Scientists had believed time travel would be impossible thanks to the paradoxes which come with it, such as altering an event in the past. The most common example which comes up is: What would happen if you went back in time and killed your grandfather? If you were to do that, it would ultimately mean you were not born, which would mean you never had the opportunity to time travel. However, scientists now believe this would not be a problem, if the ‘many worlds’ or infinite universe theory is correct. The infinite universe theory dictates that every time a decision or action is taken, a new branch of a timeline is created where an alternate decision is made. Theoretically, this could mean there are an infinite number of versions of you based on an infinite combinations of decisions taken during a lifetime. And this would not only apply to you, but every other person, animal plant, atom, molecule and everything else which has ever existed in the history of the universe. Every time something happens, there is a new branch created. This would mean that if you were to travel back in time and killed your grandfather, it would not make a difference to your timeline as a new one would simply have been created, according to a new theory published in the online journal arX…
