A simple and clear concept, at least according to the hypothesis by Roy Kerr, who in 1963 proposed a "clean" black hole model, which is the current theoretical paradigm. From theory to reality things may be quite different. A very special cosmological model based on the dynamical interior geometry of a Black Hole is found that has no singularities at t = 0 due to the smoothing of the mass distribution. Spinning black holes (called Kerr black holes, after the New Zealander physicist Roy Kerr) can exist in two states: one in which they heat up when they lose energy (negative specific heat), and one in which they cool down (positive specific heat). Aug 27, 2008 - The Kerr-Newman black-hole entropy as well as the Reissner-Nordstrom, Kerr and Schwarzschild black-hole entropy are derived from the corresponding Euclideanized actions. As described by the Kerr solution of Einstein's gravitational field equations, its spacetime geometry is . Jan 27, 2014 - Most physicists foolhardy enough to write a paper claiming that “there are no black holes” — at least not in the sense we usually imagine — would probably be dismissed as cranks. Do you answer the doorbell/let someone in your place when your house is not exactly ship-shape? Apr 23, 2007 - Does this mean that if the direction of the spin of the accretion disk of a rotating ("Kerr") black hole is reversed it will start ejecting energy instead of absorbing? According to a new research carried out by a group of scientists . Like, "Huh, that wall looked clean but eeeww why is this sponge black? Aug 22, 2010 - (1965)1 quickly generalized Kerr's solution to a black hole that has both charge and spin. Nov 13, 2012 - Testing the space-time geometry around black hole candidates with the analysis of the broad K$\alpha$ iron line. Aug 21, 2012 - Second, when Plato wanted to discuss the cosmos as a whole in his celebrated Timaeus, he chose the dodecahedron (Figure 2) as the shape “which the god used for embroidering the constellations on the whole heaven. We need to explore Kerr-Newman solutions of the Einstein-Maxwell equations empirically, rather than theoretically. Hole has been described as one of nature's most perfect objects. Mar 7, 2014 - The first is to remove the speaker cover--generally, just wiping the speakers down will remove dirt and debris, but when you're talking about vomit that can get stuck in all those tiny holes you'll probably want to do a deeper cleaning--so you can either submerge them in a cleaning solution . At that point, whatever was once trapped within the black hole would be released (although not in good shape).
