What is a Black Hole?
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. It's formed when an astronomical object collapses under its own gravity. Imagine a star imploding and compressing into an incredibly small space, leading to infinite density: a singularity.
Event Horizon
The event horizon is the 'point of no return'. Once crossed, escape is impossible. For this reason, black holes can only be detected by observing their effect on surrounding matter.
Types of Black Holes
- Stellar Black Holes: Formed by the gravitational collapse of a star.
- Supermassive Black Holes: Millions or billions of times more massive than the Sun, found at the center of most galaxies.
