Lawrence Krauss: A Universe From Nothing

28/04/2010

Christopher Hitchens has recommended this lecture several times in recent debates.  That was all the advice and reassurance I needed to check it out and I was not disappointed.

“The Woody Allen of physics” (as Richard Dawkins dubbed him at the lecture’s end) delivers a wonderfully lucid and humorous account at the Atheist Alliance International conference 2009 of how physics can answer the infernal question posed by religious apologists as to why there is “something” rather than “nothing” for the layman.

Every atom in your body came from a star that exploded.  And, the atoms in your left hand probably came from a different star than your right hand.  It really is the most poetic thing I know about physics.  You are all stardust.  You couldn’t be here if stars hadn’t exploded, because the elements – the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life – weren’t created at the beginning of time.  They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode.

So, forget Jesus.  The stars died so that you could be here today.

I wish Krauss had been my secondary school physics teacher.
