Some Einsteinians know nothing about Master of the universe Stephen Hawking's discovery - that Michelson and Morley refuted John Michell - and publish awful things (should be kicked out of Einsteiniana immediately): http://www.springerlink.com/content/r3q22q7284331087/ Schwarzschild Radius Before General Relativity: Why Does Michell- Laplace Argument Provide the Correct Answer? Giovanni Preti Abstract A famous Newtonian argument by Michell and Laplace, regarding the existence of “dark bodies” and dating back to the end of the 18th century, is able to provide an exact general-relativistic result, namely the exact formula for the Schwarzschild radius. Since general relativity was formulated more than a century after this argument had been issued, it looks quite surprising that such a correct prediction could have been possible. Far from being merely a fortuitous coincidence (as one might justifiably be induced to think), this fact can find a reasonable explanation once the question is approached the other way round, i.e. from the general-relativistic point of view. By reexamining Laplace’s proof from this point of view, we discuss here the reasons why Michell-Laplace argument can be so “unexpectedly" correct in its general-relativistic prediction.

Michael Green is the new Lucasian chair of mathematics at Cambridge following in the footsteps of Newton and Hawking. (...) Furthermore, string theory, Green contends, "isn't simply something that will, once tested, be either verified or disproved. It's become much more than that". By the way, why does any Lucasian chair of mathematics at Cambridge become "Master of the universe"? http://www.guardian.co.uk/science/2008/mar/02/stephen.hawking Master of his universe. When Rachel Cooke was granted an interview with Stephen Hawking, she was told that he only had time to answer six questions. So what would you ask the scientist with one of the most acute brains of his generation? (...) The Department of Applied Mathematics and Theoretical Physics at Cambridge University, where Hawking is the Lucasian professor of mathematics, a post once held by Isaac Newton... The two-part series Stephen Hawking: Master of the Universe starts on Channel 4 on Monday 3 March I think I know why Hawking is Master of the universe - he discovered that Michelson and Morley refuted John Michell: http://www.hawking.org.uk/index.php?option=com_content&view=article&id=64&Itemid=66 Stephen Hawking: "Interestingly enough, Laplace himself wrote a paper in 1799 on how some stars could have a gravitational field so strong that light could not escape, but would be dragged back onto the star. He even calculated that a star of the same density as the Sun, but two hundred and fifty times the size, would have this property. But although Laplace may not have realised it, the same idea had been put forward 16 years earlier by a Cambridge man, John Mitchell, in a paper in the Philosophical Transactions of the Royal Society. Both Mitchell and Laplace thought of light as consisting of particles, rather like cannon balls, that could be slowed down by gravity, and made to fall back on the star. But a famous experiment, carried out by two Americans, Michelson and Morley in 1887, showed that light always travelled at a speed of one hundred and eighty six thousand miles a second, no matter where it came from. How then could gravity slow down light, and make it fall back." Yet I have no idea why Michael Green is Master of the universe - perhaps the enormous power automatically goes to any Lucasian professor of mathematics at Cambridge, even if he had not discovered that Michelson and Morley refuted John Michell.
