WebProblem 1 - The formula in red gives the Schwarzschild radius of a black hole, in centimeters, in terms of its mass, in grams. From the equation for the radius in terms of the speed of light, c, and the constant of gravity, G, verify the formula shown in red. Answer: Radius = 2 x (6.67 x 10-8) / ( 3 x 1010)2 M = 1.5 x 10-28 M centimeters The geodesics of the metric (obtained where is extremised) must, in some limit (e.g., toward infinite speed of light), agree with the solutions of Newtonian motion (e.g., obtained by Lagrange equations). (The metric must also limit to Minkowski space when the mass it represents vanishes.) (where is the kinetic energy and is the Potential Energy due to gravity) The con…

WebThe Schwarzschild radius is the distance fro the center at which the escape velocity of the black hole surpasses the speed of light. – Brionius Apr 19, 2015 at 19:41 @Brionius: As far as I remember the physics lecture (I'm engineer, not physicist) this definition is based on non-relativistic calculations. Webwhere R S is the Schwarzschild radius, G is the gravitational constant, M is the mass of the object and c is the speed of light. The following table gives the Schwarzschild radii of some familiar astronomical objects: Object Mass R S: Sun: 2.0 × 10 30 kg : 3.0 × 10 3 m = 3 km : Earth : 6.0 × 10 24 kg : 8.7 × 10-3 m = 8.7 mm : Moon: how do innate cells recognize pathogens

WebThe Schwarzschild Radius Any mass can become a black hole if it collapses down to the Schwarzschild radius - but if a mass is over some critical value between 2 and 3 solar masses and has no fusion process to keep it from collapsing, then gravitational forces alone make the collapse to a black hole inevitable.
