"A trio of physicists is proposing a new direction for understanding the concept of time.....describe their new ideas beginning with the suggestion that initial conditions don't necessarily need to be imposed on time-symmetric law when attempting to describe solutions to behaviors that define an "arrow of time."
For all the advances made in understanding the world around us, there are still two very basic fundamental concepts that have defied explanation: time and gravity.
It is widely believed that special initial conditions must be imposed on any time-symmetric law if its solutions are to exhibit behavior of any kind that defines an "arrow of time." We show that this is not so.
The simplest nontrivial time-symmetric law that can be used to model a dynamically closed universe
is the Newtonian N-body problem with vanishing total energy and angular momentum. Because of special properties of this system (likely to be shared by any law of the Universe), its typical solutions all divide at a uniquely defined point into two halves. In each, a well-defined measure of shape complexity fluctuates but grows irreversibly between rising bounds from that point. Structures that store dynamical information are created as the complexity grows and act as "records." Each solution can be viewed as having a single past and two distinct futures emerging from it. Any internal observer must be in one half of the solution and will only be aware of the records of one branch and deduce a unique past and future direction from inspection of the available records."

Could a "single past" followed by 2 "distinct futures" be the result of choices we make as it relates to our future? That being a result of free will?
