A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. This makes them invisible to the naked eye and difficult to study. Black holes are formed when massive stars collapse under their own gravity at the end of their life cycle. They are thought to play a key role in the evolution of galaxies and the universe as a whole.

Definition:
A black hole is a region of spacetime where gravity is so strong that nothing, not even light, can escape. This happens when the gravitational pull becomes so intense that it creates a singularity where the laws of physics, as we know them, break down.
Characteristics:
- Event Horizon: The boundary around a black hole beyond which nothing can escape, representing the point of no return. Anything that crosses the event horizon will inevitably be pulled into the singularity.
- Singularity: The core of a black hole, where the mass is compressed into an infinitely small point, resulting in infinite density and curvature.
- Gravitational Pull: Black holes have immense gravitational force due to their high mass, influencing the surrounding spacetime and bending the path of light.
- Blackness: Black holes appear black because no light can escape them, making them invisible to telescopes.
Types:
There are two main types of black holes:
- Stellar Black Holes: Formed from the collapse of massive stars at the end of their life cycles.
- Supermassive Black Holes: Found at the centers of most galaxies, containing millions to billions of times the mass of our Sun.
Formation:
- Stellar Black Holes: When a massive star runs out of nuclear fuel, it collapses under its own gravity, creating a supernova explosion. If the remaining mass is above a certain threshold (around 3-5 solar masses), it forms a black hole.
- Supermassive Black Holes: Their formation mechanism is still debated, but theories include the collapse of giant gas clouds in the early universe or the merger of smaller black holes.
Role in the Universe:
Black holes play a significant role in the evolution of galaxies by influencing star formation, regulating gas flows, and potentially merging with other black holes. Their presence also provides insights into the fundamental nature of gravity and spacetime.
