GRANDFATHER PARAFOX FULLY EXPLAINED

Grandfather paradox fully explained.

Einstein's theory of relativity inspired scientists from around the world to begin imagining that time travel is theoretically possible imagine for a second that time travel became completely possible in practice suppose you decide to go back in time. For example to meet your grandfather whom you've never met, you know, the exact time and place where your younger grandfather. In the past when you go there since you entered the exact coordinates of his location The Time Machine lands right on your unsuspecting grandfather and crushes him to death. It turns out that now your grandfather does not meet your grandmother, which means that one of your parents won't be born and neither will you if you didn't come into the world then you couldn't possibly go back in time and kill your grandfather thus We see how the Paradox turns out physicists call it the grandfather Paradox many scholars use it as an argument against possibility of travel to the past. But I know the solution to this Paradox, which means that in the next 10 minutes,



 you'll also find out why you can't get in trouble by going back in time. And even if you seriously screw up though in just a few seconds, you yourself will understand so What's the solution to the time Paradox to uncover this secret back in the 1970s Russian physicist Igor novikov proposed the principle of self-consistency. This principle is based on the general theory of relativity According to which the fabric of space-time is curved following this curvature. There are special lines that prevent the violation of cause-effect relationships in time. I'm since time travel is only possible along these lines. It's impossible to change the past and influence the present and future the physicist Kip Thorne believes that there are wormholes right along these lines. These are hypothetical tunnels leading from one point in space-time to another such Wormhole suggest that all events are cyclical and self-consistent. This means that time travelers will not be able to change. Anything some physical barriers will stand in their way or there will be no opportunity to make a choice that could affect something therefore even if you try to kill your grandfather you wouldn't succeed. For example, if you point a handgun at your grandfather, it will misfire on every attempt to shoot him. But at the same time the gun will work flawlessly in any other case when the shop would not cause any changes in the cause-effect. Ships of space time later students at the California Institute of Technology Fernando echeveria and Gunner clink Hammer together with Kip Thorne expanded their understanding of wormholes and trying to solve the grandfather Paradox through a game of Billiards. They wanted to find out if a billiard ball could be thrown into a wormhole at an angle so that if they continued along a given path, it would exit the wormhole in the past. 

To collide with itself this event. Therefore would have knocked it off course preventing it from entering the Wormhole at all. However, through complex mathematical calculations. The researchers found that the physical features of the Wormhole itself are designed in such a way that they simply will not let the ball knock itself off course more precisely the ball can hit itself, but this will not significantly affect his path of travel the same thing. Will happen with your grandfather and the handgun he might tell you a story about the past when he was threatened with a gun by someone similar to his grandson or granddaughter, but his life story will otherwise remain unchanged suppose having all of this information about Nova calls principle of self-consistency and wormholes for the sake of curiosity. You start firing from your handgun at your grandfather because you're completely sure that the laws of physics. 

Not let you kill them. However the Happen the bullet impact with your grandfather's head in a panic you get into the time machine return to your time and find that your family Holman all of the traces of your existence are gone. The fact is that for the operation of the Nova called principle of work, there must be additional mechanisms that will cause the gun to jam or force your grandfather to dodge the bullets like Neo in The Matrix only. Only such laws of physics capable of preserving causation from the careless Hands of Time Travelers have not yet been discovered there for the entire scientific Community has rejected. No cause principle of self-consistency. So the grandfather Paradox requires a different solution fortunately such a solution exists and is given to us thanks to research into the behavior of light back in 1803. 

When scientists were arguing about what light waves or light particles are Thomas Young put an end to this discussion. He conducted an experiment in which he exposed a beam of light to an opaque screen with two slots. It was expected that two parallel lines of light would come out through the holes, but the light passed through the slot like a wave then other researchers decided to repeat the same experiment but But not with a whole beam of light rather with a single electron. It was assumed that the electron would pass through one of the two holes, but the astonishment of the scientists it's simultaneously made his way through both slots. Thus scientists discovered quantum mechanics in which an electron is both a particle and a way based on this physicist Hugh Everett proposed a theory of multi-world. 

According to which the universe is divided into two worlds one world in which an electron passes into the first Gap and a second world where it's like the other gap. This has a direct bearing on the case of your murdered grandfather. According to Everett's Theory after your grandfather's death. You've created a new alternate universe in which your grandfather dies after being crushed by a time machine. The same thing happens if you shoot your grandfather with a gun, but in the original world, nothing has changed grandfather is alive and well, you could still have been born after which you travel back in time and divided the universe into a similar principle is demonstrated in the short film one minute time machine where the main character each time traveling just one minute into the past kills himself in the primary World increase Copy of himself in the new alternate universe we could put an end to this but there's one more time Paradox that just can't be solved. It's called the ontological Paradox and is often contrasted with the grandfather Paradox. Imagine that you were a young man who went to the Past met a woman who later became pregnant from you if you were her newborn baby then when you grow up you go back in time. To conceive yourself this in turn will lead us to an endless cycle in which you don't have a clear visible origin. Let's turn to another example. Let's say you created a time machine and went to the past to deliver instructions to yourself on how to create this time machine. It turns out that any object information or person sent to the past starts an endless cycle in the origin of the object becomes. Unclear Paradox assumes that the past future and present are not defined which means that talking about time travel is impossible even in theory, but the numbers tell us something very different Einstein's gravitational field equation implies. The existence of such infinite time Cycles as experience shows many theories, mathematically deduced by Einstein far sooner or later confirmed in practice. All this does not guarantee real time travel according to the calculations of Stephen Hawking and Roger Penrose. There's an obstacle in the wormholes the so-called couchy Horizon passing through it. You'll be struck by an endless impulsive energy that will erase your entire past. However, Kip Thorne believes that this can be avoided if the Wormhole consists of a special collection. 

Kind of exotic matter, but this is a topic for another. Remember nevertheless most likely we live in the primary Universe which will only begin to split apart when Humanity learns to travel to the past or the future. Then many scientists will begin to disappear from this universe for the sake of research. It may turn out though that their discoveries will benefit only the residents of parallel universes. If you had such an opportunity, would you leave your native? Mention to start life from scratch in a parallel reality. Let us know in the comments.
