Recently, world science news has been reminiscent of science fiction opuses. The recognized geniuses of this genre, the peak of popularity of which came at the beginning of the 20th century, never dreamed that their grandchildren would already quite seriously talk about resettlement to Mars, deep space exploration, genetic experiments, DNA cloning, and so on. The latest sensation is a successful quantum teleportation over a huge distance - 1.2 thousand kilometers. What does this mean and what prospects does it open up for science?

Quantum teleportation between Earth and space was carried out by the Chinese using a pair of satellites and three ground stations. The corresponding study of scientists was published in the journal Science, briefly reported by the Science and Technology University of China. It is said that the efficiency of information transmission by the new method significantly exceeds the indicators of fiber-optic cables.

In science fiction literature, teleportation is the instantaneous movement of an object from one point in space to another. From a scientific point of view, the same is the transfer of the quantum state of a particle over a distance. For this, a spaced pair of entangled particles is used: according to quantum mechanics, even when they move away from each other, they retain information about the state of their partner (the so-called principle of local realism). From the point of view of a normal person - complete nonsense. But in fact, even quantum physics can be explained “on the fingers”. At one time, when Albert Einstein was asked to formulate the theory of relativity "for dummies", he said: "This is when Zurich stops near this train." If we operate with the same simple categories, then the essence of quantum teleportation is that any object (in particular,the human body) can be sent on a journey, having previously disassembled into very small parts (in this case, atoms) according to the same principle as the designer. And since any material object is a set of these very cohesive particles, and they are attracted to each other through space and time, then at the final stage the body should sort of come together.

However, what is already familiar to us from films and books has not yet been implemented in practice. At the moment, scientists only send individual particles on the journey. Let's face it: the reliability of such experiments for an ordinary person is very, very controversial. As they say, you can't hold a photon in your hands, but we all know how to tell fairy tales.

By the way, about fairy tales. Did you know that “teleportation” as a term and concept was first born not at all in a scientific, but in a literary environment? It is not for nothing that it is believed that there is a very real element of mysticism in fiction. For example, the word “robot” was invented by Karel Čapek at a time when mankind did not even think about robotics. The Englishman Herbert Wells was also the most real visionary. In 1895, ten years before the advent of the theory of relativity, in his Time Machine, he suggested that our reality is four-dimensional. Two years later, in War of the Worlds, he described the work of a laser. Meanwhile, Einstein did not even discover the existence of the phenomenon of stimulated radiation (the physical basis for the operation of any laser), but only predicted only in 1916. In 1914, in the novel “The Unleashed World,” the writer mentions a bomb, the action of which is based on the fission of an atom. And work on the creation of such a weapon begins only in 1939, when the French physicist Joliot Curie discovers a chain reaction of uranium. In 1923 Wells writes about parallel worlds and antigravity. Needless to say, now (after almost a hundred years have passed) these are trending areas of research.

However, H. G. Wells is far from the only person who, without a special education, made a colossal contribution to science. There is an interesting study of Mark Twain by practicing scholars. Outstanding minds, having analyzed all the writer's works, came to the conclusion that out of more than 100 ideas described in his books, only 10 are fundamentally unrealizable. And this statement is controversial, because science is constantly moving forward.

But here's what's interesting: the more scientific thought develops, the more questions scientists face. And all of them, in one way or another, relate to quantum physics - the field of knowledge that studies the behavior of subatomic particles at the smallest distances, where mysterious quantum effects manifest themselves and general relativity ceases to work. The most "burning" topics after the discovery of gravitational waves are dark energy and dark matter. It sounds ominous, but the reality is not so much scary as it is mysterious.

The universe continues to expand faster and faster, despite the fact that the main force acting in it - the force of attraction, or gravity, is opposed to this. With this in mind, astrophysicists have suggested that there is an invisible element that counteracts gravity - dark energy. In the scientific sense, this is a "cosmological constant", an inalienable property of space itself. Based on the observed growth rates of the Universe, scientists have concluded that dark energy must account for at least 70% of the total composition of matter in space. But the paradox is something invisible, intangible and in general it is not clear how to look for it.

With dark matter, about the same story - it seems like it exists, but where it is not clear. It is believed that the dark substance permeates everything and consists of "weakly interacting massive particles." But until now, none of the detectors has been able to detect these particles. Scientists joke: maybe science fiction writers will come up with something sensible, and then science will catch up and justify?

COMPETENTLY

Yuri Kurochkin, Head of the Center for Theoretical Physics of the Institute of Physics of the National Academy of Sciences, Doctor of Physical and Mathematical Sciences, Professor:

- Probably, we can talk about some kind of special flair of creative people. The very term “teleportation” was first used in 1931. It was with this word that the American writer Charles Fort designated the strange disappearances and appearances of the paranormal, which, in his opinion, had something in common. In 1956, the concept of “teleportation” appears in the novel “Tiger! Tiger! science fiction writer Alfred Bester, where it is already described in detail and is a key element of the plot. The first experiments in photon teleportation date back to 2011. And now the news about this does not shock either the public or the representatives of the scientific world.

Many countries are experimenting with quantum teleportation. The most famous (at least those that are regularly reported by the media) are in the USA, Switzerland and Austria. By the way, there is a similar laboratory at the National Academy of Sciences. But you need to understand that at the moment we are talking about the transfer of objects of the microworld to some distance - atoms, photons and quanta. In fact, this is something like the initial stage of research. Before moving in space material things (objects of the macrocosm) and people in particular has not yet reached. In fact, as a person who is engaged in relativistic (classical) physics, I am wary of this topic, since there are many specific and not entirely clear points in it. But as a scientist, I do not rule out the possibility that research will lead to success. A year ago I would have saidthat the prospect of human teleportation seems to me distant for at least a thousand years. But, given the rapidity with which scientific thought has been developing in recent years, it is likely that this epoch-making event will occur in 200 years. And this is a very short time.

CURIOUS

Astrophysical evidence suggests that the space-time continuum can be “flat” rather than curved, which means it continues indefinitely. If so, then our Universe is just one of the elements of the infinitely large Multiverse. According to calculations carried out in 2009 by physicists Andrei Linde and Vitaly Vanchurin, after the Big Bang, ten to the tenth power to the tenth power to the seventh power (in short, a lot) of universes were formed. That is, theoretically parallel worlds exist. But we still cannot find them.
