Have you heard of black holes but are you aware of it?

You may have heard of black holes before. But are you aware of these facts?

What is the horizon of these events? Event Horizon is simply the boundary that represents the boundaries of a black hole. Normally, at this limit, the velocity velocity is equal to the velocity of light. The velocity velocity is the minimum velocity that an object must give to escape from the gravitational pull of another mass object.

According to general relativity, an object cannot travel faster than the speed of light, and for this reason nothing in the Event Horizon can cross the line here. Because of this, anything that enters a black hole will not come out again and we will not be able to see them from outside this boundary. Therefore, no radiation usually emitted or produced within this range is emitted through it.

Considering a non-rotating black hole, its Schwarzschild radius keeps this boundary spherical. Considering a rotating black hole, these events extend across the horizon in an irregular shape. In fact, we cannot say that this limit is a material surface. This is just something with a mathematical definition. Therefore, matter and radiation constantly enter the black hole. A black hole cannot produce radiant energy. Radiation energy and matter exit outside this limit as Hawking’s modification.

What is the Schwarzschild radius?


This radius is usually called the gravitational radius, which is the radius at which the velocity of decay is equal to the velocity of light in a black hole.

When the object falls to a value less than this radius, the gravitational pull between the particles increases, causing the object to undergo an unavoidable level of gravitational collapse. That is when the end times of most stars begin.

The Schwarzschild radius (Rg) of an object of mass M is given by the following formula, where G is the universal gravitational constant and c is the velocity of light.

(Rg = 2GM / c2) For a mass as small as a human, the Schwarzschild radius is much smaller than the nucleus of an atom. For an average star like the Sun, it is about 3 km (2 miles).

What is this Hawking variant? Hawking radiation theoretically emits events outside the horizon in a black hole. In 1974, Stephen W. suggested that one pair of subatomic particles (photons, neutrinos, and some massive particles) that naturally occur near the event horizon could escape from near the black hole (theoretically into the surrounding environment) and the other part could disappear with negative energy. Hawking revealed.

Particles of negative energy then flow into the black hole, gradually reducing its mass. The reduction of that mass eventually results in the complete disappearance of radiation.

Hawking radiation reduces the mass and rotational energy of black holes and is therefore also known as black hole evaporation.
