Are there any other means that gravitons can be manipulated even if it is just on a 'small' scale?
Could any of the other forms of energy transformations have any affect of the smaller gravitons like electromagnetic, weak or strong nuclear forces? Or perhaps the opposite, inducing graviton type of 'pushing' using some or a combination of the other forces?
I don't know enough to speculate myself but perhaps if no one has thought of it this way it could be examined?

I'd like to point out once again that the gravitons don't really need to be real particles; instead, they may be just the "phonons" of the vacuum (or ZPF). In this sense they may be equal to the instantaneous "virtual longitudinal photons", as the carriers of the Coulomb electric field are often dubbed.
This approach raises the possibility of acoustical or thermodynamic modelling of gravity. The most interesting would be the thermodynamic model with solid state objects submerged in liquid. It's very easy to demonstrate that the object/medium border should attract a momentum flow carried by the native phonons of the medium toward the border, which momentum flow drags the other objects submerged in the same liquid. One of the features of the model is that the drag is dependent on the proper volume of submerged objects and on the internal properties of those objects affecting their native phonon spectra.
Here's a simple qualitative explanation of the thermodynamic phonon "gravity":
The "elasticity" of the phonons interaction with the medium depends strongly on the properties of the phonons, that being near-perfectly elastic for the native modes' phonons and strongly inelastic for the "foreign" phonons. Thus the foreign phonons are absorbed near the border. The integral energy flow being uniformly zero in case of thermodynamic equilibrium, the momentum flow from the foreign phonons inside a submerged object cancels itself out, while the momentum flow from the foreign phonons in the surrounding medium is generally non-zero through any surface not including that object entirely. To compensate that momentum flow and to contain it in the area of foreign phonons absorption, a momentum flow from the surrounding medium must be supplied by the native phonons. Thus a gravity analogue is produced.

Interesting idea but I must confess that you lost me a bit on the explanation of it. Would there be a simpler way to explain this idea of gravity that may be thought of acting like a liquid or something? Preferably in a more laymans language if possible.
