Physicists at UC Santa Barbara have extended the search for evidence of microscopic black holes produced at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN). The formation of these tiny, fleeting objects at the LHC represents one way theorists have sought to resolve anomalies in our understanding of the basic structure of spacetime, while the method used to look for them demonstrates a new way of searching for new particles. https://phys.org/news/2026-09-physicists-quantum-black-holes-lhc.html General Physics Fri, 18 Sep 2026 14:20:07 EDT news708954181 Magnetic reconnection is a process that occurs when the magnetic fields of a conductive plasma quickly rearrange and release massive amounts of stored magnetic energy. It is widely thought to be the underlying mechanism behind cosmic events such as solar flares and substorms in Earth's magnetosphere. https://phys.org/news/2026-09-laser-recreate-solar-flare-physics.html General Physics Fri, 18 Sep 2026 13:40:01 EDT news708949682 Somewhere between the microscopic realm of elementary particles and the macroscopic world of human beings, something strange happens: The rules of quantum physics, which work so exquisitely for tiny atoms, seem to lose their grip as objects grow larger. Pondering where and how this shift from small-scale quantum fuzziness to everyday sharp certainty happens gives rise to thought-experiment oddities like Schrödinger's famous dead-and-alive cat. The process by which quantum phenomena like superposition—the paradoxical affliction of Schrödinger's cat—fade into the classical reality we experience is known as decoherence. https://phys.org/news/2026-09-schrdinger-cat-underground-gravity-quantum.html General Physics Thu, 17 Sep 2026 15:00:11 EDT news708864241 Dark matter is one of the oldest open problems in physics. It makes up most of the matter in the universe and shapes how galaxies form and move, yet no one has ever directly detected it. Physicists have proposed dozens of candidates to explain it: exotic new particles, black holes formed moments after the Big Bang and more. https://phys.org/news/2026-09-dark-natural-physicist.html General Physics Thu, 17 Sep 2026 10:10:01 EDT news708856482 In March 2026, scientists succeeded in transporting antiprotons by road for the first time in a purpose-built trap loaded on a truck. The BASE collaboration, which realized this experiment at the European Organization for Nuclear Research (CERN) in Geneva under the lead of Professor Dr Stefan Ulmer and Dr Christian Smorra from Heinrich Heine University Düsseldorf (HHU), now presents its findings and experiences from this pioneering experiment in the journal Nature. Among other things, they report that it was possible to store antiprotons in a mobile transport vessel for more than a month for the first time ever. https://phys.org/news/2026-09-mobile-antiprotons-road-month-world.html General Physics Wed, 16 Sep 2026 18:30:06 EDT news708792361 When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, they play an important role in hydraulic engineering. Understanding unsteady flows like roll waves is crucial for the design, management and safety of hydraulic structures such as dam spillway chutes. https://phys.org/news/2026-09-emerge-uniform-destabilizes-steep-slopes.html General Physics Wed, 16 Sep 2026 17:00:06 EDT news708783841 Some track cyclists appear to break the rules of physics, but a new study, published in the journal Royal Society Open Science, has created a model explaining the illusion. The results suggest that a quick succession of well-timed moves can help cyclists get a head start without actually breaking the rules of the race or the rules of physics. https://phys.org/news/2026-09-cyclists-paradoxically-rest-velocity.html General Physics Wed, 16 Sep 2026 11:10:01 EDT news708775117 Through joint research with the U.S. Geological Survey and the University of Tokyo, NIMS for the first time experimentally demonstrated friction completely independent of sliding velocity—an ideal that had never been realized—by heating mica, a layered oxide also used as a lubricant material, to 200°C (392°F). NIMS also clarified that this is caused by the disappearance of defects within crystals at high temperatures. https://phys.org/news/2026-09-mica-200c-reveals-friction-independent.html General Physics Wed, 16 Sep 2026 09:20:03 EDT news708766442 Does gravity act equally on all particles in the universe, or are there differences between ordinary and exotic matter? Physics professor Anna Soter and her team at ETH Zurich and the Paul Scherrer Institute (PSI) in Villigen are investigating this question. "We have taken an important step toward carrying out an exciting experiment on this topic," says Soter.

However, some of these elements also emit X-rays in the same energy range as the gamma-ray emissions, masking the signal and making nuclear stockpiles harder to assess. https://phys.org/news/2026-09-ultra-cold-quantum-sensors-ray.html General Physics Thu, 10 Sep 2026 19:00:01 EDT news708269641 Quantum technologies are poised to transform fields ranging from medicine and sensing to computing and communications by manipulating the energy states of atoms and molecules.

Although its gravitational influence shapes galaxies and the large-scale structure of the cosmos, dark matter has never been directly detected. Now, an international team has identified a new class of quantum materials that could dramatically improve the search for some of the lightest and most elusive forms of dark matter. https://phys.org/news/2026-09-unconventional-quantum-materials-boost-dark.html General Physics Wed, 09 Sep 2026 19:20:04 EDT news708186498 We have all seen something suddenly break: a phone screen cracks, a plastic object snaps or a piece of glass shatters. To our eyes, the failure seems to happen all at once.

A cooling cup of coffee may not seem particularly thoughtful. At the scale of a kitchen, heat appears to follow a straightforward rule: it moves from warmer places to cooler ones. Leave the cup unattended long enough, and the disappointing result offers convincing evidence that this rule works. https://phys.org/news/2026-09-memory-theoretical-framework-track.html General Physics Thu, 03 Sep 2026 10:00:08 EDT news707644802 An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result shows that a fundamental principle at the heart of Einstein's theory of gravity remains consistent with the behavior of matter in the quantum world. The study, led by Ben-Gurion University of the Negev, the University of Ulm and the University of Oxford, was published today (Sept. 2) in Science Advances. https://phys.org/news/2026-09-scientists-einstein-gravity-quantum-world.html General Physics Wed, 02 Sep 2026 14:00:13 EDT news707475782 The weak equivalence principle (WEP) is central to Einstein's general relativity.
