This came across my mind today, I am not sure if it's been proposed/invalidated before. I don't have enough physics background to prove or disprove it so I came here for input: Imagine if some energy packets were constantly and uniformly emanated at the speed of light from the edge of the universe from all directions. Assume such an energy packet would exert a directional force on any mass/energy particle upon impact, and then lose the energy. In a universe of finite size, the following would be observed: 1. a stationary mass particle at the center of the universe would receive equal pressure from these energy packets from all directions, and thus remain stationary. 2. a stationary mass particle at the edge of the universe would receive more energy packets from the direction opposite to this edge of the universe, and therefore the mass particle would move away from the center and towards this edge of the universe. (explains "expansion" of universe at edge) 3. back to the stationary mass particle at the center of the universe, now let's spontaneously introduce a huge mass body near this stationary particle, the following occur: a. mass particles in the mass body block energy packets coming from this side of the stationary mass particle, therefore, energy packets from the other side push the stationary particle towards the mass body. b. the effect of this spontaneous introduction travels at the speed of light because the energy packets that were already in between the mass body and the mass particle weren't blocked and continued at the speed of light towards the mass particle maintaining a temporary equilibrium. (explains why gravity travels at speed of light) 4. The "weight" of an object is then really the delta pressure between energy packets pushing from one side and energy packets pushing from the other side. Therefore for something/someone to get "crushed" by two bodies, enough mass particles need to exist on both sides to allow the energy packets to transfer the force, the more mass the more force is transferred. 5. #2 and #3 act against each other, at the center, #3 wins out, and at the edge #2 wins out. However, eventually, everything other than at the dead center will drift out towards an edge (assuming uniform); if non-uniform, any random drifts can happen at or near the center. Any fallacies in this interpretation? has it been proposed before? if so where can I read about it?
