Theoretical Background

Theoretical background of T.T. Brown Electro-Gravity Communication System

The article describes communication system working on base of gravity waves. Such system of devices should work if the electromagnetic field curves space-time. Theoretical results shows that the artificial change of gravity of space-time curvature should observes in the distance much more bigger than dimension of transmitter antenna. The article end with discussion of details of technical prope...
