(www.saludyciencias.com.ar) is no longer a science fiction novel. Neither a remake of the series The Time Tunnel. Much less of movies today some old-fashioned, like Back to the future. Now, September 2007, is a theoretical model of a time machine developed by a physical flesh and blood. A machine capable of carrying people into the past.
The researcher in question is called Amon Ori and works at the Israel Institute of Technology (Technion). Physicist presents a theoretical model based on equations that describe the conditions which obtained power, would build a time machine, as published in the journal Physical Review.
According to the Israeli physicist, creating a time machine depends on some initial conditions very small although very difficult, "are not impossible to achieve."
Foundations of Ori theories about the trip through time are based on increasing the curvature of space-time, whereas the arrow of time can go to curl in on itself forming a loop.
Pretty complicated to understand for mere mortals are not experts in the Theory of Relativity of Albert Einstein, the thing is, in words Ori Amon, thus: "We know that the curvature of space-time occurs constantly, but we have wanted to get strong enough to bend into a form that takes time lines to form closed loops. We attempted to see whether it can manipulate the space-time to develop it in this way. "
If the initial condition is achieved, the time machine would work by itself, without any intervention, as is, with the barrel of a ship: If the cannon fires a shell, once the trip has been nothing more to do but wait for the shell itself go towards your goal, driven only by the laws of physics.
To Ori, it is possible to get the curvature of space-time in a particular direction, in order to make possible a return in time in a parallel space-time.
Israeli physicist calculations show that the loop space-time can be built with ordinary matter and positive energy density (whereas normally the investigations so far have been directed to use particular area, specially made), but adds that it is still necessary to resolve the question of stability of this machine in order to become a time warp.
"The mere fact of the existence of the machine design is one that allows travel into the past-resume Ori, and excited. Creating this time machine today, we can return to our time of future generations. "
According to the model of Amos Ori, if the alleged time-space loop is created January 1, 2008 and will be used for the first time 20 years later. Of course when entering the loop will be returning to the 1st. January 2008.
The Time Machine, in this case, would in practice as a space-time tunnel in which the entry is subject to the evolution of time, but whose output is stationary at the time of its creation.
Therefore, the 2007 people could not travel to the past could only do they live after they had succeeded in creating the space-time loop Amos Ori.
