Setting Time Aright
This conference will bring together leading researchers across a wide range of fields within physics and cosmology, as well as from computer science, complex systems, biology, philosophy, and psychology. The participants will discuss a number of interrelated foundational questions related to the nature of time, such as:
Questions Include:
- How does time “flow”?
- Why does time have a direction?
- How does the universe evolve?
- What does it mean to record a memory?
- What does it mean to perform a computation?
- What happens as we think?
- How does complexity emerge?
- How do organisms age?
- How do species and genomes evolve?

PressRelease: Precision experiment puts pressure on quantum collapse theories
Quantum mechanics, the theory governing the microscopic world, is famously counterintuitive. A particle can exist in a superposition of multiple states, such as different positions, until a measurement is performed. At that point, the wavefunction describing that particle appears to ‘collapse’ to a single outcome. This puzzle lies at the heart of the measurement problem, famously illustrated by Schrödinger’s cat, suspended between life and death until observed. The XENONnT detector, which was designed to be sensitive to rare physics events, has tightened constraints on one family of possible solutions to the measurement problem, known as ‘collapse theories.’ The work, which was partially funded by FQxI, was reported in Physical Review Letters in March 2026.
