Event horizon

black hole

When talking about the first photograph of a black hole made, a term known as event horizon. It is the last shadow before a deep black that is able to swallow all the light so as not to let it come out again. Many people wonder what this means.

Therefore, we are going to dedicate this article to tell you all the characteristics, origin and importance of the event horizon.

What is the event horizon

It must be emphasized well that black holes are capable of trapping all matter and space-time itself inside. Not only can it catch light, but it is a center with such gravity that it can aggravate everything we have mentioned. The holes in themselves they are completely black and devoid of any features. Until now they have only been able to not be home due to the immense effects they cause around them. They have also been known for the enormous energy they give off.

This is the reason why the first time that a black hole has been contacted has been thanks to the use of the radioscope network. These radioscopes can measure radiation from space. It does not point us to the universe as a telescope would. To specifically detect two black holes, fluoroscopes have been used. One of them is the supermassive black hole at the center of our galaxy. The other are the core of the galaxy M87.

Thanks to current computer programs, we can translate the data provided by radio telescopes into images. It is because of this that the first photograph of a black hole was made.

Point of no return

Keep in mind that you can't see anything in a black hole. We can only see the trace of the energy released by the gas that rotates in its environment. Said gas it is super hot and emits a lot of radiation. Radiation can pass through the dust clouds around all black holes. The shadow that can be seen gives us some information about how space-time bends in the immediate environment of the black hole.

Right after all this part is the event horizon. It should be noted again that you cannot expect to see any lights or fringes that can be pointed out. And it is that this event horizon is an imaginary border. If we could cross the event horizon we would not notice any type of change. This is because it is not a natural surface, but the point of no return of the hole. This point means that, from there, there is only one possibility: that we continue to fall into the hole without the possibility of turning back.

The great force of gravity that black holes have attracts everything that is inside them. Such is the amount of mass and density that it has that they exert an enormous pressure.

Theoretical explanation of the event horizon

We are going to give a somewhat more theoretical explanation to try to visualize the characteristics and the essence of the event horizon. Keep in mind that the event horizon of a black hole is linked to the escape velocity of the object. It is about the speed that a hypothetical person will go into the black hole. This speed it would have to overcome the gravitational pull of the black hole. The closer someone gets to the black hole, the greater the speed they would need to be able to escape the massive force of gravity.

The event horizon can be said to be the threshold around the black hole where the escape velocity exceeds the speed of light. Until today we have not found anything that has a speed greater than the speed of light. This is seen in the special theory of relativity of Einstein. Since in theory there is nothing that can travel at a higher speed, it means that the event horizon of a black hole is essentially the point where nothing and no one can return. The name refers to the impossibility of witnessing any event that takes place within that border, the horizon beyond which one cannot see.

Let us assume that there is a hypothetical traveler that exceeds the event horizon. From here, the theory states that the entire mass of the object it has collapsed into an infinitely dense expanse. This means that the fabric of space and time as we know it has been completely warped. And it is that it has been curved to an infinite degree. Inside this black hole, past the event horizon, the laws of physics that we know according to Einstein's theory do not exist.

full discovery

Scientists have been able to photograph something that was not thought could and does not exist. Until recently, black holes were thought to be nothing more than theoretical that served to explain certain patterns in the universe. However, thanks to current technology, we can have the first photograph of a black hole.

It is a fact that for the world of science it has meant a great advance. Keep in mind that many textbooks related to the universe will have to be rewritten. The large amount of information that we currently have with respect to the past, means that we have to be constantly updated.

The black hole in our galaxy is known to be capable of absorbing whatever lies ahead. Not even light can return from the event horizon. Absolutely everything that crosses in this The horizon ends up deforming as it happens with space-time. It is curious that there is a place in the known universe where the laws of physics as we know it cannot be applied, since they do not exist.

I hope that with this information you can learn more about the event horizon and its characteristics.
