A really great primer by physicist Lawrence Krauss on what we have recently learned about the universe, how it is utterly dominated by "nothing", aka dark matter and dark energy, and why the emergent picture is so incomprehensibly bizarre.

I came across another super interesting lecture on topics very similar to what Krauss covers. It's titled, "Inflationary Cosmology: Is Our Universe Part of a Multiverse?", and was delivered by Professor Alan Guth of MIT, part of the Issac Newton Lecture, 2009.
Krauss is more entertaining and uses better visuals; Guth concentrates more on explaining the physics, which in his case also means less humor and fewer pot shots at religion.

Another related lecture, "Sean Carroll on the Arrow of Time", is worth watching. Carroll, a cosmologist, "gives an entertaining and thought-provoking talk about the nature of time, the origin of entropy, and how what happened before the Big Bang might be responsible for the arrow of time we observe today." Before the Bing Bang, huh?
