The Eighth Spacetime Conference, organized by Minkowski Institute (Montreal), will be held in Hotel Sandy Beach in Albena (near Varna), Bulgaria, which is a guarded resort – arguably the best green, family-friendly Black Sea resort.

The scientific organizing committee invites papers from physicists, mathematicians and philosophers of physics on any topic related to the nature and ontology of spacetime. There will be a number of special sessions, including on “What is the quantum object (the electron, for example) in spacetime?”

Extended abstracts of between one and two pages should be e-mailed to 2026conference@minkowskiinstitute.com by June 1, 2026. Submissions will be reviewed and notification of acceptance will be sent by June 15, 2026.
