It is generally accepted that in an electron-free hydrogen atomthe proton oscillates between physical vacuum(PV) and baryonicmatter. This oscillation causes a stationary spherical shock wave (SSW) around the proton in PV. For a stationary spherical shock wave, the name Âelectronic orbitalÂ is not correct. Based on our experimental data the SSW radius was calculated to be 5.3.10-11 m and equals the Bohr radius. SSW was characterized by multiple energy levels. We propose that the electron does not exist, but instead can be described as a stationary spherical shock wave resulting from proton oscillation.
