  • The Theory of Relativity is an Error in Physics; the Speed of Light excludes the Laws of Optics

    The Theory of Relativity is an Error in Physics; the Speed of Light excludes the Laws of Optics Jozef Babiak Physicists measured the propagation of light in vacuum and matter through experiments with light over the course of several centuries. The Laws of Optics were derived from these measured results. The Laws of Optics were verified repeatedly via real experiments with light and used in the calculations of optical instruments that work properly. The Laws of Optics accurately define the…

  • The Doppler effect of spectral lines and shift of the frequency of light in space

    The Doppler effect of spectral lines and shift of the frequency of light in space Jozef Babiak The Doppler effect of spectral lines in space is the change in the frequency of light emitted by an illuminated celestial body, which moves closer or farther away from the Earth in vacuum. A description of the change in light frequency is realized with the assumption that an illuminated celestial body in vacuum moves closer or farther away from the observer in vacuum….
