Black Hole

A black hole is an astronomical object with a gravitational pull [blank] powerful that nothing can escape from it, including light. Black holes form [blank] massive stars collapse at the end of their lifecycle. This collapse causes a singularity, a point where density and gravity become infinite. Surrounding the singularity is the event horizon - the boundary past which no matter or information can escape from the intense gravitational effects. Supermassive black holes likely [blank] at the center of most large galaxies. Evidence indicates the giant elliptical galaxy Messier 87 contains a supermassive black hole over 6 billion times the mass of our sun. NASA recently captured the first image of this black hole's event horizon and shadow, providing clues [blank] its formation and behavior. Understanding more about black holes [blank] shed light on galaxies' formations, the fundamental laws of physics, and intricate processes occurring at the edge of a black hole's event horizon still shrouded in mystery.
