Some physicists believe and try to demonstrate that the weather does not have to flow in only one direction and that the messages can be sent in the past from the future.
The events in the future result of what has happened in the past, it is quite normal and expected a causal relationship to which we are accustomed in our world. But when it’s “expected” to be transferred to the micro, or micro particles, then our laws of physics cease to apply, including the path known Hawking “arrow of time” in one direction is no longer so sure where it goes !
Can the future influence the past ? As strange as it may sound, but physicists demonstrate how time may be running backwards. The new experiment has made confusion in the setting of what is possible and what is not, indicating that at the quantum level this concept, apparently, does not exist and it’s quite possible that future events may affect the past. Because, if something is happening in the micro-world, somehow can reflects and transmits on a macro level, and there is no reasons to be doubtful, then the foundations of classical physics are seriously questionable.
What is it ? Physicists have questioned how helium atoms react when firing through the lattice created with lasers. They set up a second laser grid after the atom went through first. From this they learned that the random setting other grids determine whether an atom to appear as a particle or as a wave when passing through the first grid. This suggests that the future impact on the history of atoms, the researchers say.
Dr. Andrew Truscott physicist at the Australian National University who led the expert team, says: “At the quantum level, reality does not exist if you do not look into it. Atoms are not traveling from point A to point B. Only at the end of the trip when they measured it happened that their behavior as a wave or as a particle has been in existence. ”
Experiment delayed decisions
The reason is that when a scientist tries to observe a photon or atom moving at high speed, for example, it can be seen only as a particle or a wave. But in the new experiment, the researchers found the effect, which appeared when they tried to observe the atom, and which is determined by whether the atom be seen as a particle or a wave.
In the journal “Nature Physics”, which published the research results, we note that it was based on a proposal from John Wheeler in 1978, who called it “an experiment delayed decisions in the mind”, as one version of the experiment double hole in which the light strikes the narrow openings in the bulkhead, namely the screen.
Sent through an opening, a ray of light appears on the wall behind the barrier as when photons appear as particles, but when he set up a beam of light, they act like waves. Wheeler’s idea was to introduce another barrier behind first see whether the photons remain in the same condition when you go through both.
Until now it was impossible to run such an experiment until the scientists replaced photons with atoms of helium and physical partition grille created lasers. In this way they were able to accurately measure what happens when an atom has passed through another obstacle, placed randomly in time. They found out that without such particles traveling in one direction, and with both barriers, he behaved like a wave, moving in multiple directions.
As the researchers measured the time atoms through the first grid before the second set, it can be concluded that potential adding of another grids already affected the atom. “This means that if the atom goes on a certain way or ways, then it will affect on the other atom “, summarizes Dr. Traskot. Or, in other words – the future affects the past !
Assumptions about the interference as possible causes of these results when it comes to light that more figures as wave, sound implausible, but still unusual in terms of atoms because atoms are complex particles that have mass, is considered by his fellow Roman Khakimov, a PhD student at the Australian National University. “Photon is very simple. Atom has a certain mass and is associated with magnetic and electric fields, so that it’s more in consonance with its environment.” explains the scientist.
How to send news back in time ?
National Aeronautical and Space Administration, better known as NASA, does not hide its interest in research into unknown areas of physics, announcing that it wants to create a deeper understanding of the nature of time in space, gravity, inertia, the quantum vacuum and other fundamental phenomena of physics. However, when it comes to the study on the possibility of surgery to receive a message before sending, it seems that they are still skeptical.
This can be done, says John Cramer, a physics professor at the University of Washington, one of the biggest supporters of experimenting with so-called “quantum nonlocality” (when the results of measurements performed in one part of a quantum system with a non-local influence on the other, remote part, in the sense that quantum mechanics can not predict the outcome of some measurement which should be carried out in this work).
Kramer draws a distinction between “normal”, Newton, and quantum mechanics, and the phenomenon of quantum nonlocality, also known as “EPR paradox” – by Einstein, Podolski and Rosen who faced with it in 1935 and considered it “strange error” Einstein described it as “spooky action at a distance” for which it was held that quantum mechanics is wrong.
“Essentially what happens is that you have photons exceeding one direction across the table and photons across the board go in another direction, and when the influenced photons on the left hand, something happens and change on the right side of the table. Imagine a picture of two people, Bob and Alice, each of them receives these photons. They, Bob and Alice, can be separated by light-years, the quantum mechanics really does not matter how far. The question is whether it can establish communication to Alice to act according to its photon so it can create a signal that Bob can accommodate up to its end of the system. If such non-local communication is possible, it changes all the rules that we know about communication, because the signal is sent whenever that Alice did measure and was admitted whenever that Bob did the measurement, “explains John Kramer principle” of quantum involvement “.
Kramer idea is to practically check controversial assumption quantum physicists that particles of light could go back in time, which, he believed, could be accomplished if, with the help of crystals, split photon and determine how he will behave and will “get lost” in the past!
Hawking is wrong!
For such an experiment, Kramer needed financial support so he contacted NASA Institute for Advanced concepts (NIAC) and the Agency for Defense Advanced Research Projects Agency (DARPA). For now, DARPA is more interested in a kind of “liquid robot”, as in the movie “Terminator 2″, and also for the idea of ”Cyborg insects” – half robot half insects. The account is taken and the realization of the idea of the famous science fiction writer Arthur C. Clarke on geo synchronised elevators to space, but not the proposal of John Kramer!
“I heard that NASA closes NIAC so do not expect any financial support from their side. And the man from DARPA decided that’s what I’m trying to do even for them, too strange, “says Kramer.
John Kramer, however, has an enviable reputation in places such as the Brookhaven National Laboratory and CERN, and he does not hesitate to say that he thought that the celebrated physicist and author of “Brief History of Time,” Stephen Hawking is wrong, at least with regard to time.
“Hawking has this ‘arrow of time’, the idea of claiming that the weather can flow in only one direction, it goes forward” says Kramer. “The idea is attractive, stylish, and definitely makes sense on the basis of intuition, because it is the only way that we’re experiencing time, but does not fit so well in the mathematical and experimental evidence of quantum theory. Quantum mechanics, which describes the bizarre behavior of matter at the atomic and subatomic level, contrary to the physics based on intuition. I am now in a situation where I have a pretty convincing mathematical model that shows the way to accomplish nonlocal communication as required to be tested experimentally, “says the scientist.
The laws of quantum mechanics, appear to indicate that there is not a clear boundary between the world and our awareness of its existence. That is, the world around us depends on our perception of it, and even that may be changed depending on how you look. Experiments at the subatomic level tend to support this idea, but the only problem is how to “persuade” two photons that constantly communicate with each other even if they are distant from each other and a few light years away, which means a speed exceeding – the speed of light!
