There is an argument among physicists over whether that cloud of maybes represents something real, or if it’s just a convenient representation.

A physicist by the name of Huw Price claimed back in 2012 that if the strange probabilities behind quantum states reflect something real, and if nothing restricts time to one direction, the black ball in that cloud of maybes could theoretically roll out of the pocket and knock the white ball.

„Critics object that there is complete time-symmetry in classical physics, and yet no apparent retrocausality. Why should the quantum world be any different?” Price wrote, paraphrasing the thoughts of most physicists.

Matthew S. Leifer from Chapman University in California and Matthew F. Pusey from the Perimeter Institute for Theoretical Physics in Ontario also wondered if the quantum world might be different when it comes to time.

The pair exchanged some of Price’s assumptions and applied their new model to something called Bell’s theorem, which is a big deal in this whole spooky action at a distance business.
