Physicists report new evidence that gravity can collapse the dimensions of space, supporting the idea that gravity is holographic — that the universe's three-dimensional structure may be encoded on a lower-dimensional surface. Researchers stress the implications are not yet understood, and what this means for the nature of reality remains an open question driving discussion among cosmologists and science commentators.

A study using artificial intelligence at the Large Hadron Collider is challenging the theory that the universe may contain ten dimensions. Researchers applied machine learning methods to collider data to test predictions tied to string theory, and the results reportedly cast doubt on whether the extra dimensions theorised by physicists actually exist, prompting debate in the physics community.

Researchers subjected water to light roughly 10 billion times brighter than sunlight, expecting faster evaporation, but the water did not evaporate any quicker. The surprising null result challenges assumptions about how extremely intense light interacts with liquid water, and is drawing attention from physicists curious about what limits evaporation under such extreme conditions.

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.

Reports say the disconnection of the Large Hadron Collider has begun, marking the start of a shutdown phase for the world's largest particle accelerator at CERN near Geneva. The machine, famous for discovering the Higgs boson in 2012, is periodically switched off for maintenance and upgrades between experimental runs. Readers and physicists are following news of the work, with attention on what upgrades could mean for future discoveries.

Researchers have used a quantum simulator to observe a process capable of breaking quark strings, the bonds that bind quarks together inside particles. The simulation offers a rare window into string-breaking, a phenomenon in quantum chromodynamics that is otherwise impossible to track directly because quarks cannot be isolated. Physicists say such simulators could help probe questions that classical computers cannot handle.

Anthropic claims its Claude AI model computed a nine-loop particle physics amplitude, an extraordinarily complex calculation in quantum field theory that would normally demand enormous effort from human physicists. If verified, the result would mark a striking demonstration of AI capabilities in theoretical physics, and it is prompting debate among researchers about how the computation was performed and whether it can be independently confirmed.

Claude, the AI assistant developed by Anthropic, is claimed to have beaten a record associated with physicist Lance Dixon by computing a nine-loop physics amplitude. The claim suggests a major step for artificial intelligence in theoretical physics, where multi-loop amplitudes describe particle interactions and are notoriously hard to calculate.
