An AI system has reportedly set a record by independently computing a 9-loop physics amplitude, a Feynman diagram calculation far beyond typical human work. Most real-world perturbative calculations in quantum field theory stop at 2 or 3 loops due to their complexity. The result highlights how machine learning is beginning to automate some of the most demanding mathematical tasks in theoretical physics.

A new physics idea suggests a black hole could shed its 'hair' — the quantum properties that distinguish it — by ejecting them, transforming into a boson star in the process. The concept, reported by ScienceAlert, challenges the classic 'no-hair theorem' that black holes are defined only by mass, charge and spin. Science commentators are sharing the story widely, intrigued by its implications for black hole physics.

Physicists propose that under certain conditions a black hole could shed its 'hair' — quantum fields trapped around it — and transition into a boson star, an exotic object made of particles with no surface or event horizon. The idea, reported by ScienceAlert, touches on the 'no-hair theorem' and could offer new ways to test black hole physics through gravitational wave observations.
