Black holes across the universe are losing enormous amounts of energy, and it could be due to magnetic fields slowing their spin. Understanding this process could help solve the long-standing mystery of how black hole jets are powered.
A new study of the supermassive black hole M87* has shown that the energy near its edge is flowing outward, not falling in. Scientists have long theorised that the magnetic fields…
