Space waves
We know from quantum mechanics that particles of matter are in constant vibration. In our academic physics this vibration has no impact on space. This action remains without reaction. This is an axiom of modern physics and it must be false.
It is a physical impossibility for matter to come into contact with space without vibrations having an effect. Based on the Casimir Effect and other physical phenomena we can state that space exists in waves and vibrations. Space waves.
Mass creates space waves. The wavelengths of space wave depends on the velocity (or density) of mass. Faster mass, longer wavelength.
