If you've ever imagined parallel worlds, alternate universes, or simultaneous realities which previously existed only in science fiction but are now part of the world of quantum physics you might find this interesting. Oxford Physicist David Deutsch author of The Fabric of Reality, an interesting read if you like to spend your spare time contemplating quantum theories of multiple worlds, speaks here at a TED.com conference. He poses that simple question What is our place in the Cosmos?
For those unfamiliar TED, it is an annual conference which brings together the world's most fascinating thinkers and doers and challenges them to give the most interesting talk of their lives...all in 18 minutes.
You don't have to be a physics grad student to enjoy his discussion on the wonder and amazing complexity of the universe. He talks about the world of knowledge now increasingly available at our fingertips, how unique this planet is in a mostly empty universe, the risk in denying the effects of global warming, and how we survive as a society when we know that every other past civilization in our current world basically disappears after a period of time.
