Czech scientists describe new type of spherical black hole

Scientists from the Faculty of Mathematics and Physics of Prague's Charles University and the Czech Science Academy's (AV) Institute of Mathematics have found the solution to "quadratic gravity" and described a new type of a spherical black hole, the AV said in a press release on Wednesday. Their research, which followed the numerical simulations by an international team of scientists, was published in the Physical Review Letters journal. The well-known Schwarzschild black hole is characterised by its weight only, while the new black hole is also described by the value of the Bach tensor on the horizon, which is a quantity influencing the movement of objects going round this hypothetic black hole. It thus causes potentially measurable deviations from the classical Einstein's Gravity.
