Study Notes
Black Holes and Light
- A black hole's gravity is so strong that it warps the fabric of spacetime, bending and trapping light around it.
Boundaries of a Black Hole
- The boundary of no escape in a black hole is called the event horizon.
Hawking Radiation
- Stellar black holes emit Hawking radiation, which has a temperature of around 10-8 Kelvin.
- Hawking radiation is a theoretical prediction in quantum mechanics that black holes emit radiation due to quantum effects.
