How a black hole is formed

how a black hole is formed

One of the most feared elements in the universe is the black hole. It is estimated that the center of our galaxy is formed by a super massive black hole. It is about a point, gravity is practically infinite and it is trying to "swallow" everything in its path. Science has studied how a black hole is formed and what are the chances that they are getting bigger and bigger.

Therefore, we are going to dedicate this article to tell you how a black hole is formed and what its characteristics are.

key features

inside a black hole

These black holes are nothing more than the remains of ancient stars that no longer exist. Stars tend to have a lot of matter and particles, so they have a lot of gravity. You just need to see how the sun has 8 planets and other stars continuously surrounding it. The solar system exists due to the gravity of the sun. The earth is attracted to it, but this does not mean that we are getting closer and closer to the sun.

Many stars end their lives in the form of white dwarfs or neutron stars. Black holes are the final stage in the evolution of these stars much larger than the sun. Although people think that the sun is large, it is still a medium star (even small when compared to other stars). That is why there are stars 10 and 15 times the size of the sun, and when they cease to exist, they will form a black hole.

If no force can stop the action of gravity, a black hole will appear, which can shrink all of space and compress it until its volume is zero. At this point, the density can be said to be infinite. In other words, the amount of matter that can be in zero volume is unlimited. Therefore, the gravitational force of that black spot is also infinite. Nothing can escape this attraction.

In this case, even the light that the star possesses cannot escape gravity and is trapped in its own orbit. For this reason, it is called a black hole, because in this volume of infinite density and gravity, not even light can emit light. Although gravity is infinite only at the point of zero volume where space folds, these black holes attract matter and energy to each other.

how a black hole forms in space

Black holes are made up of only very massive stars. When they run out of fuel at the end of their lives, they collapse in a catastrophic and unstoppable way, and when they collapse, they form a well in space - a black hole. If they are not that large, the material that makes them can prevent them from collapsing and forming a dying star that barely emits light: a white dwarf or a neutron star.

The difference between black holes is their size. Stars are those that have a mass equivalent to that of the sun and a radius of tens or hundreds of kilometers. Those with masses reaching millions or even billions of times the mass of the sun are supermassive black holes at the core of galaxies.

There can also be intermediate black holes, hundreds of thousands of solar masses, and early black holes formed at the beginning of the universe, and their masses can be very small. Their gravitational pull is so great that they can't just escape its attraction. If the fastest light in our universe cannot be turned off, then nothing can be turned off.

galaxies and stars

Although it has always been thought that a black hole will attract everything around it and engulf it, this is not the case. For the planet, light and other matter to be swallowed up by the black hole, you must be too close to him to be attracted to his center of activity. Once you reach the point of no return, you enter the event horizon, where you cannot escape.

And once we enter the event horizon, we can move, we must be able to move faster than light. The size of the black hole is very small. A black hole, such as those found at the centers of some galaxies, it has a radius of up to 3 million kilometers. There are more or less about 4 suns like ours. If a black hole has the same mass as our sun, then its diameter is only 3 kilometers. As always, these spaces can be scary, but everything in the universe is.

It must be emphasized that a black hole can trap all matter and space-time itself in it. Not only can it catch light, but it is a center with such a center of gravity that it can intensify everything we say. The hole itself is completely black and has no features. Until now, they were unable to return home due to the great impact they had on their environment. They are also known for the tremendous energy they release.

That is why the first exposure to a black hole is due to the use of a network of mirrors. These radioscopes can measure radiation from space. It does not point us to the universe like a telescope. To specifically detect two black holes, a fluoroscope has been used. One of them is the supermassive black hole at the center of our galaxy.

Evolution of a black hole

Because they are small and dark, we cannot observe them directly. Because of this, scientists have long suspected its existence. Something that is known to exist but cannot be seen directly. To see a black hole you must measure the mass of a region of space and look for regions with a large amount of dark mass.

There are many black holes in binary star systems. They attract a lot of mass from the stars around them. When it attracts these qualities, its size increases and it becomes larger. One day, the companion star from which the mass derives will disappear completely.

As you can see, one of the most studied things in the universe is how a black hole forms. I hope that with this information you can learn more about how a black hole is formed and what its characteristics are.
