Many scientists believe that time travel is impossible. Others believe that unknown physics may allow it. Debate on this issue has persisted for many years. The authors of an article published on the preprint server arXiv, which has not been peer-reviewed, decided to look for traces of time travelers on the Internet. In June 2009, the famous physicist Stephen Hawking, while at the University of Cambridge, decided to conduct an experiment. The scientist came up with the idea of ​​sending invitations to a party that had already taken place. The essence of the experiment was that if time travel were possible, then people who received invitations would come to the party, although they could not know about it in advance. Alas, none of the people Hawking invited showed up. Perhaps the time travelers simply did not want to be in the company of the famous physicist, or perhaps time travel is simply impossible. Stephen Hawking But a group of physicists decided to conduct their own experiment to find potential time travelers. To do this, scientists decided to search the Internet for information about significant events that appeared even before these events took place. According to scientists, only those who can travel in time can write a kind of prediction about a particular event that will take place in the future. The authors of the article suggested that even if people arrived from the future (and scientists decided that they certainly could not create a time machine in the past), they might accidentally leave some information on social networks during a certain period of time when some significant events were already known to scientists but had not yet occurred. Physicists actively viewed messages on various social networks and also monitored trending queries on Google. But no references to known events before they happened were found. The scientists also posted on various social networks a call for potential time travelers to send them an email. The essence of the experiment was that the email address was indicated later than the message itself with a call for correspondence. That is, the person from the future should have already known the email address at the time the message appeared. And again, no one wrote anything to the physicists. Yes, time travel is indeed a real thing. But it’s not quite what you’ve probably seen in the movies. Scientists believe that perhaps people from the future do not want to be known, and therefore do not leave revealing information traces. But there may be other reasons. “Even time travelers who want to advertise their presence may do so ineffectively,” the team writes in their paper, “those who want to hide their presence might make a revealing mistake, and those indifferent might or might not leave traceable Internet content.” The authors of the paper write that it may be physically impossible for time travelers to leave any lasting remnants of their time in the past, including even social media posts. Or maybe we physically cannot find such information, as this would violate some still unknown law of physics. “First, it may be physically impossible for time travelers to leave any lasting remnants of their stay in the past, including even non-corporeal informational remnants on the Internet,” they explained. “Next, it may be physically impossible for us to find such information as that would violate some yet-unknown law of physics, possibly similar to the Chronology Protection Conjecture. Furthermore, time travelers may not want to be found, and may be good at covering their tracks.” The post Searching for Time Travelers: Experiments and Findings by Physicists appeared first on Anomalien.com.
