Time Travel - A Possibility or Just the Stuff of Science Fiction?

It 'was written hundreds of dog books, subject The subject of fantasy for everyone at one time or another, and the government has actually spent on research at one time or another over the Internet. If you do a search on the Internet for time travel are millions of voices on it, and hundreds of websites devoted entirely to dog talk. Would not it be nice if you could travel back in time? You may correct the mistakes you made in your life, consider a period of time that interests you, let alone build a financial empire on the knowledge of events. From H.G. Wells' The Time Machine, the concept of time travel was one of the main points of science fiction. Some of my favorite authors are David Gerrold The man who folded himself and The Light of Other Days Stephen Baxter and Arthur C. Clarke.So really is time travel possible? First of all we are all travelers have time in the sense that time moves forward, and at the same apparent rate of speed, for all of us. There appear to be obstacles to accelerate physics in the forward momentum of time in one way or another. Cryogenics is a much written about as a method of travel "forward" time, lowering the body temperature above absolute zero for a while 'to stop almost metabolism as a way to Sleepaway millennia. The practical obstacles to putting this out any possibility of this in the future. Although simple organisms were frozen and returned successfully, the human body is too complex to survive the process but because of the crystallization water and other factors. Another method of differential acceleration time is the time because of relativistic effects of high velocity.According Theory of Relativity of Einstein, as the object approaches the speed of light is one of the effects of time dilation. As relativistic velocity of an object increases the passage of time slows down for it in relation to a non-moving object. Take for example a spacecraft traveling at 10% the speed of light, or 18,628 kilometers per second. If this imaginary ship maintained this speed for 24 hours (according to our watches at home), then at the end of those 24 hours only about 23 hours, 53 minutes would be spent on board the spacecraft. Much higher speeds in a fraction of a percentage of the speed of light to have connections to be established in order to obtain a very noticeable effect. Take this same ship and accelerate to lightspeed 0.999999 (or 186,281.81 km per second) and something really weird happens, do something more like a journey through time. If you take that on a spaceship joyride at that speed for 24 hours to the traveler and the return home, you will find that almost two years have passed Earth.In in reality, this has been observed in experiments in which atomic clocks have been sent on airliner to observe the effects of time dilation. The difference was observed as expected, helping to support the theories of Einstein. Of course, the difference was small, measured in nanoseconds. Unfortunately for all aspiring time travelers, the type of speed necessary for the relativistic effects are well outside of our technology silent. The fastest spacecraft yet launched the Helios probe were sent to study the sun in the '70s. They reached a speed of about 158,000 mph, or about 44 kilometers per second? This is 0.02% the speed of light, yet not near speeds.And relativistic as regards the possibility of traveling back in time This makes great material for science fiction, but the data here does not seem promising. Physicists have been able to imagine circumstances in which time travel some functionality may be permissible under the laws of physics, but the energy levels and requirements of exotic matter seem to be well beyond anything we can reach any time soon. Some have suggested that wormholes can be a bridge to other worlds, distant parts of this universe, or at other times. Wormholes remain a theoretical concept, neither proven nor dis-proven to exist. It seems that for practical purposes the universe (at least temporarily) be denied us the opportunity to revisit our past directly. Then we return to a discussion of what the possibilities would be if time travel did exist.First we need to look at the fact derived from modern physics that space and time are related aspects of the topology of our universe. In other words, our universe is composed of three observable dimensions of space and time. Put together a theory that explains the existence of our universe some time and space that combines into a single continuum. Assuming this is true, it follows that there should be a parallel measure in the space equivalent to measurements over time. It may seem absurd to talk to measure the space or time in seconds in miles, but the two are tied together by the speed of light. Therefore it follows that to convert a second time in the distance, we just look as far light travels in one second. Would be about 186.282 miles, or three quarters of the distance to the moon. This means that traveling back in time one second would be equivalent to traveling nearly the distance from the moon. Then there is the fact that a change in position in time means having to adjust to the movement of the Earth, sun and the galaxy as they rotate and revolve. Much harder than it seemed, huh? Ok, let's pretend to overcome this obstacle and achieve real, significant travel time. Could go back in time and kill your grandfather in his previous life, ensuring that you will never be born? Time travel is full of paradoxical as this investigation. For most cases this can be overcome by inserting the quantum mechanical concept of time