A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar.
Before diving into their collision, it's worth understanding just how extreme these objects are. A black hole is a region of space where gravity is so strong that nothing, not even light can escape once it crosses the "event horizon." Black holes form when the most massive stars collapse at the end of their lives, creating a point of infinite density surrounded by this inescapable boundary.
