Black holes are absolutely fascinating! They are these incredibly dense objects in space that have such strong gravitational forces that nothing, not even light, can escape their pull. They form when massive stars collapse under their own gravity, creating a point of infinite density called a singularity. The concept of black holes challenges our understanding of physics and raises questions about the nature of space and time. They are like cosmic mysteries waiting to be unraveled, and studying them helps us gain insights into the fundamental workings of the universe.
