The theory of general relativity of Albert Einstein suggested that travel in time in the past is possible by rotating worms and / or black holes. The actual technical practice of driving these trips really do not need to worry because this process is in the field of thought experience. Now, Stephen Hawking says that travel in time to the past is impossible because it suggests that there is such a thing as a protection Conjecture Chronology that prevents yet discovered this and thus makes the world safer for historians. I developed it a unified theory of time travel in the past that integrates Einstein’s general theory of relativity; Protection chronology of Hawking conjecture, as well as other bits categorized as parallel universes that are released into the mix.
Travel in time is a staple in science fiction stories, novels, movies and TV series. And, time travel is possible – in theory. We all know that the way to the future that we do at a rate of one second per second, like the like or not. Other than that, if you travel at speeds close to the light in relation to their place of origin, you can go to a distant future (compared to this place of origin) a non-aged number of years equivalent ( The double paradox). The journey into the past is apparently also allowed by the strange physics inherent in the rotation of wormholes and black holes perhaps this is the general theory of relativity of Einstein comes into play. The problem is that the Relativity theory predicts that wormholes, if any, exist for nanoseconds and will be very small to begin with and therefore will not be very useful in the foreseeable future for travel time. Because we do not know exactly what is inside a black hole, and where it leads, if somewhere, currently thinking that jumping into black holes is a more useful way to commit suicide than traveling in the Past, but the jury is still on this point.
Anyway, the little fun about traveling through time are the different paradoxes that arise, the most famous is the grandfather’s paradox. In other words, if you travel in time and kill your grandfather before he becomes your father’s father (or mother). If you did that means you could never be born, but if you were born, you could come back in time to kill your ancestor. This is the kind of thing that science fiction writers (and philosophers) love – physicists! But my favorite paradox of traveling in time is the place where you get something for nothing. Let’s say you have this edition of “Hamlet” and Shakespeare lacks autographs. So, in time at the time of Shakespeare. You call your door, but the maid says it’s up to date, but if you leave the book, autografará and will pick you up the next morning. When Shakespeare comes home, he sees the book, the bed and is so impressed that he spends the night making a copy. Return the next morning, take your autographed now edition “Hamlet”, and now return to your now precious book. The question is now, where did the original “Hamlet”? Not what you wrote; But Shakespeare did not because he plagiarized his copy, which then went on as his own work.
