They knew that magnetic fields probably extract energy from spinning black holes– they simply didnt understand how.A group of Princeton astrophysicists has now figured out conclusively that energy close to the event horizon of black hole M87 * is pressing outward, not inward.”Our new, sharp prediction is that whenever you look at an astrophysical black hole, if it has magnetic field lines connected to it, there will be energy transfer– truly insane amounts of energy transfer,” said Lupsasca, a former associate research study scholar at Princeton who is now an assistant professor of physics and mathematics at Vanderbilt University, and who won the 2024 New Horizons in Physics Prize from the Breakthrough Prize Foundation for his black hole research.While the energy flow close to M87 *s event horizon is streaming outwards, the group said that the energy circulation might in theory go inward in a various black hole. They are confident in their link between energy flow and the instructions of the magnetic field lines, and their prediction that the energy flow comes from the black hole will be tested with the launch of the still-theoretical “next generation” Event Horizon Telescope.For the previous year and a half, black hole scientists around the world have been proposing specs for the future instrument, Wong said.

Young Professor of Astronomy on the Class of 1897 Foundation. They understood that magnetic fields probably draw out energy from spinning black holes– they just didnt understand how.A group of Princeton astrophysicists has actually now determined conclusively that energy close to the occasion horizon of black hole M87 * is pushing outside, not inward.”Our new, sharp prediction is that whenever you look at an astrophysical black hole, if it has magnetic field lines connected to it, there will be energy transfer– really ridiculous quantities of energy transfer,” said Lupsasca, a previous associate research scholar at Princeton who is now an assistant professor of physics and mathematics at Vanderbilt University, and who won the 2024 New Horizons in Physics Prize from the Breakthrough Prize Foundation for his black hole research.While the energy flow close to M87 *s event horizon is streaming outwards, the group said that the energy circulation might in theory go inward in a various black hole. They are positive in their link in between energy flow and the direction of the magnetic field lines, and their forecast that the energy circulation comes from the black hole will be tested with the launch of the still-theoretical “next generation” Event Horizon Telescope.For the past year and a half, black hole scientists around the world have actually been proposing specifications for the future instrument, Wong stated.
