Scientists are prepping an experiment to see if we can observe retrocausality; where an action in the present affects the past.
Sounds crazy right? Well when you get down to the quantum scale, when reality is broken up in to quanta, or chunks like electrons or wave forms, things get very weird. Real temporal order is not important at this scale, and time can “move” backwards as well as forwards.
This is not going to mean we’ll be able to travel back in time, but it might help us to better understand the nature of time.
