Just look at the sky on a clear night and is radiant in a black dress studded with stars that add elegance and splendor. It is the adornment of the sky in which poets and writers have sung since the dawn of history. Despite her beauty that enchants every eye that sees her, her final fate is frightening to the point of horror.


At the end of their lives, the stars turn into something that swallows everything. The laws of physics cannot describe their condition. It can be referred to as the point of no return or the terrifying unknown. They are black holes.

In April 2019, scientists were able to take the first picture of the black hole, which made it a reality with conclusive evidence after many scientists questioned it, led by the creator of the general theory of relativity, which proved the idea of ​​​​the existence of cosmic bodies that devour everything that passes around it, it is the late physicist Albert Einstein.

And he is the same who stated in one of his research papers in 1939, that the idea of ​​black holes is not convincing and that such a phenomenon does not exist in reality. But despite being Einstein, scientists did not give in to him, and they searched behind the idea, most notably Stephen Hawking.

Many people are wondering about the fate of astronauts who might run into black holes and be devoured by them. In this regard, many scholars have endeavored to search for an explanation for this situation. This is what we will discuss in our report now. Before that, let’s learn some information about black holes.

At the beginning of the story ..the universe from the perspective of Newton and Einstein, and between them there is a third

At the beginning of the story

It is said that while Newton was sitting under an apple tree, an apple fell to the ground. And because Newton is a deep man, he did not pick it up to eat it, but wondered, Why did this apple fall and not rise? Hence the idea of ​​gravity, which included the universe.
The prevailing interpretation of the question “Why does the Moon revolve around the Earth?” The Earth’s gravity is stronger than the Moon’s, so the Moon is attracted to it. And almost the same answer when asked why the earth revolves around the sun? Because the gravity of the sun is stronger than the earth, and so on.

In 1783, there was an English Christian clergyman named “John Michael”. Michel loved astronomy and studied various theories of the universe. Based on Newton’s theory of gravitation, he proposed the existence of invisible objects that could attract stars and other objects.

What is more, he pointed out a very important piece of information, which is that we can infer these attractive objects if a star happens to be orbiting around them. (Hat a moment for this guy.)

Do you realize what this genius means, who may have only had a primitive telescope that helped him spot only celestial bodies close to Earth! The idea of ​​spotting the first truly black hole in the 1970s was based on the presence of a star near something unseen by the Royal Observatory in Greenwich. This star was 6000 light-years away!

Well, let’s go back in time a bit before the black hole was spotted. At the beginning of the 20th century, the brilliant physicist Einstein launched his famous theory of general relativity, which introduced new concepts about gravity.

The theory of general relativity assumes that the universe has four dimensions: length, width, height, and time. The last dimension was unfamiliar, and this is where Einstein’s genius stands out. He also assumed that the universe is a fabric of space-time, to simplify the idea.

“Matter tells space-time how to bend, space-time tells matter how to move.”

John Wheeler (The first person to coin the term black hole)

Get a fairly long piece of paper or cloth and have two people hold the ends of the piece or tie them together using the easel. Then put a ball in the middle..what will you notice?

Well, you will find that the cloth is deformed in the area where the ball rests. Next, get a smaller ball and leave it on the fabric.

You will notice that it is moving towards the larger ball. This is exactly what is happening at the level of the universe.

The universe is a fabric of space-time (a piece of cloth) and large bodies such as the sun (the big ball) distort this cosmic fabric, and small bodies such as the Earth (the small ball) move towards it, which explains the presence of planets around the sun. The same is true for other planets and moons. This is spacetime in a nutshell.

Karl Schwarzschild .. The man who led general relativity to the singularity point

Karl Schwarzschild

In 1916, a physicist who used Einstein’s theory and hypothesized the existence of a so-called “singularity”, this scientist is “Karl Schwarzschild”.

A singularity refers to a region so small, infinitely high in density, that its gravity is infinite, so much so that no light can escape from it. It is called the point of no return, and because of it, a distortion occurs in space-time. This point is surrounded by a region known as the “event horizon”.

The event horizon.. where the laws of physics as we know it collapse

The famous physicist Kip Thorne said that singularity is the region where the laws of physics break down. It is located just beyond the event horizon. After passing the event horizon, the physics as we know it disintegrates, no one knows what could happen, but no information can certainly escape from it.