travel, and branching realities.Quantum mechanics is a field theory developed in the first quarter of the twentieth century, Which through the work of Niels Bohr, Pauli, Planck , Heisenberg and Schrodinger. These basic principles are a matter at a fundamental level there is a cloud of uncertainty and probability. Heisenberg uncertainty principle states that you can not measure both the position and momentum of an elementary particle, because the act of observation changes the outcome. In this branch of physical cause and effect is said to break down and you can not say that the probability of something that is true. The most famous example of what quantum mechanics means in the real world has been given as a thought experiment by Erwin Schrödinger and is known as Schrödinger's cat. Here follows: A cat is placed in a sealed box. Attached to the box is a device containing a radioactive nucleus and a canister of poisonous gas. This apparatus is separated from the cat in such a way that the cat can in no way interfere with it. The experiment is set up so that there is exactly a probability of 50% of the nucleus decaying in one hour. If the nucleus decays, will emit a particle that triggers the device, which opens the container and kills the cat. If the core does not deteriorate, then the cat remains alive. According to quantum mechanics unnoticed the nucleus is described as a superposition (which means that exists in part as each At the same time) of "decayed nucleus" and "decayed nucleus". However, when the box is opened the experimenter sees only a "decayed nucleus / dead cat" or "decayed nucleus / living cat." The paradox of this experiment is that the cat is said to be both alive and dead until someone opens the box. (* No cats or any animals were harmed in the writing of this article). This paradox can be resolved if we say that instead of being both true in a reality, that reality in reality into two branches. In one universe the cat is alive and in the parallel universe is dead. In this way our universe is constantly splitting into alternate universes where # is enclosed all possibilities. This also solves the paradox of time travel. When our time traveler comes back and makes changes in the past would have been about creating alternate universe without destroying the other. In this way, as he or she has continued to make changes, our time traveler would never be able to return to their original timeline, even if he could create a similar one with the right changes. All the possibilities and implications of a scenario like this investigation are presented in a spectacular science fiction novel The man who is bent by David Gerrold.In synthesis, time travel is a very funny concept for science fiction, and really take in a some plausibility concepts of modern physics. But as a practical application, is not likely to become a part of our lives any time soon. Of course, not being a time traveler himself, I can not speak to tell certainty.Time. [ABSTRACT] It is a hundred books written on the subject of fantasy for everyone at one time or another, and the government has actually spent looking at one time or another subject. If you do a search on the Internet for travel time can be found on millions of records and hundreds of websites devoted entirely to talk about it. Would not it be nice if you could travel back in time? They may mistake you made in your life to correct, to study any time period that interests you build, to name a financial empire on prior knowledge of the events. From HG Wells' The Time Machine, the concept of time travel is a major product of science fiction. Some of my favorite reads David Gerrold is the man himself and in the light of other days of Stephen Baxter and Arthur C. Clarke.So folded really time travel possible? First of all, we are all travelers have time in the sense that time moves forward, and at the same apparent rate, for all of us. It seems physical obstacles in order to be an acceleration of the forward movement of the time in one or the other. Cryogenics is a concept as much about method of travel "forward" the time wrote, lowering the body temperature slightly above absolute zero to almost metabolism as a way to stop sleeping away millennia. The practical obstacles to this, not to do so, at this point in the future. Although simpler organisms successfully frozen and returned to the human body is too complex to survive still in the process because the water of crystallization and other factors. Another method to speed up the time differences are due to relativistic effects of high velocity.According theory of relativity of Einstein, as an object approaches the speed of light is one of the effects of time dilation. As a relativistic object increases, slows each course of time compared to a non-moving object. Take for example, a spacecraft with about 10% of the speed of light, or 18.628 miles per second. If this imaginary space ship stopped this rate is constant over 24 hours (according to our watches at home), then at the end of 24 hours, only about 23 hours, 53 minutes would have happened on board the spacecraft. Much higher speed in a fraction of one percent of the speed of light, have reached a truly remarkable effect can be obtained. Take the ship itself and accelerates the speed of light in 0.999999 (or 186,281.81 miles per second) and something really weird going to get something more like a journey through time. If this ship will take you on a return journey with this speed for 24 hours to check the traveler and go home, you will find that almost two years before Earth.In timeliness, this has been experimentally observed when the atomic clocks