A wave exists only in its propagating medium but Einstein erred to discard the medium for ?light-wave' and introduce 4-D spacetime continuum. It denied him the chance to address wave-quantum Unity of light and to predict the existence of ?basic substance' to compose all forms of E & m so compellingly demanded by E=mc2, otherwise E & m could not interconvert. Unified Theory gives convincing arguments and experimental support for the existence of a real physical medium in space viz. 'sharmon medium' as the all-composing and all-pervading ?basic substance', which propagates light as a Wave-Quantum UNITY. The non-substantive abstract concepts of space & time arise from the perceptions of successive motions & changes in the surrounding objects and cannot fuse into any concrete spacetime continuum. All spacetime continua of 4 to 32 dimensions are non-existent mathematical constructs and theories based on them are unrealistic. Unified Theory explains Michelson-Morley & Sagnac experiments and constancy and invariance to source-observer motion of c, the two axiomatic postulates of Special Relativity, as also the observed variability of light velocity c and superluminality which invalidate Relativity. Lorentz formulae do not describe any natural velocity which varies (like v) with and is invariant (like c) to source-observer motion at the same time. And a real event, viewed by say, 100 differently moving observers cannot undergo 100 different objective alterations at the same time. This makes ?contraction of length' and 'dilation of time' unrealistic. Unified Theory explains Photoelectric Effect and Bending of Light in a Gravitational field. As against Relativity, no particle or energy quantum is massless or sizeless point.
