He says that, according to his calculations, events can exist both in the past and in the future simultaneously, independent of one another. Space-time will adjust itself to avoid paradoxes, thus allowing you to cause whatever mayhem you want throughout time without creating contradictions.<\/p>\n<p>If true, famous <a href=\"https:\/\/www.vice.com\/en\/article\/jos-can-say-so-lets-talk-about-time-travel\/\">time travel<\/a> stories like <em>The Terminator<\/em> and <em>Back to the Future<\/em> wouldn\u2019t be possible. A Terminator sent to the past to kill John Connor would not be killing John Connor in the future, theoretically. It would only kill John Connor in the past and space-time would find some way to adjust to ensure that John Connor is still alive in the future to continue to be a pain in every robot\u2019s shiny metal ass.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Good news for anyone with a hankerin\u2019 for going back in time to kill their grandfather before he had kids: a physicist named Germain Tobar from the University of Queensland in Australia says go for it since time travel paradoxes aren\u2019t real.
