I constantly hear 'things' about us having ancient portal devices. This is what I have heard. Area 51, in the hanger in the mountain where the antique UFO's are kept, is a room with a C shaped ring in it. A section is out, designed that way, and it has like 8 magnet gyros in it, along the perimeter. It lays flat on the ground, and when you crank it up, it tares a hole in space, time, via gravity from the gyro magnets.
This is supposedly the 'real' Stargate, and it was ancient Babylonian instead of Egyptian, and it was from ancient Babylonian text (a particular script) that they were able to figure out how to make it link to other portals. The military call them 'portals', (not gates). Supposedly there are some all over the Earth and then on other planets, and according to one story of a man who kept an alien healthy at Area 51, they can link to other worlds outside of our solar system, as the one alien 'went back home' through a gate at another location here on Earth.
From what I understand, the USAF can 'portal' to Mars. A USAF General is quoted as saying that it is 'safer and faster' to portal then to use space craft, etc.
And according to what I hear about Mars, the US has a base there they is designated as a 'defense missle base' and its there to protect the 'people' (race of Martians that have always been there) from alien invasion.
It sounds pretty far out at first, but if you keep hearing the reports from different sources, they all corelate to specific details. They all link up. Supposedly, for instance, one gate is/was at Abydos Egypt. In the movie Stargate, Abydos is another world, the first one we go to.
There are even details on the 'lobby' of this hanger/bunker where the gate program is located, which is in the mountain side.
Sadly, all secret. Dont you wish they had those antique saucers on display at a big museum instead of hidden away. How awesome it would be to study those things. Why couldnt they be at the Smithsonian Museum.
But, anyways, that is what I have heard from many many sources. Take it with a grain of salt, I always say. I am sure some details are lies designed to get us off course, etc.
