Welcome 11th Dimension - The Elegant Universe - PBS NOVA Part 3 "The Elegant Universe" host Brian Greene shows Edward Witten Princeton' Institute Advanced Study, aided , revolutionized string theory successfully uniting versions single theory cryptically named "M-theory," development requires total eleven dimensions. Ten...eleven...' counting? But 11th dimension implies strings shapes called membranes, "branes" short. These science fiction- qualities, principle large universe. A brane universe— parallel universe— living . Witten string theory " part 21st-century physics fell chance 20th century." In fact, theory experimental technique verify strings real. But scientists CERN atom-smasher French-Swiss border working test predictions string theory. This experiment important step showing string theory crazy idea, crazy reality.
