Can the Future Influence the Past?

Emily Adlam (Western University)

Recently there has been a resurgence of interest in `retrocausal’ approaches to quantum mechanics, which say that the future can sometimes influence the past. In this talk, I will explain why some physicists believe that the future can influence the past. I’ll discuss two different types of retrocausal models and explain their connection to time travel and the grandfather paradox, and then I will describe what these results mean for quantum mechanics.
