WebThe Schwarzschild radius is defined indirectly by the formula Area of the black hole’s horizon = 4 times pi times (Schwarzschild radius)². It is directly proportional to the black hole’s mass. The Schwarzschild radius for an object the mass of the earth is 9 millimetres, for an object with the mass of the sun, 2.95 kilometres. WebThe *Schwarzschild radius* (sometimes historically referred to as the gravitational radius) is the radius of a sphere such that, if all the mass of an object is compressed within that …

Web23 Sep 2024 · The radius at which a mass has an escape velocity equal to the speed of light is called the Schwarzschild radius. Any object that is smaller than its Schwarzschild radius is a black hole – in other words, … WebThe Schwarzchild radius is named after Karl Schwarzchild (1873 - 1916), a German astronomer who was the first to formulate this concept. When a star becomes a back hole, it has actually become a gravitational singularity surrounded by an event horizon. starcraft 4th race

Web26 Nov 2024 · The largest such radius is called the Schwarzschild radius. As a matter of fact our own Sun would be a black hole if it had a radius of less than 3 km and the same mass, and the Earth would be a black hole if it had a radius of less than 9 mm and the same mass. Share Cite Improve this answer Follow edited Nov 29, 2024 at 10:41 Web11 Apr 2024 · The Schwarzschild radius is given by r s = 2 G M c 2 in SI units and using the given data (we only really need the mass of the black hole which is M = 6.6 × 10 9 × 2 × 10 30 ≈ 13.2 × 10 39 kg where the mass of the sun is approximately 2 × 10 30 kg) it is straightforward to calculate the Schwarzschild radius in SI units WebIf an object exists entirely within its Schwarzschild radius then it is referred to as a black hole. This radius grows with the mass of the object according to the formula: Notice that for our sun we obtain a radius of 2.95 kilometers. This is well within the interior of the sun so it is not a black hole. starcraft 8
