Dear Colleagues, Here is the essential information about the forthcoming spacetime conference: Conference: Eighth Spacetime Conference https://minkowskiinstitute.com/conferences/2026/ When: September 14-17, 2026 Where: Hotel Sandy Beach in Albena (near Varna), Bulgaria. The place is a guarded resort - arguably the best green, family-friendly Black Sea resort. Organizer: Minkowski Institute Arrival: September 13, 2026 Departure: September 18, 2026 Abstract submission deadline: June 1, 2026 Send abstracts to: 2026conference@minkowskiinstitute.com <mailto:2026conference@minkowskiinstitute.com> Registration deadline: August 1, 2026 Special sessions: "What is the quantum object (the electron, for example) in spacetime?"; for more see the Call for Papers page (https://minkowskiinstitute.com/conferences/2026/call.html) Conference volume: Selected peer-reviewed papers presented at the conference will be published by Minkowski Institute Press, which has published 95 books to date. Scientific Organizing Committee: Valia Allori (University of Bergamo) James Binkoski (Dartmouth College) Carolyn Brighouse (Occidental College, Los Angeles) Karen Crowther (University of Oslo) Erik Curiel (University of Bonn) Robert Geroch (University of Chicago) John B. Manchak (University of California, Irvine) Vesselin Petkov (Minkowski Institute, Montreal) James Read (University of Oxford) Carlo Rovelli (Centre de Physique Théorique de Luminy, Marseille, France) Anguel Stefanov (Bulgarian Academy of Sciences) The Scientific Organizing Committee invites papers from physicists, mathematicians, philosophers of physics and philosophers on any topic related to the nature and ontology of spacetime. We encourage colleagues, who do not plan to give a talk, to attend the conference for two reasons: The panel discussions (at the end of the afternoon sessions) on open questions in spacetime physics have turned out to be very productive exchanges of ideas and insights according to all participants of previous Spacetime Conferences (https://www.minkowskiinstitute.com/conferences/) and Hermann Minkowski Meetings on the Foundations of Spacetime Physics (https://www.minkowskiinstitute.com/meetings/). Special discussion time in the afternoons (after 16:00) is included in the program to stimulate more informal discussions among participants.
