Time Travel Issue Clarified by a Computer Program

Time travel issue that has left researchers confused for quite a long time and stopped the improvement of a time travel machine has been finally clarified by a computer program.

The grandparent enigma where a time traveler returns into the past and murders his own grandparent and stops the birth of one of his parents and thus kills himself – has at last been clarified.

According to Cosmosmagazine.com the matter is that if there is no time traveler, then how could he at all return in time and cause all of that?

The mystery is frequently stretched, in different appearances, to respect any activity that changes the past –, for example, Marty McFly keeping away from his mother’s affection, and making sure that she weds his dad, in Back to the Future.

In the meantime, physicists, for example, Stephen Hawking state that one cannot travel in the past and support this statement on the improbability of such causal chains.

Unquestionably, the quantum mechanics’ theory of “numerous universes” has been always been a probable answer.

According to this theory by going back in time one winds up in another universe, so any harm one may cause influences just that universe.

This is a possible answer to the problem however there should be many other worlds in order to be possible to jump in time with the time machine.

Settling the problem with only one world has proven to be more problematic.

At the moment, Doron Friedman, a computer researcher, has used computerized thinking to handle the issue, and issued his work publicly on the arXiv.

It is very hard to track time travel plotlines. Yet, Friedman made a program whereby one can precisely trace the forward and backward chain of occasions.

A simple form of the problem was taken, where the time traveller travels back in time and murders his own father.

At the point when Friedman’s program processed this plotline, logical inconsistency was observed – in particular that it is not possible for one to be born if one goes back in time and murders his dad.

What’s more, when Friedman tried to solve the paradox, the program processed many conceivable situations to discover the ones that were rationally reliable – i.e., where the child does not prevent his own birth with his deeds.

A big number of options were probable, evidently, however in his work, Friedman depicts only two. According to the first one the child (we can name him Marty) becomes his own grandparent. By travelling in time and killing his parent (George), Marty conceives a son who would actually be his dad.

It is some kind of answer, nonetheless radical causal exercise is needed (other than the offensive entrapment of Marty and his own grandma).

The second option of the program is all the more intriguing. The trick is that it just works if the father can go back in time as well.

The story is as follows.

Marty’s father George travels in the future one year, and conceives Marty before promptly travelling one year back – when his unborn child, Marty, comes and murders him.

Since George’s fast venture in the future enabled him to make his child, the problem is gone.

Without a doubt, it is difficult taking into consideration that the family progression is not any more convincing than the time-travel idea itself, however the calculation not just unimportant nerdery.

Friedman did not make his program to work only as a sci-fi scenario motor. His principle design is to process virtual reality situations to be used in exercise, or even mental recovery.

“Oppose to the real world, the computer enables you to ‘travel back in time’, alter something, and watch the results,” he stated. Each word processor has the possibility to change a mistake. Also, on the off chance that you commit an error in a computer game, you can come back to a former point and make another attempt. Moving in virtual reality could make you follow the outcomes of choices while being prepared for new employment .Or it could enable somebody in mental treatment to cope with the implications of a painful ordeal.

Maybe it is not so good for resolving family problems.
