The cosmological principle has first been clearly stated by Isaac Newton in the "Philosophiae Naturalis Principia Mathematica" in 1687. He proved with mathematical proofs on detailed observational data the principle of “universal gravitation”. The oscillating theory is a cosmological model which suggests that the universe we live in is a one of an innumerable series.
