- Hawking radiation
Formulas
$$R_s = \frac{2GM}{c^2}$$
Schwarzschild radius defining the event horizon
$$M = \frac{v^2 r}{G}$$
Black hole mass from orbital dynamics
Units
| Kilometer | km |
Interesting Fact
Hawking radiation allows black holes to eventually evaporate, though this takes an extremely long time
Key Scientist
Stephen Hawking
Predicted that black holes emit radiation (Hawking radiation)
Ancient Wisdom
Black holes symbolize void and ultimate mystery in many traditions, representing the unknowable and infinite potential beyond ordinary perception.
