Dark Energy: What Science Tells Us About the Hidden Universe

Bit of a long video this one but fascinating stuff if you’ve any interest in cosmology.

I do like the idea of “Science at the Theater”, there are loads of public lectures in London so I really should make an effort to see a few more.

Berkeley Lab’s Oct. 26 Science at the Theater event, “Dark Secrets: What Science Tells Us About the Hidden Universe,” was a smash hit: more than 600 people packed the Berkeley Repertory Theatre and over a hundred people had to be turned away.

No mystery is bigger than dark energy — the elusive force that makes up three-quarters of the Universe and is causing it to expand at an accelerating rate. Join a panel of Lawrence Berkeley National Laboratory scientists who use phenomena such as exploding stars and gravitational lenses to explore the dark cosmos.
