They are some of the universe’s densest objects, with masses ranging from the size of stars to several hundred million stars. Their gravitational fields are so intense that not even light can escape them at a certain point, leaving us hopelessly guessing at how reality manifests itself beyond their event horizons.It’s no…

A team of scientists found a compact object 40,000 light-years from Earth that is either a very massive neutron star or an itsy-bitsy black hole, but they’re not sure which.Remake this Sci-Fi Film with Peter Capaldi!The so-called mass gap object has a mass between 2.09 and 2.71 times that of our Sun. For a neutron star—the collapsed, superdense core of a star—that would be huge, perhaps even the largest yet known. But for a black hole—an even more compact object, so dense that not even light can escape it—it would be…
