Phonons, phonons, phonons are they gravity particles? They are then two types of phonons corresponding to positive gravity particles and negative gravity particles. When spinning they will manifest an electric field or a temperature field. Both are weak and transient fields. By themselves, they increase or decrease gravitational potential. It would then be possible to displace the center of gravity of some geometric shape by setting off one particular type of phonons in one direction.
Have a nice day.
