The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the big bang about 13 billion years ago.
ORIGIN late Middle English : from Old French univers or Latin universum, neuter of universus ‘combined into one, whole,’ from uni- ‘one’ + versus ‘turned’ (past participle of vertere).
universe noun 1 the physical universe cosmos, macrocosm, totality; infinity, all existence, Creation; space, outer space, firmament.
The part I accented bold is realy not a scientific truth at all, but a very persistent and very popular misconception.
The universe is not 'created' in the Big Bang. The Big Bang theory is only about the notion that the universe was denser, hotter and smaller in the past, and does not claim that the universe started from a singularity.
General Relativity predicts it's own break down at the singularity and is known to be incomplete, since quantum mechanical effects need to be taken into account.
