This is what I have coined a APS or Acoustic Propelled Spacecraft. Could this be how Aliens fly UFO's? No need to be mean on this post. Lets just try
and make this work. Why wouldn't this work and how could that be overcome?
The outer shell moves independent of the centralized core of the ship. It is free moving and only connected slightly on the top yet still allows free
motion. The Inside of the ship is all connected. The Acoustic sound generator is located below. It provides enough thrust internally to equal out
gravity or to counter it all together. This is controlled by the level of the acoustic tone used. The fact that the ships shell is independent of the
central core allows for the high speed spinning of the ships. The outside spins while the interior remains still. These same acoustic forces can be
used to fight the struggle of G forces allowing for very high transport speed and little to no discomforts during travel. The interior chamber is
filled with a transportation vessel for the acoustic force while in space. The Power source is located in the interior of the grand chamber where
occupants reside.
