Relative Universe, a special theory of gravitation
Teguh Waluyo · 2023
Gravitation is the relative density of space-time caused by the mass of an object. There are three aspects of gravitation. First, it is related to an object. Gravitation can cause changes in the velocity of an object. Second, it is related to a photon, gravitation can change the frequency of a photon. Third, it is related to differences in the result of observation. Different observers of the same object can yield different results. Gravitation causes differences in the period of an event, differences in the length of an object, and differences in the mass or energy of an object.
