An object is accelerated close to c. Does the relativistic mass contribute to the sch. radius as seen by an observer? Is it simultaneously a black hole and not a black hole?
The Schwarzschild radius, also known as the gravitational radius, is a measure of the size of the event horizon of a black hole. It represents the distance from the center of the black hole at which the escape velocity equals the speed of light.
The Schwarzschild radius can be calculated using the formula Rs = 2GM/c^2, where Rs is the Schwarzschild radius, G is the gravitational constant, M is the mass of the black hole, and c is the speed of light.
Yes, any object with a mass can have a Schwarzschild radius, but it is only significant for objects with extreme densities, such as black holes.
At the Schwarzschild radius, the escape velocity is equal to the speed of light, which means that anything that crosses this boundary will be unable to escape the gravitational pull of the black hole.
Yes, the Schwarzschild radius can change if the mass of the black hole changes. As the mass increases, the Schwarzschild radius also increases, and vice versa.
