Here you go - matter disrupts the patterns of vibrations in the surrounding medium by sending out its own vibrations, these foreign vibrations are assimilated by the medium and this process requires supplying a momentum flow onto the matter to cancel out the momentum of those foreign vibrations.

Are you saying the vibrations becomes the gravitasional 'information' traveling between MI's? These pieces of information tells the MI to attract each other? This sounds to me very much similar to the more classical ideas of what gravity is where particles (or waves) 'sent' from one object can tell another to come closer to the first. Perhaps it is true but personally I prefer a more 'plain' explanation like the shadowing effect as explained in 'Dark matter...' and 'pushing gravity'.

Nope. It's the reaction of the medium trying to kill the "vibrations" of the matter by the means of sending more of the medium's proper "vibrations". That's exactly equivalent to the particle gravity model but without introducing gravitons as such, equating gravitons to the "phonons" of vacuum.

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

As a "meat and potatoes" engineer, I would like to point out a distinction between gravitons and wind in our atmosphere. A sailing vessel works because the dimensions of the sails are far larger than the mean free path of an air molecule. Presumably, for gravitons, the exact opposite is true. The mean free path of the graviton is vastly larger than the vessel or even the length of the voyage (eg a solar system trip). So, putting gravitons to use for propulsion will differ greatly from the mechanism of a sailing ship.

I hate to disagree with a "meat and potatoes engineer". But I submit that if all air molecules moved in parallel and never collided so they had no mean free path, the sailboat (which depends on the wind speed to get its momentum) would work just as well. The air molecule speed that causes molecules to bang into one another simply creates sea level atmospheric pressure, but no net force. Only a collective motion of molecules can produce a force that can do work.

By analogy, the graviton wind continually blowing toward the Earth's surface could be used in the same way to do work. What stops us is that any sail we would build today would be like using a fish net as a sail on a sailboat. Both are too porous to catch the wind. -|Tom|-

I hate to disagree with a "meat and potatoes engineer". But...

I stand corrected. I have my steam evacuator blinders on. If a sail that perfectly reflected gravitons were placed within a uniform flux of gravitons, it appears that it would have no net motion since any forward path of a graviton would be cancelled a graviton following the path in reverse.

If there is a gravitational "wind", that is, a net difference in the local flux, then the perfect sail would go in the direction of the "wind". Any space rock is doing this as it approaches Earth, but in a very inefficient, porous manner. If you raise the density high enough to utilize the wind, you have raised the mass of the sail. It sounds like a losing proposition: increased resistance to motion cancels out the increased capture of momentum. Or am I hare-brained?
