23 May They discover a theoretical model of journey to the past

Amos Ori israeli scientist has discovered a theoretical model for the trip in time which may allow future generations go to the past. Their calculations show that a loop space can be built without the need for exotic matter, only from ordinary matter and energy density positive. The creation of this loop depends on minimum initial conditions in which the israeli team works.

A theoretical model of a machine able to lead us to the past time has been developed by the physicist Amon Ori, of the Israeli Institute of technology, the Technion http://pard.technion.ac.il/, as announced in an article published in the journal Physical Review D http://link.aps.org/abstract/PRD/v76/e044002 for the month of July. The full version of this article can be found at Arxiv http://arxiv.org/PS_cache/gr-qc/pdf/0701/0701024v3.pdf

In this article, Amos Ori presents a theoretical model based on equations that describe conditions that, if they could be established, would allow the construction of a time machine. This hypothetical time machine would be the space time itself, according to the author of this article.

His research on the journey through time is based on the increase in the curvature of spacetime, considering that the arrow of time can get screwed on itself forming a loop. Amos Ori explains in this respect: "we know that the (space-time) curvature occurs constantly, but we have wanted to obtain a curvature sufficiently strong to give a form that leads to the time lines to form" closed loops… We have tried to find out if it is possible to manipulate space time to develop it in this way."

It operates single

He also explains that if the initial condition is achieved, the time machine would work by itself, without any intervention. And gives an example: If a ship Cannon fires a howitzer, once the shot has been there to do anything, the howitzer will go by itself towards its goal, led only by the laws of physics. Their calculations show that the loop space can be built with ordinary matter and energy density positive, but adds that it is still necessary to resolve the issue of the stability of this machine so that it can become a time tunnel.

What is really important in their contribution is that, according to its calculations, the creation of a time machine depends on very small initial conditions which, although they are very difficult, if not impossible, to obtain, nowadays constitute the objective of the work of this team of Israeli physicists.

Amos Ori ensured that a time machine would not require exotic matter to be built and would use the vacuum that exists in space to travel through time. According to his previous theory, it would be possible to create conditions that are potentially capable of creating a time loop without using exotic matter.

Although Amos Ori has not been the only physicist in formulating the ability to travel through time, other physicists have identified a number of possibilities, particularly the use of exotic matter, to create a curvature of spacetime able to change the direction of the arrow of time.

Quantum physics says that the exotic matter exists, but in such tiny quantities that it a time machine could never be built. Amos Ori has solved this difficulty opening up other possibilities for getting the machine of the time, without the need for exotic matter. Amos Ori system could allow our descendants in a distant future travel back in time, according to Newswise on release http://www.newswise.com/articles/view/532037/, but clear: we will not go to the past because our ancestors we have not stopped this infrastructure for us.

You have to wait

According to Amos Ori model, if the intended loop space was created on January 1, 2008, and twenty years later to be used for the first time, upon entering the loop would be becoming of January 1, 2008.

The machine of the time, in this case, would be in practice as a tunnel temporary space in which the entry is subject to the evolution of the time, but whose output is still at the time of its creation. Therefore people of 2007 not could travel to the past, only could do it that lived once had managed to create the loop space of Amos Ori.

According to this physical, it is possible to get the curvature of a space-time in a particular direction, in order to make possible a return in time in a parallel space-time. The machine itself becomes a spacetime, explains its creator, and the mere fact of its existence is what allows to conceive of the travel to the past. "Today creating this time machine, we make possible the return to our time of future generations", explains Professor Ori.

Theory of journeys in time

Since Einstein, we know that space and time form four continuous dimensions. That means, for example, that if a planet or a star warp continuous space-time, this phenomenon alters also the geometry of the space and the passing of time for an outside observer.

At the time of Newton thought that the Moon orbited the Earth by the attraction who land on it. We now know that it is not so, but Earth distorts space-time fabric forcing the Moon around the Earth.

On a microscopic scale, quantum physics teaches that the gravitational interaction is the origin of this attraction, generated by the exchange of elementary particles.

The theory of relativity and the Quantum described as well a means to bend space-time to microscopic scale and allow such a person to travel through time. If space-time, can warp just like any body does, it can be assumed also that time can bend with space, which is one of the foundations of research on travel in time.
