When the Future and the Past Decide Together

The scientific article “A Causal Symmetry Approach to Quantum Nonlocality and Information” by Dr. Elias Rubenstein questions the usual way quantum physics is presented, in which an experiment is considered only from its initial state. Many people have heard of quantum physics, mostly in connection with randomness and “spooky” long-distance effects between particles. This paper asks a simple but far-reaching question: What if an event in the quantum world is not only determined by the past, but also co-shaped by the future? Instead of saying, “The past pushes the present forward,” it explores whether past and future together form the frame within which an event unfolds.

In the usual picture, you know how the experiment is prepared, you calculate probabilities, and you accept that the outcome is random. In Dr. Rubenstein’s approach, the actual final state is also taken into account. The beginning and the end are treated like two fixed points, with the process fitting in between. The apparent randomness then arises mainly from the fact that we are missing part of the relevant information. We see only the beginning and the outcome, but not the full informational structure that connects them.

The paper shows that this idea can be captured precisely in terms of information. It describes how one can measure how strongly the beginning and the end of a process are linked in terms of information. From this perspective, quantum entanglement no longer appears as an inexplicable miracle, but as an indication that information is not only local and not only organized “one-way forward.” At the same time, it still remains impossible to send messages back into the past; the approach therefore does not change the observable causal structure of everyday life, but the deeper description of how things hang together.

The relevance of this paper lies in the bridge it builds: it connects quantum phenomena, which are often seen as completely abstract, with a simple picture of past, future, and information. It proposes a way to test this view experimentally, for example using special quantum random number generators. In this way, an idea that sounds philosophical becomes a scientifically testable approach: the work invites us to see quantum physics not as groundless randomness, but as an ordered process whose informational structure we are only gradually uncovering.
