How Did the Universe Begin

Only a man with the brain the size of Stephen Hawking’s would seriously accept the challenge of answering the question How did the universe begin? in less than 30 minutes, while making it accessible for the population at large.

Hawking’s lecture is a masterclass in concision and clear thinking. He spins through the history of thought on the subject, beginning with the early Biblical view that the world was created by God around 6,000 years ago. And that wasn’t the only cockamanie theory dreamt up in the succeeding millennia. Up until the 20th century, mainstream thinking viewed the universe as eternal, a static expanse that had no beginning or end, and where, as Hawking supposes, “nothing very exciting ever happened”.

Hawking himself, of course has been instrumental in overturning many of the fallacious propositions about the origin and development of the universe, disproving (in his PhD thesis, for God’s sake) the “bouncing” theory, which proposed that the universe expanded and contracted infinitely over time.
