The 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 were to be compressed within that sphere, the escape velocity from the surface of the sphere would equal the speed of light. An example of an object where the mass is within its Schwarzschild radius is a black hole. Once a stellar remnant collapses to or below this radius, light cannot escape and the object is no longer directly visible, thereby forming a black hole. It is a characteristic radius associated with every quantity of mass. The Schwarzschild radius was named after the German astronomer Karl Schwarzschild, who calculated this exact solution for the theory of general relativity in 1916.
Usage examples of "schwarzschild radius".
Globalism and tribalism have run to completion, diverging respectively into homogeneous interoperability and the Schwarzschild radius of insularity.
Of course, even for the heaviest elementary particles the Schwarzschild radius is far smaller than the Planck-Wheeler length, so quantum uncertainty would disrupt any potential event horizons, and perhaps even smooth away the singularity as well.
The black hole was set into a netlike structure that started just outside the Schwarzschild radius and extended kilometers.
If the Sun were to become a black hole, as mentioned earlier, its Schwarzschild radius would be about three kilometers and its mean density twenty billion tons per cubic centimeter.
His solution behaved very strangely at a critical distance from the centre of the sphere, now called the Schwarzschild radius.
Thus by our clocks it will take infinite time to shrink to the Schwarzschild radius.
That tiny explosion had not been visible but a second later the expanding Schwarzschild radius is eating its shell, swallowing thirty-six thousand tons of fragile dodecahedron, and growing quickly to gobble several thousand kilometers of space around it.
And he wondered now, with the ferry's rocket engine hurling itself against the vehicle's frail frame, using that frame to hold back the enormous mass of the Possum, whether he hadn't already slipped inside a Schwarzschild radius.
Meanwhile, the Schwarzschild radius of their immense black hole kept out something they feared even more.
