When two neutron stars spiral into one another and merge to form a black hole—an event recorded in 2017 by gravitational wave detectors and telescopes worldwide—does it immediately become a black hole? Or does it take ...

Binary black hole mergers are fascinating cosmological events, which have been theorized to be the among the strongest sources of gravitational waves in the universe. While astrophysicists have carried out extensive research ...
Over the past 6 years, gravitational wave observatories have been detecting black hole mergers, verifying a major prediction of Albert Einstein's theory of gravity. But there is a problem—many of these black holes are unexpectedly ...
