The prevailing model for the evolution of the Universe is the Big Bang theory.[34][35] The Big Bang model states that the earliest state of the Universe was extremely hot and dense and that it subsequently expanded. The model is based on general relativity and on simplifying assumptions such as homogeneity and isotropy of space
