Lee's Fest: Quantum Gravity and the Nature of Time

What is time? Is it fundamental or emergent? This question lies at the foundation of contemporary physics and provides a key to unlocking some of its most challenging open problems, from quantum gravity to cosmology. The quest to understand time extends beyond the realm of physics, providing a privileged standpoint to address questions in diverse fields such as philosophy, mathematics, and computer science.   In this conference, we explore the nature of time from many different perspectives. This is the occasion to honor Perimeter’s “Master of Time,” Lee Smolin, and to celebrate his seminal scientific contributions. Lee Smolin is a founding faculty member of Perimeter Institute and a primary inspiration behind its spirit and design. This is an opportunity to journey back in time to the origins of some of the groundbreaking initiatives that Lee helped develop, and to look forward to future developments inspired by his achievements. The conference focuses on time but also on the foundations of quantum mechanics and the quest for quantum gravity, particularly Loop Quantum Gravity, of which Lee Smolin is a co-creator. In the spirit of Lee Smolin, the conference celebrates the interdisciplinary nature of the journey toward quantum gravity, with contributions from physics, mathematics, computer science, and philosophy.     Registration Registration for In Person Participants closes on 14 May 2025, Apply Registration for Virtual Participants closes on 2 June 2025, Apply   Call for Abstracts Abstracts submissions closes on 28 March 2025, Submit Submission can be in the form of: • Contributed Talks will be 10 mins long (includes Q&A) • Poster Session If you have questions about the Call for Abstracts, please contact [email protected]     :: :: :: Scientific Organizers Laurent Freidel (Perimeter Institute) Maïté Dupuis (Perimeter Institute) Dongxue Qu (Perimeter Institute) Francesca Vidotto (Western University)
