As Minkowski space splits into positive and negative space (we mentioned this in the second paper "Modified Lorentz transformations and Minkowski space splits in inverse relativity") The energy of the photon and the relativistic kinetic energy of the particle are also analyzed into positive and negative energy, and each type has its properties through the geometrical properties of the space in which it is located, where we find that the energy in the positive space decreases due to dilation of time and It is causally related to observers and their observation devices, so it can be observed, while energy in negative space is causally separate from observers and their observation devices, it cannot be observed, And when the speed of the reference frame reaches the speed of light, theoretically, the positive energy reaches zero and the negative energy reaches infinity, The paper also includes a geometric visualization of the rest mass energy through a new hypothesis known as the dimensional rest energy
