They have a gravitation field with lensing because whatever reactor/tech they have onboard is generating it, and they are are in a zero g space with no air friction which is why they don't make sound.

Their engines, whatever tech they use are directly controlling the quantum spacial points that make up the universe, through vibration.

This is the most important tech on earth.

It exists and works on earth because we literally have video proof of it and many eye witness accounts of black projects using its tech to fly without conventional engines, but we have no idea how its made as in the public. Someone has it, and it's being held secret. This is a greater problem than anything ever made. It would allow aircraft to travel in a zero gravity bubble warping time space using "infinite energy" and reach speeds faster than the speed of light.

So how would you theorize its made /sci/? Here's some resources.

No I don't want to talk about aliens, I just want to theorize on how this tech would work.
