A black hole is a region of space where the gravitational pull is so strong that nothing, not even light, can escape from it. The boundary around a black hole is called the event horizon. Once anything crosses this boundary, it is irrevocably drawn into the black hole.
Black holes form from the remnants of massive stars that have ended their life cycles. When such a star runs out of nuclear fuel, it can no longer counteract the force of gravity with the pressure from nuclear fusion. This causes the core to collapse under its own gravity, potentially forming a black hole if the mass is sufficient.
The different types of black holes are:
1. Stellar black holes: Formed from the collapse of massive stars.
2. Supermassive black holes: Found at the centers of galaxies, including our own Milky Way, and have masses millions to billions of times that of the Sun.
3. Intermediate black holes: With masses between stellar and supermassive black holes, they are a bit more mysterious and less understood.
4. Primordial black holes: Hypothetical black holes that may have formed soon after the Big Bang.
Black holes are studied through their interaction with nearby matter and the radiation emitted from accreting materials, such as in accretion disks or relativistic jets.
