The experiment at the Large Hadron Collider refutes the theory of relativity and opportunities — scientists are seriously discussing the reality of time travel — says Alexey Bondarev in magazine № 40 Correspondent on October 14, 2011

Hollywood stars John Travolta and Nicolas Cage was born to perform a duet. In order to see this, not necessarily to revise the classic thriller Face, directed by John Woo. Enough to listen to modern futurologists. Recently, the two Hollywood actors accused that they travel in time.

Unknown collector exposed on Internet auction site eBay photograph taken in 1860. It shows a man, incredibly similar to Travolta. Owner photos brought solid proof of its authenticity and no trace template.

According to prevailing in physics has been a hundred years of the theory of relativity, Albert Einstein, time travel is impossible

Another collector was more talkative. He put on sale picture of the late XIX century, which depicts a man amazingly similar to Cage. Owner photos jokingly claimed that Cage is an immortal vampire who wakes up every 75 years.

How not to remember in connection with these two cases, the hypothesis of time travel!

The third case of this occurred in the spring of this year when one of the users of the popular video sharing YouTube said in one of the films of Charlie Chaplin woman talking on a cell phone. Movie instantly sold on the internet and has been the subject of considerable debate.

Soon after, a woman with a cell phone found in the film by Akira Kurosawa Seven Samurai.

Futurist, The X-Files fans and fans all sorts of conspiracy theories immediately began to say that time travel is real. Serious scientists do not even bother to engage them in discussion.

Experimental result directly contradicts the theory of relativity, according to which at any point in the reference speed of light is constant and nothing can exceed the

According to prevailing in physics has been a hundred years of the theory of relativity, Albert Einstein, time travel is impossible. More precisely, they are possible, but only for bodies under the action of gravity or monstrous moving faster than the speed of light. But, according to Einstein, to exceed the speed of light is impossible.

Break this vicious circle best minds of modern science could not for 100 years, so the impossibility of time travel has become axiomatic.

However, it is time to rethink Einstein. The experiment, conducted by researchers at the European Organization for Nuclear Research (CERN) in Geneva, together with colleagues from the Italian laboratory San Grasso this summer showed that neutrino particles can be accelerated to a speed that exceeds the speed of light.

According to Ruben Sahakian, professor of physics at University College London, the experimental result directly contradicts the theory of relativity, according to which at any point of reference, the speed of light is constant and nothing can exceed.

"There are a dizzying number of consequences — says Sahakian. — In particular, it opens the possibility of time travel. "

The overthrow of the ideals

Neutrino beam, particles smaller than an atom, almost no mass, was launched via an underground tunnel from the Geneva lab laboratory San Grasso at a distance 723 km. Neutrinos arrived at the destination for a few billionths of a second earlier than it would have been moving at the speed of light. Which means, Einstein was wrong, and the speed of light is not an unattainable limit.

The result of the experiment was a surprise to the authors, says a CERN Ereditato Antonio. Actually, the purpose of the project was to study the properties of neutrinos, fundamental particles, which are the real building blocks of the universe. Question the speed with which they move, for the researchers was secondary.

Neutrinos arrived at the destination for a few billionths of a second earlier than it would have been moving at the speed of light. Which means, Einstein was wrong, and the speed of light is not an unattainable limit.

"If the results are confirmed, our understanding of the physics of change — confirms Sergio Bertolucci, Director for Research CERN. — So we have to be sure that there are no other explanations for this phenomenon. "

But now many scientists are ready to count the results are reliable. "In experimental science there is quantifiable measure of confidence in the results — says Sahakian. — Your measurement to exceed the statistical error is at least five times. In this case the figure is six times. "

Sahakyan also believe that if the truth of the data will be proved, it is our fundamental view of the world changed. And one of the most important consequences will repeal the ban on the theoretical time travel imposed by Einstein about 100 years ago.

Back and forth

In the early 1920s, the famous physicist Arthur Eddington believed that in the world there are only two people who understand the essence of the theory of relativity — is Einstein and Eddington himself.

100 years later, the situation has changed little. Boast of understanding the essence of the theory upon which the modern physics can not more than 1,000 people worldwide. This figure refers to the German physicist Klaus Kiefer of the University of Freiburg.

Most people simply do not know what time, can not grasp this concept and relate it to the overall picture, along with other physical phenomena and quantities

According to Kiefer, in practice, this means that most people simply do not know what time, can not grasp this concept and relate it to the overall picture, along with other physical phenomena and quantities.

According to the American physicist Martin Rockwell, therein lies the contradiction entertaining. People do not really understand what is time, to believe that it can not go on, and left it very tempting idea for fiction writers.

