Einstein's Lost Model of the Universe Discovered 'Hiding In Plain Sight'
Hugh Pickens DOT Com writes "Dick Ahlstrom reports that Irish researchers have discovered a previously unknown model of the universe written in 1931 by physicist Albert Einstein that had been misfiled and effectively "lost" until its discovery last August while researchers been searching through a collection of Einstein's papers put online by the Hebrew University in Jerusalem. "I was looking through drafts, but then slowly realised it was a draft of something very different," says Dr O'Raifeartaigh. "I nearly fell off my chair. It was hidden in perfect plain sight. This particular manuscript was misfiled as a draft of something else." Read more, below. "In his paper, radically different from his previously known models of the universe, Einstein speculated the expanding universe could remain unchanged and in a " steady state" because new matter was being continuously created from space. "It is what Einstein is attempting to do that would surprise most historians, because nobody had known this idea. It was later proposed by Fred Hoyle in 1948 and became controversial in the 1950s, the steady state model of the cosmos," says O'Raifeartaigh. Hoyle argued that space could be expanding eternally and keeping a roughly constant density. It could do this by continually adding new matter, with elementary particles spontaneously popping up from space. Particles would then coalesce to form galaxies and stars, and these would appear at just the right rate to take up the extra room created by the expansion of space. Hoyle's Universe was always infinite, so its size did not change as it expanded. It was in a 'steady state'. "This finding confirms that Hoyle was not a crank," says Simon Mitton. "If only Hoyle had known, he would certainly have used it to punch his opponents." Although Hoyle's model was eventually ruled out by astronomical observations, it was at least mathematically consistent, tweaking the equations of Einstein's general theory of relativity to provide a possible mechanism for the spontaneous generation of matter. Einstein's paper attracted no attention because Einstein abandoned it after he spotted a mistake and then didn't publish it but the fact that Einstein experimented with the steady-state concept demonstrates Einstein's continued resistance to the idea of a Big Bang, which he at first found "abominable", even though other theoreticians had shown it to be a natural consequence of his general theory of relativity." -
University Makes 80,000 Einstein Documents Publicly Available
orgelspieler writes "The Hebrew University of Jerusalem has scanned in some 80,000 of Albert Einstein's documents. According to the university's press release, the documents cover more than just scientific matters. The broad range of subjects include his solution to the Jewish-Arab conflict, a postcard to his mother, and a letter from one of his mistresses asking for assistance getting to America. Some documents have been translated and annotated and are completely searchable." -

Getting Inside Einstein's Head
su-geek writes "'The most incomprehensible thing about the world is that it is comprehensible,' Albert Einstein once remarked. Today many scientific documents and personal papers detailing the thoughts and emotions of our favorite physicist will be available at 3PM EST you can access the Einstein Archives Online. Also, Wired is running an article"
