Study Notes
Black Holes
- A black hole is a region of spacetime with an extremely strong gravitational pull.
- The gravity is so strong that nothing, including light and other electromagnetic waves, can escape once it gets too close.
- According to Einstein's theory of general relativity, a compact mass can warp spacetime to create a black hole.
- The mass must be sufficiently compact to form a black hole.
