Becoming Present: The Collapse of Possibility into Time

Modern physics has increasingly highlighted the special role of the present moment in the unfolding of reality. Quantum experiments suggest that reality is not a static four-dimensional block but is actively determined in the present moment, as measurements seem to bring about definite outcomes only at the instant they are performed. This resonates with presentist intuitions (the view that only the present exists), yet strict presentism faces serious metaphysical problems. How can only the present be real, if past causes clearly leave effects and future events are anticipated? This paper advocates Existential Realism (ER) as a superior ontological framework that preserves the primacy of the present while accounting for the reality of past causes and future possibilities. Building on our earlier introduction of ER and critique of presentism’s limits, we will show that ER provides a richer ontology for quantum phenomena – one that distinguishes between existence and reality, and accommodates genuine becoming and temporal agency in ways that purely present-based theories cannot. We make bold but rigorous claims: that quantum mechanics “prefers” a present-centered ontology, and that Existential Realism best captures this without the pitfalls of naive presentism or the stagnancy of eternalism. In short, ER not only aligns with quantum physics – it elevates and refines the very notion of what it means for something to be real in time.
