Program Description

Eleven dimensions, parallel universes, and a world made out of strings? It's not science fiction, it's string theory. Bestselling author and physicist Brian Greene offers a tour of this seemingly strange world in "The Elegant Universe," a three-hour Peabody Award-winning miniseries.

Part 1, "Einstein's Dream," introduces string theory and shows how modern physics—composed of two theories that are ferociously incompatible—reached its schizophrenic impasse: One theory, general relativity, successfully describes big things like stars and galaxies, while another, quantum mechanics, is equally successful at explaining small things like atoms and subatomic particles. Albert Einstein, the inventor of general relativity, dreamed of finding a single theory that would embrace all of nature's laws. But in this quest for the so-called unified theory, Einstein came up empty-handed, and the conflict between general relativity and quantum mechanics has stymied all who've followed. That is, until the discovery of string theory.

  • wow cool stuff !

  • You guys are awesome! I love you guys. Having said that, these scientists are mistaking "time" (perception of events), with existence.

    they need extra spacetime to account for perception/consciousness. Suppose spacetime was static. Not expanding or contracting. Just suppose. One could still have an infinite amount of "now" slices with different events happening in each slice and no extra spacetime. The "loaf of bread" doesn't grow. They are slices of consciousness(now) over the same spacetime!

  • this show is incredible, thanks for the upload
