Try John Walker's Orbit's in Strongly Curved Spacetime for a Java applet which allows you to play around with orbits in the Schwarzschild geometry. Schwarzschild radius One of the remarkable predictions of Schwarzschild's geometry was that if a mass M were compressed inside a critical radius r s , nowadays called the Schwarzschild radius, then its gravity would become so strong that not even light could escape. The Schwarzschild radius r s of a mass M is given by r s where G is Newton's gravitational constant , and c is the speed of light . For a 30 solar mass object, like the black hole in the fictional star system here, the Schwarzschild radius is about 100 kilometers. Curiously, the Schwarzschild radius had already been derived (with the correct result, but an incorrect theory) by John Michell in 1783 (this reference is from Erk's Relativity Pages ) in the context of Newtonian gravity and the corpuscular theory of light. Michel derived the critical radius by setting the gravitational escape velocity

WORM HOLES Worm Holes are the hypothetical theoretical connection between a black hole and a white hole. Specifically defined, a black hole is a region in space where the velocity of escape exceeds the speed of light in that medium. When a star dies and begins to shrink a name is given to the size below which it must shrink in order to become a black hole. The name for this size is the star's "Schwarzchild Radius" and the primary factor which determines whether or not a star will shrink below it's Schwarzchild Radius is its initial mass. Schwarzschild Radius also called gravitational radius, distance that defines the size at which a spherical astronomical object such as a star becomes a black hole. A black hole is an object so dense that not even light can escape the pull of its gravitational force. If an object collapses to within its Schwarzschild radius, it becomes a black hole. The radius is named after German astronomer Karl Schwarzschild, who derived the first model of a black hole in 1916. Nothing, not even a particle moving at the speed of light, can escape the gravitational pull of a black hole. Therefore, the Schwarzschild radius is the largest radius that a body with a specific mass can have and still keep light from escaping. The formula for the Schwarzschild radius of a body is the Schwarzschild radius of the body, G is a constant known as the universal constant of gravitation, M is the mass of the object, and c is the speed of light.

Forward Back Up Map ... Information The Building Blocks of Code Numerical Relativity Timeline One doesn't learn to play the piano by first tackling Beethoven's sonatas. Neither do numerical relativists attempt to solve Einstein's equations describing the most complex model: two asymmetric spinning black holes rotating around and spiraling toward each other until they collide. Numerical relativists have cut their teeth on a comparatively simple, spherical model: the Schwarzschild black hole. Although Karl Schwarzschild analytically solved Einstein's equations for a spherically symmetric, stationary black hole in 1917, his solution demanded a very special choice of space and time coordinates. In computer simulations of black holes, these special "Schwarzschild" coordinates are not practical, even for purely spherical black holes. In other coordinate systems, even this spherical black hole will appear to be extremely dynamic and is quite difficult to study numerically. It wasn't until 1987, however, that numerical relativity researchers were able to employ then powerful supercomputers such as the CRAY X-MP and more accurate algorithms to solve the equations for the more general spacetimes of dynamic systems, such as colliding or spiralling black holes.

Astro-Fact: Karl Schwarzschild by Carmen Rush Like Father, Like Son Karl Schwarzschild (1873-1916) was a German astronomer and the creator of the famous term the Schwarzschild Radius of black holes. He became interested in astronomy as a young boy and at 16 published papers on binary orbits. He became director of the Potsdam Observatory in 1909, where he made great advancments in photographic methods. But his greates contributions were theoretical. In 1916 while serving on the Russian front, Schwarzschild wrote two papers on Einstein's theory of relativity. In them he was able to successfully solve the complex partial differential equations that Einstein had been unable to do. He developed the idea that when a star contracts under gravity, there will come a point that the growing gravitational field of the star will not allow even light to escapehence becoming a black hole. The radius at whitch a star of given mass must contract to reach this stage is his famous Schwarzschild Radius. (For our sun to reach this point it would have to have the radius of 2.5 km!) Obviously Karl's work impressed his son, Martin. Martin also became an astronomer and focussed on the evolution of stars and galaxies. He used balloons to carry telescope to study the sun at elevations of over 24,000 meters. He has also worked on the range of mass shown by starsthat is now thought to be from one-100th of the sun to about 65 solar masses.
