David Sereda presents his theory about UFOs. I picked out some points he talks about (Watch the video to understand it fully):

UFOs can become massless. If they had mass at certain high speed maneuvers like instant 90° turns g-forces would destroy them.

UFOs do not use anti-gravity. If they did, they still would have mass, thus underlie g-forces. See above.

UFOs can become invisible. That is, to the human eye — which is limited to wavelengths between 400 nm and 700 nm. Ultraviolet capable cameras recorded UFOs in seemingly empty space.

That also means that UFOs do not come from other dimensions when they suddenly appear or go to other dimensions when they disappear — they just go into a state where they do not emit light in wavelenghts visible to the human eye.

UFOs can fly lightspeed and faster. In this presentation David Sereda explains how that can be possible. He explains it more detailed in that video.

Wormholes are no plausible approach for travelling vast distances in space because creating a wormhole the size of a quarter takes an amount of energy equivalent to the output of 100 million suns over a year.

Footage used in this presentation includes among others:

  • Official NASA recordings showing UFOs gathering, flying in formations and appearing or disappearing directly in front of the cameras
  • Interview with Gordon Cooper, former American austranaut, talking about his encounters with UFOs

Note: The video screen is black the first 30 seconds. In the Question & Answer part the video just shows a slide for several minutes instead of David Sereda standing at his lectern.
