The Schwarzschild radius, or event horizon, of a black hole is the distance from a black hole at which the escape velocity is the speed of light. Calculate the Schwarzschild radius of a black hole with the mass of Mount Rushmore (reminder: Mt. Rushmore has a mass of about 3 x 1013 grams).

The gravity of a black hole is so strong that not even light can escape from within its surface or “event horizon.” Even outside that surface, enormous energies are needed to escape. Suppose that you are 11.0 km away from the center of a black hole that has a mass of 1.00x1031 kg. If your mass is 72.0 kg, how much do you weigh? NOTE: The answer im getting is 3.968*10^14 N. However, it is not accepting the (*10^14 on...

(3.) The first realization that supermassive black holes existed came from observational inference of the luminosity of QSOs and Active Galactic Nuclei. The Eddington Luminosity is the maximum rate at which an object of can radiate photon energy before the momentum transfer from the photons moving through the material in the object tear it apart (a.)

A black hole is an object with mass, but no spatial extent. It truly is a particle. A black hole may form from a dead star. Such a black hole has a mass several times the mass of the Sun. Imagine a black hole whose mass is fifty-seven times the mass of the Sun. Would you expect the period of an object orbiting the black hole with a semimajor axis of 1 AU to have a period greater than, less...

Black hole of Schwarzschild.
The Schwarzschild solution is an exact solution of Einstein's
equations in the vacuum that is static and spherically
symmetric.
The interval is given by: (1)
(a) they are conserved quantities: (2)
Due to an additional symmetry, the movement is confined to a plane,
which can be chosen as the equatorial plane, θ = π / 2. Write (1)
in terms of,A (r), (dr / dτ) 2 and dτ.
(b) Show that (3) is constant throughout
geodesics....

Black holes have a special boundary called the event horizon, beyond which not even something traveling at the speed of light can escape. Use what you know about escape velocity to find the event horizon distance for a 5 solar mass (1 Msolar = 2x1030 kg) black hole. Your answer will be in meters.

I want to know whether mass of the black hole which has born from a star is similar to its parent star or not. whether the born black hole will have high or low mass comparing to its parent star. Whether in its life time black hole will increase mass by eating neighboring stars? Advance thanks for your help
