Sean Carroll, a theoretical physicist at Caltech, answers questions about his theory of time at the annual meeting of the American Association for the Advancement of Science. Among other ideas, he believes that our universe is one of many, and that the Arrow of Time exists because our universe moves away from a static, entropy-free universe at the center of this bigger multiverse. When asked if time travel is possible, Carrol said, “The simplest way out of the puzzle of time travel is to say that it can’t be done. That’s very likely the right answer. However, we don’t know for sure. We’re not absolutely proving that it can’t be done.” He added that, “You can easily go to the future, that’s not a problem… Yesterday, I went to the future and here I am!”
