Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet Earth rolls around the sun ...

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 ...
