00:04rotating black holes can produce immense amounts of energy energy mankind has of course thought
00:09about harnessing but the problem with black holes is that when anything passes the cosmic
00:13body's event horizon it can never get out even light gets trapped however experts now say that
00:19energy may be able to be extracted from a black hole's ergosphere or an area just outside a black
00:23hole's event horizon it turns out gamma ray burst grb 190114c is the key to understanding how gamma
00:31ray bursts are released when a star goes supernova or when one implodes and becomes a neutron star or
00:36a black hole gamma ray bursts are the most energetic electromagnetic events ever observed and now
00:41experts from the international center for relativistic astrophysics network in italy believe they may now
00:46understand how they are ejected from black holes black holes inherit magnetic field lines from their
00:51parent neutron star as the black hole spins particles are accelerated along those lines
00:55speeding up and eventually getting jettisoned into space by means of a quote purely general relativistic
01:01gravito-electrodynamical process all coming from the ergosphere and in grb 190114c's case
01:08producing an insane cosmic flare an energetic phenomenon containing a trillion electron volts
