FQxI @fqxi.org · 02/10/2026In 2007, FQxI member Garrett Lisi offered $100 to anyone who could find three sign errors in his online physics notes. There were no takers until recently, when an AI agent emailed. He tells the story on QSpace News: qspace.fqxi.org/news/165333/... 040
FQxI @fqxi.org · 29/09/2026FQxI members Vlatko Vedral and Roger Penrose are among authors of an experiment that has made the first direct measurement of the quantum phase of a freely falling object. 130
FQxI @fqxi.org · 26/09/2026We've set a guest challenge at the Moth Hack: make something that teaches a general audience about quantum computing or quantum mechanics, using one of Moth's Atlas Engines. The winner gets a £150 voucher. Entries are open online until 2 October. 130
FQxI @fqxi.org · 24/09/2026Is gravity quantum? It's one of the big open questions in physics. The Bose-Marletto-Vedral experiment, proposed by Chiara Marletto, Vlatko Vedral and colleagues, would test whether gravity alone can entangle two tiny masses. 220
FQxI @fqxi.org · 22/09/2026You leave a cat alone with physicists for five minutes... New research puts gravity’s role in quantum decoherence to the test. qspace.fqxi.org/news/165329/... 021
FQxI @fqxi.org · 18/09/2026Is life really quantum? Gerard McCaul pushes back. Full interview: www.youtube.com/watch?v=7xba... 100
FQxI @fqxi.org · 14/09/2026With recent AI safety concerns making headlines, Susan Schneider’s interview with The Sun feels especially timely: could AI become conscious? Read more: qspace.fqxi.org/news/165327/... 120
FQxI @fqxi.org · 04/09/2026What happens if the universe is infinite? A quick thought experiment with physicist Anthony Aguirre. 100
FQxI @fqxi.org · 01/09/2026Science needs people who can afford to be wrong. Yet we seem to have built a career ladder that removes them. [VISUAL THREAD] 161
FQxI @fqxi.org · 25/08/2026@nafshordi.bsky.social and Phil Halper surveyed 1,675 physicists on ten of the big unanswered questions. Ghazal Geshnizjani and @seanmcarroll.bsky.social joined them to go through the results. 161
FQxI @fqxi.org · 21/08/2026Jordan Scharnhorst is one of our new FQxI Fellows. He’s joining us for Foundational Answers, a programme taking stock of progress on 10 major topics in foundational science and identifying the questions still open. A part of that work is adversarial collaboration. Jordan explains what that means. 001
FQxI @fqxi.org · 11/08/2026There’s a total solar eclipse on August 12! The Sun will be completely covered in Greenland, Iceland, northern Russia and parts of Spain, with a partial eclipse visible across a much wider area. It’s also the day of a six-planet morning lineup and the peak of the Perseid meteor shower. VIA: NASA 030
FQxI @fqxi.org · 07/08/2026Some physicists believe that the future can influence the past. For someone hearing that for the first time... it sounds pretty crazy. We spoke briefly to Matthew Leifer about how that can possibly be true! 021
FQxI @fqxi.org · 30/07/20261/4 How do you escape the "parallel universe of fake papers?" @nicolakimjones.bsky.social spoke with Ilka Agricola, chair of the IMU's committee on publishing and a physicist and mathematician at the University of Marburg, in Germany. Full story: qspace.fqxi.org/articles/281... 100
FQxI @fqxi.org · 27/07/2026Meet our new Foundational Fellows: Jordan Scharnhost, Caroline Jones, Nuriya Nurgalieva, Lucy James, Jennifer Rittenhouse, Joseph Schindler 120
FQxI @fqxi.org · 23/07/2026A corridor chat with Chris Smeenk, professor at @westernu.ca, about correcting common misunderstandings about the Big Bang and the early universe. Chris' research centres around the scientific method and the nature of our knowledge of physics. 021
FQxI @fqxi.org · 20/07/2026A word from our cofounder Anthony Aguirre on the Foundational Answers Workshop at Broughton Hall, the launch of a new FQxI program exploring what 20 years of asking the big questions in physics and cosmology have actually taught us. Keep your eyes peeled for more soon! 010
FQxI @fqxi.org · 17/07/2026The levels in this horror game are generated on a real quantum computer. We asked Moth's chief scientist, @decodoku.bsky.social, how that works. Find out how it works: qspace.fqxi.org/news/165325/... 010
