There are two types of models: and Steady State. However, through many observational evidences, the theory can best explai ....

.... observed. The Steady State model says that the universe does not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the model is more reasonable than the Steady State model. First, t ....
