Speed Affected by Gravity All objects with mass have gravity. So what if a tiny particle accelerating in a cyclotron cannot reach the speed of EMR because it's gravity is being emitted at that speed? Sort of like the old aircraft designs had trouble piercing the shock wave of a sound barrier. As the particle accelerates the gravity being emitted is more and more compressed creating resistance. I know it's a crazy theory and the common belief is that gravity is an affect caused by matter warping space/time around it. Just an idea.
