Physicists remain skeptical about that <a href=\"https:\/\/www.iflscience.com\/time-travel-the-terminator-and-the-bootstrap-paradox-66337\" target=\"_blank\" rel=\"noopener noreferrer\">possibility<\/a>. However, it is possible to simulate a closed time-loop with quantum mechanics, thanks to the property of entanglement. When two particles are entangled, they are in a single state even if they are separated by huge distances. A change to one is a change to the other, and this happens instantaneously.<\/p>\n<p>So a particle can be prepared for an experiment, entangled, and sent to the experiment. Then scientists can modify its entangled companion, changing the way the particle in the experiment behaves.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hindsight, as they say, is 20\/20, but sometimes it would be nice to have known the outcomes before making a choice.
