The Big Bang Hubble's discovery that the universe (1) (expand) lent weight to a hypothesis that (2) (put forward) in 1927 by a Belgian priest, Georges Lemaître. He (3) postulated (postulate) that all the matter in the universé (4) (spring) from a single source, now called a 'singularity' - a point so small it (5) (have) no dimensions - and that at some indefinably minuscule slither of time approximately 13.7 billion years ago, all this matter. (explode) outwards from its source in a massive blast - so massive in fact that it (7) (still go on), and the universe (8) ever since. The term 'The Big Bang' (9) (6) (expand) (coin) some time later by scientist Fred Hoyle, who, at the time (10) trid (try) to criticise the hypothesis, but it (11) (stick), and now this (12) is (be) the idea that most scientists seem to favour.
