(PhysOrg.com) -- A Harvard theoretical physicist has discussed with scientists at the Large Hadron Collider in Switzerland the possibility that they may discover a theorized "stau" particle, with a lifetime of a minute or so, that could provide the first experimental confirmation of string theory. http://www.physorg.com/news177262216.html Physics Thu, 12 Nov 2009 15:34:37 EST news177262216 Promising photonic devices, and theorists attempt to determine whether particle physics and string theory can be reconciled. http://www.physorg.com/news172732219.html Physics Mon, 21 Sep 2009 10:10:02 EST news172732219 Quantum mechanics and Einstein's theory of general relativity are both extremely accurate theories of how the universe works, but all attempts to combine the two into a unified theory have ended in failure. When physicists try to calculate the properties of a quantum theory of gravity, they find quantities that become infinite -- infinities that are so bad they can't be removed by mathematical gambits that work in other areas of physics. http://www.physorg.com/news169733869.html Physics Mon, 17 Aug 2009 13:18:47 EST news169733869 String theory has come under fire in recent years. Promises have been made that have not been lived up to. Leiden (The Netherlands) theoretical physicists have now for the first time used string theory to describe a physical phenomenon. Their discovery has been reported in Science Express. http://www.physorg.com/news166097923.html Physics Mon, 06 Jul 2009 11:19:17 EST news166097923 Since Galileo Galilei and Newton, the assumption is valid that inert and heavy mass are equivalent. This is, however, questioned by new physical theories such as the String theory. Now, the equivalence principle is put to test with so far unachieved accuracy within the scope of the "Microscope" space project -- a German-French cooperation. PTB (Physikalisch-Technische Bundesanstalt, Germany) has developed the manufacturing and measuring methods for the test masses. http://www.physorg.com/news161257625.html Physics Mon, 11 May 2009 10:47:34 EST news161257625 Several years after Duke University researchers announced spectacular behavior of a low density ultracold gas cloud, researchers at Brookhaven National Laboratory have observed strikingly similar properties in a very hot and dense plasma "fluid" created to simulate conditions when the universe was about one millionths of a second old. http://www.physorg.com/news153928950.html Physics Sun, 15 Feb 2009 14:03:22 EST news153928950 Here's what didn't happen on Sept. 10th:The world did not end. Switching on the world's largest and most powerful particle accelerator near Geneva, Switzerland, did not trigger the creation of a microscopic black hole. And that black hole did not start rapidly sucking in surrounding matter faster and faster until it devoured the Earth, as sensationalist news reports had suggested it might. http://www.physorg.com/news143211630.html Physics Tue, 14 Oct 2008 14:00:30 EST news143211630 What do black holes and entangled particles have in common? Until about a year ago, physicists thought that the two entities existed in completely separate worlds. Then, in 2007, physicist Michael Duff from Imperial College London demonstrated a correlation between the entanglement of three qubits and the entropy of a black hole. In the past year, several studies have demonstrated even more connections. http://www.physorg.com/news134303818.html Physics Thu, 03 Jul 2008 11:36:58 EST news134303818
