The videos of our conference, which was held near Geneva 27-30 June 2017, are now available on our YouTube channel on their separate playlist:
Please consider entering our essay contest – winners receive $1000 and an invitation to speak. We will consider original work on the philosophical foundations of quantum gravity (including metaphysical issues arising in connection with such theories). Deadline: 9/15/17
Full details are above, or here: https://beyondspacetime.net/2017-essay-prize-contest/
We invite interested scholars for short visits to the Spacetime After Quantum Gravity research group, located in the philosophy departments at the University of Illinois at Chicago and the University of Geneva. To facilitate visits we can offer financial assistance for travel and lodging, office facilities, and of course excellent intellectual company. Visits can be from a few days to a few weeks (or possibly longer).
Details are here: https://beyondspacetime.net/space-and-time-after-quantum-gravity/visit-us/
Most of the videos from the Spring semester are now available: most recently from Tiziana Vistarini, Tim Palmer, and Karim Thébault (see here). The remaining ones are coming soon! Enjoy.
Please join us this week for the final talk of the year – in Chicago at 11am in UH1430, on skype in Geneva, or on YouTube.
• Wednesday 31 May 2017 at UIC – Nic Teh (Notre Dame): Newton-Cartan theory and Emergent Newtonian Gravitation
• Wednesday 24 May 2017 at Geneva – Samuel Fletcher (Minnesota): Reduction, emergence, and direct limits
Abstract: Most discussions of spacetime emergence and the “physical salience” of the structures employed in theories of quantum gravity have understood these terms informally. Applying some new formal definitions based on “similarity structure” on models of theories, I show how to make more precise the sense in which a physical continuum of events could be emergent, and to connect the discussion of physical salience with a precise definition of intertheoretic reduction. As a test example, I consider claims about the emergence of the continuum of relativistic spacetime from direct limits of causal set histories, showing how their justification, though presently incomplete, could be completed. Time permitting, I will comment on the relation between this approach and causal set theory’s hauptvermutung. In terms of technical difficulty, this talk rates 4/5

We’re very happy to announce our two prize winners of the 2016-17 essay prize – we make the papers available on the philsci archive when they are ready.
• Suddhasattwa Brahma (Fudan): Emergence of time in Loop Quantum Gravity
• Sebastian De Haro (Amsterdam/Cambridge): Spacetime and Physical Equivalence
We have two talks at UIC next week:
Wednesday 3 May 2017 11am – Laura Ruetsche (Michigan): Renormalization Group Realism: An Unduly Skeptical Review
Thursday 4 May 2017 at UIC 9am – Michael Miller (Pittsburgh): Three obstacles to the interpretation of quantum field theory
Abstracts are available above – as are details of the locations. We will livestream to Geneva, and hopefully to YouTube. Please join us!
We are pleased to announce our third essay contest, for papers from philosophers or physicists that address issues in the philosophical foundations of quantum gravity. Full details here: https://beyondspacetime.net/2017-essay-prize-contest/ (and above). The winners will receive $1000, a visit to UIC or Geneva, and publication in the anthology that we are editing. Women and minorities are encouraged to submit – and we emphasize that the scope of the contest includes metaphysical investigations of the subject. Deadline: September 15th, 2017
