Gravity Restatement

Archive for December 2010

Consider the first schematic diagram. It represents gravitational mass displacement at work. At left is a massive gravity object, such as a large galaxy. A less massive galaxy (right) is moving toward the gravity object. Both galaxies have super massive black holes at center.

Two imaginary lines (green) represent a starting line and finish line for two photons, shown in red. Both photons cross the start line simultaneously, one (bottom) emitted from an outer star in the galaxy, the other emitted from a star near the center. Great distance separates the photons, at least a thousand light years.

Consider the second schematic diagram. The less massive galaxy is accelerating toward the gravity object and pulling the nearby photon with it. The photon near galaxy center reaches the imaginary finish line first. It wins!

Were humans to place a particle accelerator near the center of the less massive galaxy to accelerate a particle to 99% of light speed, that particle would travel faster than the distant photon, as long as the black hole at center had a speed of greater than 1% of light speed. The particle would move in a manner analogous to the photon (first diagram).

This in no way violates E=mc^2.
