A Gravity attractiveness Provided Black hole It is so stronger that nothing can escape from him. Even light. So think go to a black hole This is pure science fiction. In fact, so far we have seen it only in films such as famous InterstellarChristopher Nolan. In this tape, life on Earth begins to be unstable, so the astronauts team is forced to explore new worlds next to a supermassive black hole called Gargantóa. The current spaceship could not cope with the attraction prepared by Gargantóa. Use it much less as a driver to visit new worlds. However, according to the astronomer Cosimo BambiIn the future, we could achieve the necessary technology, so it is important to start with preparation.
According to the Italian cosmologist, who is currently trained in University of Fudan, In China, the first step to move to a black hole would be Find much closer than any of the known todayThe field is the closest black hole that we were able to detect is 1565 Light yearsThe field to achieve its achievement of 1565 years will need the speed of light. With a speed achieved by human technology, even more. Therefore, it is impossible to get there. It would be necessary to find a black hole much closer to the ground. Ideally, according to Bambi, it will be about 20 easy years. In this case, a trip can be undertaken, which will be Long, but viable.
This is the step that we must start. As soon as the destination is chosen, this scientist believes that The necessary technologies can be obtained To travel to a black hole. But what exactly will it be? Let’s look at them, but not earlier than understanding why it would be so interesting. There are many advantages on this trip, even in addition to finding the survival of the planet that we saw in Interstellar.
What will help go to a black hole?
Precisely because the light cannot avoid the attraction of a black hole, these supermassive objects Invisibels on our eyes. We cannot see a black hole, but it discovers it according to the radiation emitted by the question that heats up around it. In short, we do not see a black hole, but You can find how this affects the environment.
It even allowed it Bring photos from two black holesThe field but even in this case we still know its structure in the depths. To have clear information, we must go to a straight black hole. In addition, proximity to its environment will help confirm or refute The theory of general relativity Experimentally, not based exclusively on theoretical calculations. The detection of gravitational waves served to confirm the part of what Einstein predicted, but more information is needed.
Both are the reasons that, according to Bambi, will justify the journey to the black hole.
It would be like a trip Interstellar?
What is described in interstellar is theoretically viable. Christopher Nolan developed a film with the Council of Physicist Kip Thorne, who took care that everything was theoretically viable. Now something theoretically viable does not mean that this can be done safely.
Therefore, Bambi developed his own plan to go to a black hole. Firstly, as we have already advanced, the destination should be selected. Although today no one has been discovered close enough, the astronomer believes that the improvements that are carried out during the analysis of gravitational fields will allow you to detect more black holes very soon. Detection will be carried out Analysis of gravitational deformations in space-time.
As soon as the technique was cleaned, it is true that no one guarantees us that this desired next to a black hole can be found. Therefore, we must Raise a few scenariosThe ideal will be a black hole located in 20-25 light years. If it is 40-50 light years, it will be viable, although much more complicated. Further it would be impossible.
After the destination was selected, it is necessary to choose the right ship. Those that are currently used are too slow. However, in 2016, a project to develop Space Nanonavians This can collect the necessary qualities. Myself Stephen Hawkings He was among the thinking leaders of this project.
Nanonavians used to move to a black hole would be very small ships, from nanometric sizes, First feeds on lasers directed from the ground, and then, when they approached their fate through Solar energy Or any other star. Thus, without ordinary chemical fuel, speed A third of the world. You can reach a black hole after about 70 years. This is a lot, but much more vitality than thousands of years that will be required to achieve the nearest black hole, which is currently known.
And what would they have done then there?
Bambi believes they need at least two probes To rotate a black hole. One of them will approach the black hole as much as possible, and there, It will be divided into the main probe and many smaller probesThe latter can communicate with each other by sending electromagnetic signals that will help to know the structure of the black hole much better, since its only presence will lead to many vibrations in these signals.
All these measurements will be sent back to Earth, at the speed of light. Therefore, they will take At best about 20 yearsField if we add everything, the mission is coming Almost a centuryThe field of several generations of astronomers should have controlled the project, but for this scientists it is still worth it.
When are we starting?
At present, we do not have a technology for creating the necessary nanonabs, and, in addition, only lasers for their management will cost About one billion euros. It is impossible to get to work. Nevertheless, Bambi believes that in 30 years technology could develop, and costs could be enough to start preparing for the trip. There are many more, but knowing that he considers him viable, it would be nice to think about how to look for this nearby black hole. Will it be as simple as he pint?
