| biography:
| Theoretical astrophysicist, born in Frankfurt, WC Germany. He computed exact solutions of Einstein's field equations in general relativity - work which led directly to modern research on black holes. The Schwarzschild radius is the critical radius at which an object becomes a black hole if collapsed or compressed indefinitely. At this radius the escape velocity is the speed of light. Its value is 9 mm/0·35 in for Earth, 3 km/1·9 mi for the Sun. |
