A discovered relativistic Photon-Atom-Energy paradox led to a solution, according to which the Planck constant is to be treated relativistic, whereby a new relativistic effect and a fourth relativistic attribute was discovered. Nevertheless it stays invariant in Lorentz transformations. The same result was derived in another way and motivation using same new method. A second problem was discovered by analysing Planck mass, length and time relativistically. This does lead to a discovery of 4 more paradoxes of Special Relativity, which were solved by same relativistic Planck Constant. Testing new method on speed of light we discovered that in SRT it is not kept invariant but depends on Lorentz factor, so it contradicts own 2-d postulate. This is a logical failure in SRT due to inconsistent using length units and measurements and is irreparable. To solve that was necessary to assume that length too as time has to be stretched or dilated in its length unit. Longer length units as longer time units allow to measure contracted distances and time lines due to viewer number of longer units fitting between two space locations. At the end all now 4 relativistic attributes length, time, mass and Planck constant are asymmetrically between the Inertial Frames and do build an unified Level Relativity. All dispute is very vividly and easy for understanding without high mathematics. If we decline the square relativistic Planck constant then all 5 discovered paradoxes would stay irreparable in Special Relativity.
