FQxI has catalyzed much-needed dialogue between disciplines that rarely engage in an intellectual discourse; such connections have already enabled path-breaking research and could drive future paradigm shifts…FQxI remains almost unique in this space.

FQxI is an important part of the fundamental physics community, especially regarding expanding the boundaries of what questions can be addressed.

Closer To Truth
FQxI advances human knowledge as no other organization on earth, daring to gaze with a sharp eye and an open mind over the horizon in physics and cosmology, yet always maintaining highest standards of scientific analysis and integrity.
Closer To Truth (CTT) is proud to have a long relationship with FQxI. Beginning in 2007, CTT has filmed several hundred interviews at FQxI conferences and created over 20 FQxI-derived TV episodes that are broadcast on PBS/public television stations, Closer To Truth website and Closer To Truth YouTube channel. Core topics include: cosmology, multiverse, beginning(s) of the universe, end of the universe, time, information, quantum theory and the observer, even consciousness. Views are in the low millions. FQxI addresses the big questions of existence and fundamental reality, questions that have no boundaries and reflect our common humanity, today needed more than ever.

FQxI grants have given me the “excuse” I needed to justify working on topics I am passionate about and have given me a valuable lifeline before obtaining a permanent position. I probably would no longer be in academia were it not for FQxI.

FQxI is a fundamental resource in the landscape of contemporary intellectual work in science. Thank you FQxI!
I think that FQxI, it’s a fundamental resource in the landscape of contemporary intellectual work in science. A lot of scientific research today, the very large majority of it, it’s in one way or another oriented toward the technical, or practical, or useful applications, which is very good, but it misses a deep reflection of the foundations. There are very few supporting structures for bringing together the thinkers that think about the depth of the foundations of our current understanding of reality on the basis of what science tells us and I think FQxI is one of the very few, if not almost the unique one that plays this role. I’m extremely grateful that for what it has provided for me, in terms of connection with other people, in terms of resources for doing things, in terms of the fantastic ideas that I’ve seen there developed, taken seriously, discussed, abandoned, or sometimes brought to success. Thank you FQxI!

It’s hard to express the difference FQxI’s made–that you nurture and value work on expansive, risky topics. I think it gives courage to a lot of people.

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.
