Travels in time become a reality

05 May

Travels One of the leading theorists of modern physics British professor Stephen Hawking, a journey man in time and visit to the future – perhaps as the last – no.
Sensational article on his latest research findings, published in London weekly Sunday Times.
“Global science for a long time viewed the talk of time travel as a heresy, and I usually refrain from talking on the topic that I have not thought eccentric. But now I do not want to be overly cautious”, – said Hocking.
In his view, there is no theoretical obstacles to a man could go in the future, according to business newspaper “Sight”. To do this, however, need to create super-fast spacecraft capable of reaching 98% of the speed of light, says a scientist.

“Since the launch from Earth to this ship will need 6 years to develop a similar rate. As a result, it will change over time – for the people on board the vehicle it will slow down: they lived in a time of one day on Earth will be a whole year” – said the scientist.

He added that the creation of such a vehicle will quickly face the agenda of humanity, as will need to go beyond our solar system to save human civilization.

It should be noted that fantastic technology “wormholes”, without which it can not do hardly any work of fiction that directly relates to the topic, which deals with astrophysicist – the theory of gravitation.

In Einstein’s general relativity gravity is curvature of space-time. The calculations made by Einstein in 1910-ies were confirmed by a number of experiments and astronomical observations – the scientists found that massive bodies are deflected towards the light rays, and particularly large concentrations of matter in space and does work as a gravitational lens.

And from a mathematical point of view of space-time can not simply bend, and bend so as to make the same “tunnel” of which they write fiction, through which really is possible to reach other stars. This idea was originally taken by writers of very serious physicists – though not without certain nuances.

In his lecture “curved spacetime” that Hawking wrote in 1999, these nuances are analyzed. The scientist points out that the opening of “tunnel” a very large (in fact, unattainable in any foreseeable future) the energy density and, moreover, this energy must be negative. In other words, to create interstellar portals need something with negative mass and creating anti-gravity, and this “something” need a lot – so expect to jump to the stars should not yet. However, at about light speed space travel and move in the future still possible, but in the past – no.

The scientist noted that the theory that in time there are “holes” through which “can be accessed in the past, contrary to the fundamentals of science”, ITAR-TASS.

Recall that Stephen Hawking became famous for his discoveries in the field of cosmology and quantum gravity. The scientist studied in detail the “black hole” and came to the conclusion that they evaporate due to a phenomenon that has been called “Hawking radiation”. The professor also explained the paradox of the disappearance of information in “black sites”.

Even in 1963 Stephen Hawking was diagnosed with multiple sclerosis. Because motor neuron disease 22-year-old man for life was confined to his wheelchair. Later, he had problems with voice, and since 1985 the scientist talked to people solely using a speech synthesizer. Nevertheless, the professor recently led to an active lifestyle. He recently flew in a state of weightlessness in a special plane and was preparing to send into outer space.

At the same time, Stephen Hawking remains one of the most influential figures in the scientific world. He is a member of the Royal Society and Cambridge University, has served Lukasovskogo mathematics professor, who once belonged to Isaac Newton.

By Topic

Recently scientists have tried to analyze how mental time travel is reflected in the sensory-motor systems, which help regulate movement of people. It turned out that our perception of time and space strongly interrelated.

Psychologists Lynden Miles, Luis Naynd and Neil McRae of the University of Aberdeen conducted a study to measure this relationship in the laboratory. Participants were motion sensors, while remembering the past or were arbitrary future events.

Researchers have found that thinking about the past and the future can literally move us. The phenomenon became known hronosteziya: those who thought about the past, moved back, those same people who represented the future and moving forward.

The results suggest that hronosteziya may be based on processes that link the spatial and temporal metaphors (eg, the future – forward, the past – back) with our systems of perception and action.
