Primarily because of the inability of the Physicists to explain the results of the Michelson Morley Experiment (MMEx) in the beginning of Twentieth century, the Special Theory of Relativity was accepted. It was then assumed that Light could travel in space as a wave-form, without the presence of any medium like Ether, and it would do so at the same constant velocity for all the observers traveling uniformly relative to each other in space. Both these presumptions appeared to be unreasonable by ordinary commonsense. It is however possible to explain the results of MMEx using the old classical Wave-Theory of light. When a mirror that is moving in the medium of space reflects light, the reflected frequency in the medium differs from the incident frequency in the medium, due to the Doppler effect. Further the reflected angle from moving mirror in the medium is also different from the incident angle in the medium, which in case of a static mirror are same. An observer who is static in the medium sees these changes, whereas an observer moving with the mirror will find that the incident and reflected frequencies and the angles remain the same. The two arms at right angles in the Interferometer of the MMEx are adjusted to be exactly the same length, but when it is moving in the medium, the two split light beams travel different path lengths, depending on the velocity of the equipment in the medium. The same velocity also causes Doppler changes in the frequencies. As a result though the two path lengths traveled by two light beams are different, the number of wavelengths covered in each path are exactly equal, at any velocity. So interference does not occur at all. This is fully calculated and explained in the Part 2 of the Article. An experiment to verify the existence of Ether in similar manner as MMEx is proposed; see Para 2.8.
The bound electrons in an atom have quantized energy levels, as amply demonstrated in Spectroscopy. But there is no real justifica-tion to assume that the Electromagnetic energy is quantized and it may be observed as a continuous wave-motion as well as quantized Photons. In Photo-Electricity the outer shell bound electron of an atom has very limited space around it to absorb adequate energy from an incident Electromagnetic waveform of lower frequency, irrespective of its intensity. Only a higher frequency will enable the electron to vibrate in the limited available space, to absorb sufficient energy, to leave the surface of the material. The waveform is continuous and not quantized, but the absorption of energy by the electron has to be of a minimum value for the electron to photo-emit. Similar explanations are given in the Article Part 2, of other observed phenomena, which can be explained using classical Physics and does not need any quantization assumptions. A model of Ether is proposed which though a continuum is linearly compressible when a material particle is embedded in it. Energy is stored in this compression. This Ether is capable of: 1) Storing the Gravitational Energy of the embedded material particles; 2) Permitting free movement of the embedded particles in accordance with the Newtonian Laws of Motion; 3) Storing the Kinetic Energy of the particle moving in it, relative to its original static condition; 4) Storing Electrostatic energy of a charged particle; 5) Storing Magnetostatic energy of a moving charged particle; 6) Transferring the Electromagnetic Wave energy at the constant velocity in empty Ether. This Ether has been explained in the Part 4. As this explains the storage and conversion of Gravitational, Kinetic and Electro-magnetic energy of a material particle in Ether, it may be considered to be a Classical Theory of Everything.
