International Society for the Advanced Study of Spacetime



Open questions in spacetime physics and the philosophy of spacetime


Physicists, philosophers of physics, and philosophers are invited to submit what they regard as open or fundamental questions in the area of spacetime physics and the philosophy of spacetime. Short papers providing justification for the submitted open questions are especially welcome. All accepted papers will be posted on this website. Any reactions to these papers are also welcome.

At the 2008 conference we will discuss what has been done to address the identified open questions.

All submissions should be emailed to a member of the Governing Board of the Society:

Craig Callender (University of California, San Diego)
Dennis Dieks (Utrecht University)
Mauro Dorato (University of Rome Three)
John Earman (University of Pittsburgh)
Robert Geroch (University of Chicago) - by regular mail.
Vesselin Petkov (Minkowski Institute)
Steven Savitt (University of British Columbia)
