write a brief description of the characteristics of a black hole.
user
a black hole is an astronomical object with an extremely strong gravitational pull. it is formed when a star collapses under its own gravity. the gravity is so strong that it bends the fabric of space-time and even light is trapped within its boundaries. with no light escaping, a black hole is essentially invisible to observers and can be detected only by its gravitational effects on nearby objects.
