...it would take a very special magnetar to unleash such monstrous FRBs in quick succession. “A neutron star bursting at this rate for thousands of years would quickly run out of fuel,” he said. His best guess is that the repeater is a very young magnetar — probably less than 100 years old. Yes, billions of years ago, there was a thing that lasted possibly one hundred years, but in that time during its existence it emitted radio bursts, and we're only noticing them right now.
