Unexpected magnetic field challenges everything we know about black holes


Astronomers are puzzled by a strange stream of particles shooting from a black hole. The unusual flare observations contradict current models of black holes and their powerful magnetic fields, which can jeopardize everything we know about these mysterious regions of space.

Published today in Science data from the black hole system V404 Cygni suggest that magnetic fields are much weaker than physicists believed. To account for this research, black hole theories must be rewritten.
