In the case of a black hole, it is the point where the escape velocity is the same as the speed of light c. The event horizon is the point (or a collection of points) in space that divides two areas that cannot communicate back and forth. In this Schwarzschild radius calculator, we can easily compute where it is located. The event horizon is a very important concept when talking about black holes. Let's see now what is the importance of these points and how this black hole Schwarzschild radius calculator works. However, there is a point of special interest for black holes called the event horizon or Schwarzschild radius (that we understand as the surface of the black hole), which is exactly where this calculator becomes the most useful for calculating the black hole gravity. This is the valid approach to calculating the gravity of a normal object or even the black hole's gravity at a point far away from the surface of the black hole.
In a general situation, you can easily calculate the gravitational acceleration by simply using the gravitational force calculator and setting one of the masses to 1 kg. Another useful quantity to study massive objects is the gravitational field or gravitational acceleration, which is the acceleration that any object would experience due to the presence of other massive objects, in this case, a black hole. A black hole attracts other objects with mass with a force that can be calculated using our gravitational force calculator just like any other object with mass. The separation between the region where we know how things work and the region where we don't is called the event horizon, and in a black hole, it is also known as the Schwarzschild radius.ĭespite all this, a black hole behaves like any other massive object when seen from far away. The gravitational field inside a black hole is so strong that not even light can escape from it (hence the 'black' in black hole).
When this happens, the mass density and gravitational force inside the black hole are so strong the laws of physics as we know them cannot explain what happens there anymore.

Although in reality specific things need to happen to create different kinds of black holes, from really tiny ones to the largest single things in the universe. In contrast to things like planets or stars they have no physical size limit, and can literally grow endlessly. The largest things in the universe are black holes. The Black Hole story continues with our Black Hole merch, spanning the whole range from somewhat bonkers to more serious.
