    : Physics Buzz Physics Fun and Science News . Socks Optional Brought to you by PhysicsCentral.com Wednesday , September 01, 2010 An experiment to test string theory Michael Duff , a professor at the Imperial College in London , was at a conference in Tasmania watching a colleague give a talk on quantum entanglement when he realized the equations being presented looked rather similar to a set of equations he had created to describe string theory inside black holes . When he returned to London , he checked the formulas against each other and discovered that not only were they similar , but the equations were in fact the . same It's now thought that Duff's discovery might allow physicists to predict the behavior of entangled quantum particles with string theory .

    Updated: 2010-07-31 02:26:36
     o i was thinking about how scientists say that the expansion of the universe is accelerating over time. and i thought about what else has been happening over time: black holes sucking up matter. there was another thread recently that asked if our universe came from a black hole in another universe. what if black holes lead to another dimension instead (one of the 11 we supposedly have). theory says that a black hole crushes matter to a singularity, right? what if all that matter is being crushed into another dimension? and the effect of this is dark energy. the more matter that gets sent to this other dimension, the stronger effect it has. hence, expanding acceleration. any takers?

    Updated: 2010-07-14 01:03:48
    Could the magnetic pinch of the polar jets funnel Hawking Radiation through the interaction of magnetic field lines? To explain the reason for this question is, if black holes can have a spin in excess of "C"  nbsp;momentarily, s a result of an ncrease in angular momentum, could possibly orm an event horizon between the two hemispheres, which ould ossibly produce  Dirac String coupling between the two magnetic moments through the singularity between the two hemispheres of the black hole. Just think about it.
