OR, Would a mass with no motion have gravity(i know zero motion is impossible)--since 'GRAVITY" is a symptom of mass in motion, the faster you go, the more you mass, and thus the force is stronger. i propose mass in motion simply warps spacetime( aka the gravity well) and thats why no one can detect a gravitron. am i stupid?
i am not a physics wiz- just a layman and amateur astronomer- Ideas?

You and Ernst Mach.
General Relativity explains gravity pretty well as a curvature of spacetime due to the presence of mass--whether or not that mass is in motion, that is, whether or not there is any way (like a background of stars) to tell whether the mass you're interested in is "moving."

The difficulty with detecting a single graviton is that gravity waves--even the ones made of zillions of gravitons--are very weak. Gravity waves have been inferred from the spin-down rates of binary systems, and the calculations are in very good agreement with the predictions of General Relativity. But a single graviton? That would require an extraordinarily long interferometer.

Actually, I think you are confusing "matter" with "mass". Mass is a property of matter. Gravity is a property of matter. All matter emits gravitons as a way of communicating its gravitational force. However, matter acquires "mass" by interacting with what's known as the Higg's Field, which permeates throughout space. The greater the amount of matter, the more "massive" it becomes (because the interaction with the Higgs Field becomes more intense). You can think of the Higgs Field as being like trying to move through molasses. If you are massless (like a photon), then you do not interact with the Higg's Field, and you can travel through space at the highest speed possible (the speed of light). If you have mass, then the more matter you have, the more difficult it will be for you to move through space. It would require more energy to move a more massive object than a lesser massive object (this is called inertia).

So now you know what mass is, and what gravity is, does your idea still make sense? Matter in motion could be a consequence of the gravitational force, but matter in motion does not generate gravity. It is the matter itself that is the source of gravity, i.e. matter on its own can warp spacetime.

BTW, the reason that the faster you go, the more massive you become is because of Special Relativity. This happens only when you are traveling close to the speed of light. The energy you put into moving faster is transformed into mass, thus you can never achieve speed equal or greater than the speed of light. Again, gravity has nothing to do with this. Also, at speeds much less than the speed of light, the faster you go has NO effect whatsoever on the mass.

Interesting. I suspect because gravity has been shown to be in direct proportion to the total quantity of mass with no discernable difference between like masses when different volocitites are involved, the idea that gravity is a symptom of mass in motion becomes pretty suspect.

Brownian action is a perpetual random action brought about with the aid of thermal fluctuations in the ambience. it relatively is the reason you are able to ultimately scent a fragrance at one end of the room whilst it is sprayed in the choice corner as an occasion. little bit of a lame occasion notwithstanding it relatively is all i will think of of off the spectacular of my head!

Travel would be easier, less expensive and less complicated. My garbage cans would be easier to get to the curb on garbage day. My mother-in-law (who doesn't adapt well to change) would just float away. Hmmm! After careful thought, I think it's a wonderful idea!! Bravo!

You proposition condradicts itself. If it is a "symptom of mass in motion," it still exists.

You may not be an accredited physics wiz, but I think your the Yoda of physics.
