One was Fred Hoyle's steady state model , whereby new matter would be created as the universe seemed to expand. In this model the universe is roughly the same at any point in time. The other was Lemaître's Big Bang theory, advocated and developed by George Gamow , who introduced big bang nucleosynthesis ( BBN ) and whose associates, Ralph Alpher and Robert Herman , predicted the CMB . Ironically, it was Hoyle who coined the phrase that came to be applied to Lemaître's theory, referring to it as "this...
