Black Holes Explained: From Theory to Discovery

What is a Black Hole?

A black hole is a region of spacetime where gravity is so strong that nothing - not even light - can escape once it crosses the event horizon.

Types of Black Holes

• Stellar - Formed from collapsing massive stars.
• Supermassive - Found at galactic centres; millions to billions of solar masses.

The Event Horizon Telescope

In 2019, scientists released the first-ever image of a black hole - M87*, 6.5 billion solar masses, 55 million light-years away.