are been sent to watch on planes, the effects of time dilation. The difference was observed, as expected, helping to support the theories of Einstein. Of course, the difference was small, measured in nanoseconds. We apologize for any aspiring time traveler, the kind of speed required for relativistic effects are far beyond our technology. The fastest spacecraft yet launched the Helios probe were sent to study the sun in the '70s. They reached speeds of more than 158,000 mph, or about 44 miles per second speed that is about 0.02% of the light, near speeds.And relativistic yet, what about the possibility of a trip back in time, this ideal material for fiction-is? But the data do not seem promising. Physicists are some circumstances in which time travel may be authorized under current laws of physics, but the requirements of exotic matter and energy appear to be well informed on everything that we've probably reached in the near future. Some have suggested that the bridges wormholes may be other universes, distant parts of the universe, or at other times. Wormholes remain a theoretical concept, neither controlled nor dis-proven to exist. It seems that for all practical purposes, the universe (at least temporarily) has denied us the opportunity to reflect on our past directly. So let us for a discussion on the possibilities of what would happen if time travel did exist.First all, we have deduced from the fact that modern physics space and time are aspects of the topology of the universe, turning our gaze. In other words, there is a universe of three dimensions of space and time observable. The compilation of a theory that explains the existence of our universe requires the combination of time and space continuum. Assuming that this is true, it follows that there is a parallel measurement in the measurement space at the time of its equivalent. It may be silly, to measure the space-time in seconds or miles, but the two are tied together by the speed of light. It follows that convert to a second of time in the distance, we see how far the light in a second. This would be about 186282 miles, or three quarters of its distance from the moon. This means that 1 second goes back in time almost synonymous with the distance it would travel to the moon. Then there's the fact that mean a change of position in time that is adjusted for the movement of the earth, the sun and the galaxy in which twist and turn. Much harder than it seemed, huh? Ok, let us overcome this obstacle and achieve real, significant travel time. Could go back in time and kill your grandfather early in his life and assured that you will never be born? Time travel is full of paradoxes like these. In most cases this can be through the inclusion of quantum mechanics the concept of time travel, and branching realities.Quantum mechanics is a field theory, in the first quarter of the twentieth century through the work of Niels Bohr, Pauli , developed to overcome Planck, Heisenberg and Schrödinger. These are assumptions that exist at a fundamental level of matter as a cloud of uncertainty and probability. Heisenberg uncertainty principle says that it is not possible to measure both the position and the momentum of elementary particles, because the act of observation changes the result. In this branch of physics, cause and effect is said to break and you can only say that the probability of something real. The most famous example of what quantum mechanics has been given in the real world as a thought experiment by Erwin Schrödinger and is known as Schrödinger's cat. Here follows: A cat is placed in a sealed container. The box is a device containing a radioactive nucleus and a canister of poisonous gas. This device is the cat so the cat is in no way interfere with him separately. The experiment is such that falls only a probability of 50% of the base set in an hour. When the nucleus decays, it feels a particle that triggers the device, which opens the container and kills the cat. When the nucleus does not disintegrate, then the cat is still alive. According to quantum mechanics, the unobserved nucleus as a superposition (that is partly the same as the case may be) of "decayed nucleus" and "decayed nucleus" described. However, if the box is opened the experimenter sees only a "decayed nucleus / dead cat" or "decayed nucleus / living cat." The paradox of this experiment is that the cat is said to be dead and alive until someone opens the window. (* No cats or animals of any kind were injured in the writing of this article). This paradox can be resolved if we say that the real place, both in reality and in reality are actually two branches. In one universe the cat is alive and in the parallel universe, is dead. In this way our universe is constantly splitting into alternate universes where every possibility, it has captured. This also solves the paradoxes of time travel. When our time traveler makes changes and returns in the past, you are creating an alternate universe, without the other would. In this way, as he or she continues to make changes, our time traveler would never be able to return to their original program, although it could make love with the right changes. Everything about the possibilities and implications of a scenario like this is spectacular in the science fiction novel, The man who has bent, David Gerrold.In In summary, time travel is a very funny concept for science fiction, and has actually a degree of plausibility of some concepts of modern physics. But as a practical application, it is likely that part of our lives in the near future. Of course not, when a traveler the same time, I can bet is to talk certainty.Time.
