Mysteries

Tests have shown that acoustic resonance using a particular frequency 160 mhz has a negative gravity effect, but this has only been demonstrated with very small objects. Could this be how huge stones were transported and lifted thousands of years ago? However the anti-gravity effect is achieved to lift an object, force still has to be applied to move it sideways.
