What Is A Black Hole?
A black hole is a region of space where the gravitational force is so strong that nothing, not even light, can escape from it. Black holes are formed when massive stars collapse in on themselves under the force of their own gravity.
The gravity of a black hole is so intense that it warps the fabric of space and time around it, creating a region known as the event horizon. The event horizon is the point of no return, beyond which anything that enters the black hole is unable to escape. Once something crosses the event horizon, it is effectively lost from the observable universe.
Black holes come in different sizes, from small ones that are just a few times the mass of the Sun to supermassive ones that contain billions of times the mass of the Sun. Supermassive black holes are thought to be present at the centers of most galaxies, including our own Milky Way.
Black holes are important objects for astrophysics and cosmology because they provide insights into the nature of gravity, the behavior of matter and energy in extreme conditions, and the evolution of galaxies over time.
