If you input a electrical frequency or a sound frequency and change the gravity of a particle then the destruction of that particle may explode or the particle may divide into smaller parts of it's self that is into individual atoms thus changing the gravity of the particles that are left.
The energy to do this is minute. Could you believe how this could change medicine and engineering into the future, time travel is like a mass of clouds swirling in the sky. It is an orgasmic eruption in the universe free to everyone.
The trouble is to reassemble the particles into the same order as when the reaction started.
