Variable Gravity

This is an interesting read. It puts forward the idea that gravity of a given mass is not a constant but instead alterable by external stimulus. If this is the case, many things in mankind's past make a lot more sense all of the sudden. The extinction of the large dinosaurs when gravity increased for one. What was gravity when the great pyramids, or stone hinge were being built (Just a thought.)? There's also the idea that our current solar system is a compilation disk. This and this attempt to explore the idea. If gravity is variable based on the electric field strength a planet exists in, than merging with a solar system that has a stronger current source and larger current load would definitely cause a change in gravity.
