I was on a plane today thinking about recent research that uses vibrational/waves to interact with objects. Researchers can suspend and manipulate objects with these waves. I was thinking, why isn’t it possible to use this technology to create levitating objects or vehicles??? Like UFO type flight. Just attach powerful emitters around the craft. This article makes me think this might be possible. F= m*a If waves poss…

I guess the aviation application is very focused on the magnitude of the force generated per watt of power expended, and pushing really hard on air (like airplane engines do) is pretty effective for that, even if there's also some way to make sound waves generate thrust. Are the sound wave lifters and manipulators (which are super cool) very power-efficient compared to a fan or a jet engine?

Random idea this brings up... Some of the faster than light drive concepts worked by compressing space in front of the ship and expanding it behind. If sound waves carry mass maybe they could be harnessed and focused in a way to warp space time and impact travel speed? I wonder how the medium impacts the mass?

Here's one for ya ~> Which came first: Sound or light?

Which again proves Tesla's quotes about frequency and vibrations.

does light make sound?
