Rethinking Reality without Space and Time

Abstract: This talk explores a Leibnizian/Machian perspective on physics in which space, time, and intrinsic properties are not fundamental, but emergent from an underlying web of relations. Drawing on the framework of Pure Shape Dynamics and the metaphysics of self-subsisting structures, I will argue that physical reality can be fully described without appealing to external backgrounds or absolute quantities. Instead, what persists are evolving patterns of relational quantities that together form a coherent, self-contained structure. This shift not only reframes familiar concepts like identity, locality, and entanglement, but also invites us to reconsider the ontological status of temporality itself as a product of internal perspective within an undivided whole.

Speaker bio: Antonio Vassallo is Assistant Professor at the Warsaw University of Technology. His research lies at the intersection of philosophy and fundamental physics, with a focus on relational approaches to space, time, and quantum theory. He holds a MSc in physics from the University of Catania and a PhD in philosophy from the Universities of Lausanne and Warsaw. He has held research positions in Switzerland, Spain, and Poland. Among his publications is the edited volume "The Foundations of Spacetime Physics: Philosophical Perspectives" (Routledge, 2022).

Moderator: This talk is moderated by Ted Theodosopoulos. Ted is a mathematician who, after working for years in academia and industry, transitioned to teaching at the pre-college level sixteen years ago, the last eight at Nueva, where he teaches math and economics. Ted’s research background is in the area of interacting stochastic systems, with particular applications in biology and economics.

Relatorium seminar

Series comments: The name "Relatorium" combines "relator" with the Latin root "-ium," meaning "a place for activities" (as in "auditorium" or "gymnasium"). This seminar series is a platform to relate ideas, interact with math, and connect with each other.

In this series, we explore math beyond what we usually hear in standard talks. These sessions fall somewhere between a technical talk and a podcast: moderately formal, yet conversational. The philosophy behind the series is that math is best learned by active participation rather than passive listening. Our aim is to “engage and involve,” inviting everyone to think actively with the speaker. The concepts are accessible, exploratory, and intended to spark questions and discussions.

The idea of relatability has strong ties to compassion — creating space for shared understanding and exploration - which is the spirit of this seminar! This is a pilot project, so we’re here to improvise, learn, and evolve as we go!
