Curiel talk this Thursday!

• Thursday 30 April 2020 at Geneva at 16:15 (14:15 UTC) – Erik Curiel (LMU Munich): On the mathematical, physical, and conceptual cogency of quantum field theory on curved spacetime

Quantum field theory on curved spacetime (QFT-CST) is the framework within which our current theories about quantum effects around black holes are formulated.  The results of their study, including most famously the Hawking effect and its infamous spawn the information-loss paradox, have revealed several surprises that threaten to overturn the views of space, time, and matter that general relativity and quantum field theory each on their own suggests.  In partiular, they appear to point to a deep and hitherto unsuspected connection among our three most fundamental theories, general relativity, quantum field theory and thermodynamics.  As such, work in QFT-CST provides some of the most important, central, and fruitful fields of study in theoretical physics, bringing together workers from a variety of fields such as cosmology, general relativity, quantum field theory, particle physics, fluid dynamics, condensed matter, and quantum gravity, providing bridges that now closely connect disciplines once seen as largely independent.  The framework, however, has serious mathematical, physical and conceptual problems.  In this talk, I will provide a sketch of the framework and a survey of some of the most important problems it faces.

In terms of technical difficulty, this talk rates 4/5 4.

The meeting is open to all and will be held over ZOOM (, with the meeting ID 286-342-072. This will be the meeting ID for all our Thursday seminars this semester. In order to directly join, please use
We will record this meeting, and plan to livestream it on our Youtube channel ‘Beyond Spacetime:
Anyone is welcome to participate!

PhD Fellowship at UIC

Our new Templeton grant will make possible a modest additional fellowship for PhD students admitted to UIC as Teaching Assistants to pursue philosophy of physics.

“A two-year top-up fellowship of $2,500/year is available for a suitable student admitted with a TAship. The student would have demonstrated interest and ability in philosophy of physics, and working with the Beyond Spacetime group under the direction of Professor Nick Huggett. No special application is required, but the application should address qualification to pursue philosophy  of physics, and suitable candidates will be interviewed by Professor Huggett before a decision is reached”

Please pass this on to any undergraduates considering where to apply for graduate school for philosophy of physics.

Information on applying to UIC is found here:

Visitor program at UIC

The funded visitor program is closed for now – we will re-advertise here when it starts again.

We invite interested scholars for short visits to the Cosmology Beyond Spacetime research group located in the philosophy department at the University of Illinois at Chicago in Spring 2020. 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).

We hope to have range of visitors: faculty and graduate students; general philosophers, philosophers of physics, and physicists; those sharing their expertise, and those learning about the philosophy of quantum gravity and the work of our group and speakers. Visitors will help us inform the philosophical and physics communities about philosophical issues in quantum gravity; and they will help us learn more about these philosophical dimensions though our interactions. While visitors will be credentialed philosophers or physicists, in some cases a credible interest in professional engagement with the group will be more important than prior work in quantum gravity.

In the first instance, potential visitors are requested to send a brief (one page) letter of interest, explaining their current academic status, research focus, and interest in our project. Please also explain any special activities you would like to undertake with the group, date(s) you would like to visit, and estimated cost of a flight. We will request further information as needed, and discuss times and budgets (up to $500, with the possibility of more for longer visits, depending on demand) with successful applicants.

We especially encourage applications from women and underrepresented minorities.

Review of requests will be ongoing.

Send letters of interest to And please share the invitation.

Talk Next Week: Fedele Lizzi

• Wednesday 16 October 2019 at UIC at 11 am – Fedele Lizzi (Napoli): Pointless Physics

Abstract: I will describe the role of points in modern physics, and in particular in the attempts to built a theory of quantum gravity. Modern theories will require a quantum spacetime, and in it the usual concept of point, as we have used so far, may lose its meaning. In particular I will discuss noncommutative geometry, a branch born to describe the quantum space of velocity and momenta, and how it could be useful in quantum gravity. In terms of technical difficulty, this talk rates 3/5 3.

New Templeton Grant Awarded

The Beyond Spacetime project of Nick Huggett (Illinois-Chicago) and Christian Wüthrich (Geneva) announces the award of a $600K grant from the John Templeton Foundation, to support their work on the project “Cosmology Beyond Spacetime”. Activities will include pre- and post-doctoral fellowships, speaker series, meetings, and publications. Follow the project on, where some activities are already advertised; more information will follow soon.

Beyond Spacetime at Pitt 2020-21

The Center for Philosophy of Science at the University of Pittsburgh invites applications for Fellowships supporting visits in the Center for a term or an academic year during the year 2020-2021.  For details, visit the Center Website, and see:
