Third paper on the inverse relativity model, the first paper [1] included the splitting of total spacetime into positive and negative subspace-times, the second paper [2] included a description of relativistic mechanics in each subspace-time. In the third paper here, we study the properties, quantization and diagrams of each subspace-time and as a result we get the inverse length relativity where the length expands from the value zero to the original length in the negative subspace, inverse relativity of simultaneity where simultaneity is absolute and time is real and not an illusion in positive subspace, inverse relativity of time where time contracts to become supertime in negative subspace, inverse relativity of mass and kinetic energy where both are reduced in positive subspace. The paper also included new concepts of mass, work, and motion, An explanation of Heisenberg’s principle and discovering the existence of the inverse of the principle, and the quantization of transformation equations in each subspace. According to this quantization, we do not need infinite energy for a material particle to reach the speed of light in the special case, and there is no infinite energy density for a dust field in negative subspace in the general case. The structure of the negative subspace-time does not collapse when the speed of the reference frame reaches the speed of light, but the negative subspace-time turns into reverse subspace-time. We also propose in the paper a possibility for testing the model.
