It is considered the model of the homogeneous and isotropic universe . The scale of length is defined via the laboratory scale of time by the motion of photon . This leads to the appearance of the inertial forces . The properties of the space and time are defined both by these inertial forces and by the matter . Within the framework of classical physics , the scales of length , time and mass are related by the special relativity constant c and by the Newton gravity constant G . Within the framework of quantum mechanics , the scales of length , time and energy are related by the special relativity constant c and by the quantum mechanics constant \hbar . The model meets constraints from the current age of the universe , from the high-redshift supernovae data , and from primordial nucleosynthesis . The model predicts the fractal galaxy distribution with a power index of 2 .
