“EVERYTHING THAT IS INTERSTELLAR IS INTERDIMENSIONAL”, Dr Steven Greer
Why has there been such a secrecy maintained by the US government on the ET’s presence and contacts for almost a century?
The answer is: Energy. Free universal energy.

The ET’s spaceships move from their own galaxies to our planet and back by shifting dimensions, and they do not burn fuel, of course. They use free energy, and that is the big secret the governments and powers that be do not want us to know.
