Suppose I built a sphere out of some non ferrous material such as wood or plastic with a door cut into it so I can open it and go inside. The sphere is about ten feet in diameter and is hollow inside. I then take a drill and drill equally spaced holes all around the sphere. Next I take some very strong bar magnets and glue them in the holes with all of the poles of the magnets the same direction and all pointed toward the center of the sphere. I then take a ping pong ball abd glue magnets to it equally spaced all around it with all the poles the same way but opposite the magnets in the big sphere. I then go inside the sphere and place the ping pong ball at the very center. Now provided all the magnets are strong enough, the ball should hang at the center of the sphere. (Compare this to the real universe where "an object at rest tends to remain at rest") If I give the ball a push it will break free from the center moving faster until it strikes the magnets at the inner edge of the sphere. Next I take the ball and remove all of the magnets from one hemisphere. I then glue the magnets back on the ball with all of the poles facing the other direction. When I place the ball at the center of the sphere it will no longer just hang there. One side of the ball will be pushing away from the magnets in the big sphere and the other side will be pulling toward. When I release the ball it should rapidly be pulled to the inner edge of the sphere. In one way it would be like a photon in that it would lose its rest mass. Now if I spin the ball and hold it at the center of the sphere and release it. It should fly away but now it is moving in a waving motion because of the spin. This is also like a photon because it is now in wave form. Since a photon behaves like my ping pong ball I was wondering if a photon has mass but the mass is concentrated on one side of the photon or to a point on one side of the photon. Or the pull of its mass is bent around to one side of the photon. Since whenever we have light there is usually a source of heat, I was also wondering if it is the heat that causes the photon to bend its mass to one side. (If it really works this way). However, in order for this to work the universe would have to be exerting a gravitational pull toward its center like the magnetic pull of my sphere. Also all mass would have to be located near the center of the universe. Anyone wonder what gives a photon its velocity and could this be a reasonable explaination?
