Albert Einstein’s theory of general relativity suggests that time travel to the past is possible via turning wormholes and/or black holes. The actual technical usefulness of really performing such journeys need not issue us because this essay is in the world of the thought experiment. Now Stephen Hawking states time take a trip to the past is not possible since he proposes that there is such a thing as a yet undiscovered Chronology Protection Opinion that prevents this and therefore makes the world safe for historians. I have actually created an unified theory of time travel into the past that incorporates Einstein’s general theory of relativity; Hawking’s Chronology Defense Guesswork, together with other assorted bits like parallel universes that are tossed into the mix.

Time travel is a staple in sci-fi stories, books, movies and TELEVISION series. And, time travel is possible – in theory. We all understand about travelling to the future which we do at the rate of one second per second whether we like it or not. Apart from that, if one journeys at close to light speeds relative to your place of origin then you can travel to the distant future (with respect to that place of origin) without aging a comparable number of years (the twin paradox). Travel to the past is obviously enabled too, via the weird physics inherent in turning worm holes and possibly Black Holes which is where Einstein’s general theory of relativity enters into play. The issue there is that theory of relativity predicts worm holes, if they exist at all, will exist for nanoseconds and be really small to boot, and hence not extremely useful in the foreseeable future for the purposes of time travel. Due to the fact that we do not know exactly what the inside of a Great void is, and where it leads, if anywhere, current thinking suggests that delving into Great voids are a better means for committing suicide than for traveling to the past, but the jury is still out on that one.

Anyhow, the enjoyable bit about time travel is the different paradoxes that develop, the most well-known one being the grandfather paradox. That is, what if you take a trip back in time and kill your grandpa prior to he sired your dad (or mother). If you did that it indicates that you could never ever have actually been born, however if you were never ever born you could not return in time to kill your ancestor. This is the sort of things sci-fi authors (and theorists) love – ditto physicists! My preferred time travel paradox however is the one where you get something for nothing. State you have this edition of “Hamlet”, and you desire Shakespeare to sign it. So back you go in time to Shakespeare’s era. You knock on his door, however the house cleaner states he’s out for the day but if you leave the book he’ll sign it and you can visit and gather it next morning. When Shakespeare gets home, he sees the book, reads it, and is so impressed he invests the night making a copy. You return the next morning, gather your now autographed edition of “Hamlet”, and return to today day with your now extremely important book. The question now ends up being, where did the original “Hamlet” originated from? You didn’t compose it; however Shakespeare didn’t either as he plagiarized your copy which he then passed it off as his own work.

Another favorite is you fulfilling yourself. Say you’re 50 and not all that well off. You get the fantastic idea to take a trip back in time and encourage your more youthful self to purchase some stocks you understand will pay off big time in the future down the track. And so it comes to pass that your younger self so invests, and ends up being filthy rich, only, in leading such a jet set, passes away of a cardiac arrest at the age of 45! Or you always regretted not proposing to the love of your life when you were young, and thus return and encourage your younger self to muster up the guts and do so. He does, but as they fly off on their honeymoon, the aircraft crashes with no survivors. In some cases you do not know when you’re well off.

Or if you can travel back in time, then naturally others can to. Naturally there’s going to be lots of individuals thinking about specific events, maybe even at the time, apparently unimportant occasions (yet which end up in the long run to have had major impact( s)). Therefore you may have any number of individuals going back to particular historical focal points, each with their own particular agenda (the majority of which will be equally special), and ultimately causing havoc. I mean if individual one goes back and influences an event producing a brand-new result, then individual two may return and attempts that outcome and things get modified again, which will then prompt person three to go back and influence things more to his preference, and so on. Simply puts, history would never ever be fixed, rather always be fluid. The world is not safe for historians. Considering that we believe that history (or the past) is fixed, then that exactly what’s written on your history book page today will not change overnight. Therefore, you have actually most likely concluded that time travel can not occur, will not take place, and has actually not occurred, nevertheless much you yourself might want to go back in time yourself and change something. (Do not we all actually want some previous something, personal and insignificant, or maybe something of significant significance could be changed and you ‘d be that instrument of change?).

Its paradoxes and scenarios such as the above that triggered Stephen Hawking to postulate that there is as yet an undiscovered law or principle of physics which restricts time take a trip to the past – he calls it his ‘Chronology Forecast Opinion’. Since we have never ever seen, according to Hawking, to the best of our knowledge at least, at any time tourists – travelers or historians – from our future, he’s most likely right.

So, putting it all together, here’s my theory of time travel: my combined theory of time travel, at least to the past.

Relativity theory has passed every experimental test thrown at it, so the theory isn’t in much doubt and one can have a high degree of confidence in what it anticipates, even if that prediction is currently beyond any experimental test. Theory of relativity enables time travel into the past, however, viagens, only to parallel universes (otherwise known as alternative or mirror or shadow universes) where no paradoxes can occur.

Why only parallel universes? The methods and means by which you can utilize theory of relativity to time travel in reverse includes turning Black Holes or wormholes. There are major factors behind the speculation that exactly what’s on the opposite of a Great void and/or wormhole is another universe. So, for that reason it’s relativity’s time travel allowance, however probably to another universe. The Black Hole or wormhole ‘exit’ isn’t within our Universe.

Whatever you perform in that parallel universe is predetermined. It’s fate. It’s fate – all due to the fact that causality guidelines. For that reason, there are no unexpected ripple effects besides exactly what was predestined to take place. You were implied to be there and do exactly what you do. Therefore, there will be no paradoxes developing.

Astrophysicist Stephen Hawking has actually proposed his Chronology Security Conjecture that restricts time take a trip to the past within your very own universe because of the possible paradoxes that might occur. Why can’t you return in time in your own universe? That would imply that at a particular time and location you both were not (initially) and were (as a result of going back) present. That’s a paradox. And if you were to take a trip back in time to a set of time and area coordinates you were really initially at, then there would be two copies of you occupying the same space at the same time – likewise a paradox.
