Which of the following has not yet been proven but will add support to the Big Bang Theory if true?

 the universe is expanding

 overall density of ordinary matter must be roughly 4% of the critical density

 there is an abundance of the light elements H, He, Li

 there is widespread cosmic microwave background (CMB) radiation
