of \u201cexotic matter,\u201d which is matter with negative energy, as opposed to the matter around us, which consists of positive energy.<\/p>\n<div id=\"today-2019472880\"

quantities.<\/p>\n<p>\u201cIn addition, other equations can be discovered that allow time travel without requiring exotic matter,\u201d explains Professor Shoshany.<\/p>\n<div id=\"today-559578436\"

that undo the need for time travel.<\/p>\n<p>A classic example of this is the famous \u201c\u00a0grandfather paradox\u00a0\u201d, where pundits ponder whether a time traveler would cease to exist if he went back in time to kill his grandfather when he was young.<\/p>\n<p>\u201cIn physics, a paradox is not an event that can actually happen, it is a purely theoretical concept that points to an inconsistency in the theory itself,\u201d adds the Canadian physicist.<\/p>\n<p>\u201cIn other words, the paradoxes of consistency not only imply that time travel is a dangerous endeavor, but that it simply cannot be possible.\u201d<\/p>\n<p>Theoretical physicist Igor Dmitriyevich Novikov attempted to solve the problem of time travel paradoxes with a self-consistency conjecture, which essentially states that you can travel to the past, but you cannot change it.<\/p>\n<p>But Professor Shoshany, along with his students Jacob Hauser and Jared Wogan studied time travel, and in a recent study they discovered that there are time travel paradoxes that the Novikov conjecture cannot resolve.<\/p>\n<div class=\"middle-entry-content\"><\/div>\n<p>\u201cWe show that allowing for multiple histories (or in more familiar terms, parallel timelines) can resolve paradoxes that the Novikov conjecture cannot,\u201d Shoshany writes.<\/p>\n<p>\u201cIn fact, it can solve any paradox you throw at it.\u201d<\/p>\n<p>According to his theory, when a person steps out of a time machine, they arrive in a different timeline, where they can do whatever they want, including destroying their time machine five minutes before they were supposed to use it.<\/p>\n<p>In this theory, changes to this new timeline would have no effect on the original timeline.<\/p>\n<p>\u201cAfter working on time travel paradoxes for the past three years, I have become increasingly convinced that time travel might be possible, but only if our universe can allow multiple histories to coexist,\u201d he continues. explaining the physical<\/p>\n<p>The team of researchers now seeks to formulate a concrete theory of time travel that complies with the law of general relativity.<\/p>\n<p>Professor Shoshany\u00a0adds\u00a0that even if they do manage to find such a theory, this would not be enough to prove that time travel is possible, but it would at least mean that time travel is not ruled out by consistency paradoxes.<\/p>\n<p>In short: multiple timelines would allow you to travel to a different timeline and kill your grandparents, let\u2019s ignore the \u2018why\u2019 for the sake of debate, without causing a paradox.<\/p>\n<p>Of course, once this happens, there is no reason to believe that that Universe will continue exactly as ours has.<\/p>\n<p>It is likely that the \u201cbutterfly effect\u201d of your arrival has changed it, it is also likely that you have selected a limited number of similarities, no matter how great they are.<\/p>\n<p>Still, this would be a (still extremely far-fetched) way to experience the past, without affecting the present or creating paradoxes.<\/p>\n<figure class=\"wp-block-embed is-type-rich is-provider-trinh-x\u1eed-ly-nhung