Meanwhile, even before the recent experiment CERN some scientists have expressed doubt that the dream of time travel is a bad job. The basic contradiction can be stated in simple language so, says Rockwell. According to Einstein, is a space-time with their rigid laws, and make changes to their work only when it comes to objects with a monstrously large mass, as well as those that are moving faster than the speed of light, which is fundamental to the space- time.

Inside the black hole no laws of physics, space and time coordinates are reversed, and the journey in space becomes time-travel

For objects with a large mass, the situation is more or less clear. In the universe, there are black holes with a huge mass of the space-time around them bent.

It is assumed that the black hole is not the laws of physics, space and time coordinates are reversed, and the journey in space becomes time travel.

Here you have a real time machine, Rockwell notes. However, the practical benefit to mankind that knowledge does not carry. Black holes at hand is not, and near them the stars and planets, not to mention the much smaller objects are monstrous danger of annihilation.

To create a time machine to use the large gravitational forces. In other words, to simulate a black hole.

Based on this knowledge, Amos Ori, a physicist at the Israel Institute of Technology, advanced the theory that in order to create a time machine to use the large gravitational forces. In other words, to simulate a black hole.

Ori created a mathematical model that describes a time machine, but acknowledges that implementing it in practice impossible, mankind has no such technology.

"It's not scary — says Rockwell. — 30 years ago, a video call between two cell phones seemed a fantasy. Technology does not stand still. "

Applications for the collider

Similar views shared by researchers from Vanderbilt University, Tennessee. Moreover, time travel, however, is much less colorful than in fiction can be a reality very soon.

According to Thomas Wyler and his colleagues, the time machine can become infamous Large Hadron Collider — seduced tabloid character of modern science.

Time travel, however, is much less colorful than in fiction can be a reality very soon.

Collider is used to experiment with acceleration and collision of elementary particles. New particles produced in such a collision, can carry information in the past.

"In words like pure speculation — recognizes Wyler. — But there is no contradiction with the laws of physics. "

Wyler and his colleagues theorized that with collider will be found not only the famous Higgs boson — the mysterious particle, which gives matter its mass (for the sake of her quest in the first place and was built Collider). Scientists believe that there will be another particle, called the Higgs singlet, which, according to Wyler, will be able to move in time.

However, the scientist is convinced that time travel will be limited to these particles. "One can not go back in time and make a move that would affect his birth" — one stroke crosses hope dreamers Wyler.

One can not go back in time and make a move that would affect his birth

Yet from the opening of such a method of time travel is its use. If scientists learn how to control the "itinerant" Higgs particle, it will be possible to send messages to the past.

Dream a little, we can assume that such messages will warn about accidents or catastrophes, suggests Rockwell. In other words, it is still to be traveling in time to good use. And the past can be changed.

Immediately after the publication of a group of scientists at the Wyler collapsed wave of criticism from the less optimistic counterparts. "Travel back in time any particles in principle impossible," — is adamant that the German scientist Dieter Lust of the Max Planck Institute. For the simple reason that in modern physics there is a principle of causality: if something happened before, and something later, it is impossible to change, says Lust.

Uyler dismisses the criticism. "The law of cause and effect relationship has never been proven — he says. — For me, mathematical logic is stronger than human logic. "

Modern physics, there is the principle of causality: if something happened before, and something later, it is impossible to change, says Lust

Giants of modern physics in general sympathetic to refute (or at least partial revision) theory of relativity and admit of the possibility of time travel.

So, for example, changed his mind the famous physicist Stephen Hawking, previously stated categorically that time travel — it's fantastic.

Kiefer says that the equations admit traveling, but with one caveat. They are possible only up to the moment, when it created a time machine.

"That is not going to antiquity, — explains the researcher. — You can only build a time machine, wait a while and then go back in time to the moment of its creation. "

According to Kiefer, perhaps this explains the fact that we still have not received guests from the future.

You can only build a time machine, wait a bit, and then go back in time to the moment of its creation

However, despite the skepticism with regard to time travel by venerable scholars getting smaller, how to realize this dream of science fiction, in practice, still unclear. In fact, do not even know how to approach this problem. Applied Science in modern humanity while far short of theoretical physics.

The easiest way to start a journey in time — do nothing and wait for the time machine is formed by itself, ironically Rockwell. And finally, remember good joke Sheldon Cooper, a character in the popular series The Big Bang Theory. "If I'd invented a time machine, I would have gone back to the past and would have told her about himself," — said Cooper.
