Perhaps as we gain knowledge we build up Lifeforce/ether/EM substrate/Chi/Prana.
And utilization of knowledge corresponds to movement of Lifeforce, which causes ripples in the Lifeforce (which is the ether,) and these ripples are light.
If gravity as we understand it corresponds to movement of Lifeforce, then perhaps this is what the C's mean when they relate knowledge and gravity.
How can we demonstrate this gravitational energy? This is what intrigues me! The whole Jedi thing would be nice but I sense there is more to this than "psychokinesis".
A new twist on the biblical "Let There Be Utilization of gravity"