Einstein remained unconvinced by this idea of the singularity, which is rare, despite the support of mathematics, but the scientific possibility was slim from his point of view, at the same time he was preoccupied with the connection between his theory of general relativity and quantum mechanics.


Einstein cannot be blamed for not being convinced, he had his reasons, as it turned out later that this singularity point could not be monitored, and it could only be observed during the Big Bang when the singularity point was naked and clear. But fate had something in store for it.

The bleak fate of the giant star.. about the black hole

In 1935, Indian physicist Subrahmanyan Chandrasekhar linked what would happen when a star reached the end of its life and the singularity point.

He suggested that the giant star begins to run out of fuel as it approaches the end of its life until it runs out completely, and the pressure increases at a specific point, in which infinite gravity is concentrated, and the star collapses into a tiny point, infinitely heavy, that even causes a distortion in the fabric of space-time.

It is the singularity point. With this work, Chandrasekhar bridged the gap between mathematical calculations and scientific probabilities, which later helped scientists.

In 1958, David Finkelstein, an American physicist, concluded that nothing can escape the singularity, based on mathematical equations. In the 1960s, Stephen Hawking and Roger Penrose demonstrated the existence of the singularity, and that it is part of the star’s cycle that cannot be ignored. About 12 years after the death of Einstein (1955), “John Wheeler” launched the term black hole at a conference in New York in 1967.

A question that intrigues me: What would happen if I fell into a black hole?

The short answer to this question is: “Nobody knows!” You might think I’m making fun of you, and I’m telling you, it’s unknown! But do not oppress me, there is interesting information that I would like to share with you, and it is all the jurisprudence of great scientists, including the late Stephen Hawking, the star of the scientific arena in his time, and scientists are still guided by the light of his knowledge to explore the universe. Drawing on Einstein’s general theory of relativity, scientists have struggled to explain what would happen if a person approached a black hole.

What happens if you fall into a black hole?

Assuming you get close to a black hole, do you know the effect of tides? Yes, just as the moon does with the earth, the side facing the moon is attracted to it, making it an oval. This effect occurs when a person or an object approaches the black hole, feels more gravity at the top of the head than the rest of his body and the tips of his feet, and the body expands and becomes longer and longer, the atoms of the body disintegrate, this is called the “noodle effect”, where gravity is pressing on the body horizontally, You pull it vertically, and your body ends up being a stream of disintegrating subatomic particles moving into the black hole. But you will not be able to perceive all this, because the atoms in the brain disintegrate quickly, and therefore you do not witness what the black hole is doing in your body.

As for the slowdown. If we assume that we are observing a person in the vicinity of a black hole, we are standing at a safe distance, while he approaches and approaches until he reaches the event horizon, the region of no return. We will never be able to save him, our human capabilities can’t stand this cosmic force, all we will do is document this event and watch what happens to it. However, we will notice something more like a fantasy, this person will slow down until he appears to be still. It is over, as time slows down there from the excessive speed with which the body is attracted and fragmented inside the black hole, while time passes naturally for us, in other words, time stops completely there at the event horizon. The matter of this poor man who fell a long time ago is over.

To make it simpler, do you know the maximum recognized speed? It is the speed of light, which is estimated at 299792458 meters/sec. Can you imagine that the light that moves at this tremendous speed cannot escape the influence of the gravity of the black hole? This means that the human body, or even spacecraft, cannot escape and survive this enormous gravity, and when a person approaches it, it pulls it at a speed approaching the speed of light, and the faster the body moves in space, the slower its movement through time, which explains why there is a slowdown In time, a person appears to be standing still, when his life is already over! This leads us to another question that is closer to the imagination.

What will a person who has fallen into a black hole see if he is still alive? This is an imaginary question, and its answer is only assumptions, but for sure, no one survives the inevitable fate when approaching a black hole, but suppose you survived, what will happen? You will witness that everything inside the event horizon will be distorted and torn by gravity, this is called “gravitational lens”, however, it is impossible to witness these events, as the human body will be torn quickly and its inevitable fate is death of life.

Conclusion :

Finally, everything that happened reflects the experiment of space-time curvature predicted by Einstein’s general theory of relativity. The end may seem a little tragic, but do not worry, my friend, the closest black hole that scientists have identified is 1000 light-years away from us, and there is no need to worry.
