Multiple Universes, Energized Space, and Thou, Whistling in the Darkness

Here is a quick and easy way to feed your brain today. It made my synapses all tingly. Go watch this video of physicist Lawrence Krauss.

I invited a group of cosmologists, experimentalists, theorists, and particle physicists and cosmologists. Stephen Hawking came; we had three Nobel laureates, Gerard 'tHooft, David Gross, Frank Wilczek; well-known cosmologists and physicists such as Jim Peebles at Princeton, Alan Guth at MIT, Kip Thorne at Caltech, Lisa Randall at Harvard; experimentalists, such as Barry Barish of LIGO, the gravitational wave observatory; we had observational cosmologists, people looking at the cosmic microwave background; we had Maria Spiropulu from CERN, who's working on the Large Hadron Collider — which a decade ago people wouldn't have thought it was a probe of gravity, but now due to recent work in the possibility of extra dimensions it might be.
