A fascinating talk about the composition of the universe [Youtube, approx 1 hour]
, presented by Sean Carroll
, theoretical physicist at CIT. [via]
His talk is fast-paced and high level, but has enough detail to get the imagination fired up. Topics include ordinary matter, the standard model, dark matter, dark energy, string theory, supersymmetry, and the expanding universe. The presentation is extremely coherent and easy to follow, even for non-theoretical-physicists such as myself. Enjoy.
