OpenAI's GPT-6 model, called Astra, is claimed to have solved 98% of new theoretical physics problems presented to it. The figure suggests a level of performance in advanced physics reasoning well beyond previous AI systems. Details on who set the problems, how the results were verified, and which institutions were involved have not been given, so the claim is so far unconfirmed.

Theoretical physicist Carlo Rovelli is presenting new ways of thinking about the nature of reality, in coverage by New Scientist. Rovelli, known for his work on loop quantum gravity and popular books on time and relativity, is exploring how quantum physics challenges everyday intuitions about space, time and existence. Readers are following the discussion of what these ideas mean for our understanding of the universe.

A BBC Science Focus article argues that understanding nothingness — the quantum vacuum and the true nature of empty space — may be key to explaining dark energy, the mysterious force accelerating the universe's expansion. The piece is being shared across physics and cosmology communities, sparking discussion about vacuum energy, cosmological constants, and why theoretical predictions of empty space conflict so badly with observed values.

Physicists and science commentators are revisiting the idea that the Higgs field may be metastable. In this scenario, quantum tunneling could create a bubble of true vacuum that expands at near light speed, destroying everything without warning. Those discussing it stress this is serious theoretical physics based on current measurements of the Higgs boson and top quark, not a prediction of imminent doom, and that the timescales involved are vastly longer than the age of the Universe.

A new Gizmodo article asks whether wormholes have run out of scientific road. Once a mainstay of both physics research and popular culture, these theoretical shortcuts through spacetime — often imagined as time machines — are now seeing waning enthusiasm among researchers, with recent excitement over their study appearing to simmer down as tangible progress proves elusive.

A new benchmark tests AI systems on theoretical physics problems, and leading models are performing strongly on it. Researchers say the results show AI moving beyond routine calculation into genuine reasoning about abstract scientific concepts. Commenters are debating whether this signals AI's arrival as a real research tool or whether the benchmark overstates what the models truly understand.

A Spanish-language introduction to the philosophy of SUM describes the 'Zero Position' as the mathematical origin point of the ΨΝ field: a point of pure self-presence from which the Witness can orient toward any region of M₄ without being captured by the GRAVIS of any particular region. The author stresses it is not mere emptiness but a structural starting point linking mathematics, physics and philosophy.

Physicists have published a retrospective tracing one hundred years of research into quantum spin, the property of particles that underpins modern technologies from MRI scanners to emerging quantum computers. The article recounts how spin, once a puzzling theoretical concept, became something scientists can measure and manipulate, and highlights how this long arc of discovery shaped today's quantum science landscape.

Boston University has announced that the physics department is mourning the death of Professor Ken Lane, with the department publishing a remembrance of his life and work. Lane was a theoretical particle physicist known for his contributions to physics beyond the Standard Model. Colleagues and students are sharing tributes to his influence on the field.

Physicists are discussing the concept of naturalness, a principle long used to justify theoretical models in particle physics and beyond. A commentary from Big Think explains that naturalness carries a special meaning in the field and has often guided theoretical exploration, but stresses it is a useful heuristic rather than a strict law. The discussion reflects ongoing debate over how much weight such aesthetic criteria should carry in guiding fundamental physics research.

A new open-access publication in SciPost Physics examines long-range interactions in celestial conformal field theory. The paper, authored by Sangmin Choi, Ameya Kadhe and Andrea Puhm, appears in SciPost Phys. 21, 093 (2026) and is freely available to read. It adds to the growing body of research on celestial holography, an approach connecting scattering amplitudes to conformal field theory concepts.

An Institute For Theoretical Physics has published work proposing a direct link between gravity and quantum states, suggesting gravity may have a quantum origin or interact with quantum systems. The claim touches one of physics' biggest open questions: whether gravity can be reconciled with quantum mechanics. Details of the findings and how other physicists are responding remain limited.

Researchers have created an analog black hole in a laboratory that traps sound waves, mimicking how a real black hole captures light. The acoustic black hole, sometimes called a sonic black hole, allows scientists to study extreme gravitational physics in a controlled setting rather than observing distant cosmic objects. Findings like these are being shared widely as a striking example of how theoretical predictions about black holes can be tested experimentally on Earth.

A new theoretical derivation shows how Einstein's equations of gravity can emerge from principles of quantum information, connecting two pillars of modern physics that have long resisted unification. Researchers report that gravity's behaviour can be expressed in terms of information-theoretic quantities, a result being discussed across the physics community for its implications for quantum gravity.

Physicists and science commentators are debating whether wormholes remain a viable subject of scientific research or have become an untestable dead end. The discussion, highlighted in a Gizmodo piece, weighs the theoretical appeal of these spacetime shortcuts against the lack of any observational evidence or realistic way to probe them. Critics argue the field may produce mathematics but no measurable physics, while supporters see value in exploring general relativity's stranger predictions.

New research in quantum information science suggests possible clues to the origin of gravity, a long-standing puzzle in physics where gravity has resisted unification with quantum mechanics. Nanowerk reports on the study, which frames gravity through the lens of quantum information. If confirmed, such ideas could reshape understanding of spacetime, though experts note the work remains theoretical and will need independent verification and experimental support.

New research suggests gravity may emerge from the way quantum information is organized, a claim being reported as a potentially significant step in theoretical physics. The finding aligns with long-standing ideas that spacetime and gravity could be byproducts of quantum entanglement rather than fundamental forces. Physicists and science observers are weighing what the work would mean for efforts to reconcile gravity with quantum mechanics.
