A New Light on the Nature of Light
The Quantum Theory and Special Relativity stand apart because their authors were admittedly unclear about natures of light and light propagating medium. However, a single experiment shows wave-quantum unity for low intensity light and moving electrons. In Unified Theory light is emitted and absorbed as 0-spin sharmon composed energy-quantum hυ and is propagated as one cycle EM pulse one λ long and of duration t = 1/υ with a crest and a trough carrying energy quantum hυ as a Wave-Quantum UNITY as per Poyinting vector in the physical 'sharmon medium' contiguously via 1-spin sharmons, which do not physically move. It appears as Quantum Theory's wave-or-quantum DUALITY for observing only one of the two not both characters at a time. Sharmon medium is all-composing, all-pervading and irremovable, ruling out absolute vacuum. It has 1015 sharmons/cm3; its inter-sharmon distance 10−5 cm compares with mean free path of real gases. Sharmon comprises a positive positrino and a negative negatrino, the two non-composite, indivisible elements of dia. 1.6x10−33cm, electric charge 1.3729x10−30 esu, mass 2.596116x10−48 gm, spin = 1/2. These two compose all forms of mass, energy, energy quanta like photon and particles like quarks, leptons and hadrons in the Cosmos hence named ?cosmino‟. Particles can move faster than light. Copenhagen interpretation of Quantum Theory is reviewed. Uncertainty Principle is replaced by the new Principle of Null Action based on the conservation of mass-energy, momentum and action. Lorentz transforms do not describe any natural motion. 'Contraction of space' and 'dilatation of time' are unrealistic demands on Nature to fit mathematics of Special Relativity. Constancy and invariance of light velocity c are explained, as also the observed variability, superluminality and subluminality which invalidate Relativity theories. Spacetime continua, Higgs boson and conventional ?photon‟ are nonexistent. One cycle EM pulse explains photoelectric effect and bending of light under gravity. Michelson-Morley got zero fringe-shift as light velocity in the sharmon medium entrained with earth is the same for both perpendicular interfering beams. Maxwell equations are derived from Sharmon Medium. Non-Doppler cosmological redshift supports non-expanding universe, contesting conclusions of 2011-Physics Nobel laureates.
