Professor Stephen Hawking Takes Zero-Gravity Flight
1:07
ZERO-G(TM) and its sponsors, Space Florida and The Sharper Image, flew world-renowned physicist and cosmologist Professor Stephen Hawking into weightlessness today, performing eight parabolas, out of the Shuttle Landing Facility at the Kennedy Space Center in Central Florida. It was the first time Professor Hawking, the world's leading expert on gravity, had a zero-gravity experience. タグ:stephenzerogravitykennedyspace 投稿日: April 27, 2007, 12:13 pm 閲覧数: 314460 投票: 4.80(５点満点) 693 人の平均
Stephen Hawking, Black Holes, and The Creator
10:07
Hawkings reverses his 30 year old theory that black holes destroy matter, and seeks to show convincingly that alternate universes exist without black holes. Again, God's ways are past finding out. タグ:stephenblackholestheoryscience 投稿日: January 28, 2007, 5:28 pm 閲覧数: 204591 投票: 4.60(５点満点) 567 人の平均

Stephen Hawking: Asking big questions about the universe
10:13
http://www.ted.com In keeping with the theme of TED2008, professor Stephen Hawking asks some Big Questions about our universe -- How did the universe begin? How did life begin? Are we alone? -- and discusses how we might go about answering them. タグ:stephenscienceuniversetedtedtalks 投稿日: April 5, 2008, 12:03 am 閲覧数: 165431 投票: 4.70(５点満点) 1174 人の平均

Prof Stephen Hawking speech to Campus Party 2006
Hawking's principal fields of research are theoretical cosmology and quantum gravity. In 1971, in collaboration with Sir Roger Penrose, he proved the first of many singularity theorems; such theorems provide a set of sufficient conditions for the existence of a singularity in space-time. This work showed that, far from being mathematical curiosities which appear only in special cases, singularities are a fairly generic feature of general relativity.
Hawking also suggested that, after the Big Bang, primordial or mini black holes were formed. With Bardeen and Carter, he proposed the four Laws of black hole mechanics, drawing an analogy with thermodynamics. In 1974, he calculated that black holes should thermally create and emit subatomic particles, known as Hawking radiation, until they exhaust their energy and evaporate.
In collaboration with Jim Hartle, Hawking developed a model in which the Universe had no boundary in space-time, replacing the initial singularity of the classical Big Bang models with a region akin to the North pole; while one cannot travel North of the North pole, there is no boundary there. While originally the no-boundary proposal predicted a closed Universe, discussions with Neil Turok led to the realization that the no-boundary proposal is consistent with a Universe which is not closed also. タグ:stephenuniversityofcambridge2006 投稿日: August 13, 2006, 9:34 am 閲覧数: 25604 投票: 4.70(５点満点) 73 人の平均
