🕳️ Black Holes

About Black Holes

A black hole is a region of spacetime where gravity is so strong that nothing — not even light or other electromagnetic waves — has enough energy to escape. They are among the most fascinating and mysterious objects in the universe.

🌟 Key Facts

• Types: Stellar, Intermediate, Supermassive, Primordial
• Formation: Massive star collapse (supernova)
• Event Horizon: Point of no return
• Milky Way Center: Sagittarius A* (4 million solar masses)
• First Image: M87* captured in 2019 by EHT
• Smallest Known: ~3 solar masses
• Largest Known: TON 618 (66 billion solar masses)
