I dont know if this was posted before but Is it posible the theory of zero gravity points in earth?
The theory says that in ancient time the pyramids were located in one of this points that exist in simetrical points in the earth.
This points are the zones were are located for example the pyramids of the Incas, The pyramids in asia, stonehedge, The choral castle, Bermuda triangle, Dragon triangle, and ancient atlantis.
There are other points that are locations of military bases.
The theory says that in the last first of winter and the first day of summer (When the earth reaches maximum and minimum angle in its axis) there is a gravitational balance were with the apropiate technology you could make use of the zero gravity.
Of course I dont believe all this but the only thing they say it is scientifically proved are these electromagnetic “failure” points in the earth.
