    Scientists have discovered that lead-208, once thought to be spherical, is actually elongated. This challenges nuclear theory and sparks fresh questions about atomic structure and stability. Credit: SciTechDaily.com ==================================================================================== For decades, scientists believed that lead-208, a “doubly magic” and highly stable atomic nucleus, was perfectly spherical. However, groundbreaking new research has shattered this assumption, revealing that its nucleus is actually elongated, much like a rugby ball. By using an advanced gamma-ray spectrometer and high-speed particle collisions, researchers uncovered unexpected quantum behavior that contradicts long-standing nuclear theory. This revelation forces physicists to rethink fundamental principles of nuclear structure, potentially reshaping our...

    The Debrief ^ | March 13, 2025 | Christopher Plain
    A radical new theory suggests that black holes could transition into white holes, creating a location in space where time begins by ejecting material back into the cosmos. The theory also suggests a quantum mechanics link between black and white holes, including an aspect of enigmatic dark matter. The research team behind the new theory believes their work could represent a critical step toward reconciling quantum mechanics and gravity, potentially leading to new theories about the universe’s very nature. Black Holes (and White Holes) Have Long Fascinated Scientists First proposed by Albert Einstein, black holes have long fascinated scientists. Still,...

    A supersolid is a paradox of physics — a material that is both solid and liquid at the same time. This contradictory form of matter was first proposed more than 60 years ago, and, for a long time, people thought it was too nuts to actually exist. But we’re talking about the realm of quantum mechanics, and normal expectations should be thrown out the window. In 2007, researchers at ETH Zurich and MIT unveiled the world’s first supersolids, starting with superflooding sodium and rubidium, respectively. Now, an international team of researchers has unveiled an entirely new route to supersolidity, harnessing...

    Elements heavier than iron are thought to be born in some of the most violent explosions in the cosmos, like the cataclysmic mergers of neutron stars. The coalescence of these ultradense remnants -- which are forged when once-massive stars collapse -- creates superheavy atomic nuclei packed with neutrons in less than a second. In a flash, the jam-packed nucleus seems to go through internal changes and forms elements such as silver and gold.Now, an analysis of the chemical makeup of 42 very old stars scattered in the halo of the Milky Way reveals for the first time that nuclear fission...

    In a remarkable development, researchers have successfully turned light into a supersolid for the first time, paving the way for new insights into the unusual quantum states of matter. This achievement marks a significant milestone in the field of condensed matter physics. Dimitrios Trypogeorgos from Italy’s National Research Council (CNR) reportedly said, “We actually made light into a solid. That’s pretty awesome.” This feat builds on earlier work by fellow CNR scientist Danielle Sanvitto, who demonstrated over a decade ago that light could behave like a fluid. However, Trypogeorgos, Sanvitto, and their team have taken it further by creating what...

    When Isaac Newton inscribed onto parchment his now-famed laws of motion in 1687, he could have only hoped we'd be discussing them three centuries later. Writing in Latin, Newton outlined three universal principles describing how the motion of objects is governed in our Universe, which have been translated, transcribed, discussed and debated at length. But according to a philosopher of language and mathematics, we might have been interpreting Newton's precise wording of his first law of motion slightly wrong all along. Virginia Tech philosopher Daniel Hoek wanted to "set the record straight" after discovering what he describes as a "clumsy...

    American Thinker ^ | 11 Feb, 2025 | Molly Slag
    Unless young students learn the predicate mathematics for calculus, our nation will grind to a halt. While Democrats focus on the liberal arts, which train students to be leftist activists beginning in grade school, it is the STEM studies that keep America functioning. As students ascend that ladder of mathematical logic, calculus becomes central to their ability to maintain our systems and invent new ones. Sadly, though, our schools are failing students, not just in teaching calculus but in teaching everything preceding calculus. It is widely recognized among today’s undergraduates that the STEM field is at once among the most...

    For decades, fusion researchers struggled with neutron isotropy, a key indicator of scalable plasma stability. Zap Energy’s latest results show its FuZE device avoids the pitfalls of past Z pinch failures, generating isotropic neutrons that confirm thermal fusion is occurring. A Major Milestone for Zap’s Fusion Technology In physics, “isotropy” refers to a system where properties remain the same in all directions. In fusion research, neutron energy isotropy is a key measurement that assesses how evenly neutrons are emitted from a device. This uniformity is crucial — when fusion plasmas are isotropic, they indicate a stable, thermal plasma that can...

    Scientists recently reported an unexpected deep-sea development in the Pacific: certain metallic rocks seem to be making oxygen in the dark, without light or sunshine, at the bottom of the ocean. This idea runs counter to the usual belief that oxygen only forms in sunlight through photosynthesis. Although these findings have stirred debate, the central claim is that potato-sized nodules found thousands of feet below the surface appear to split seawater molecules and release oxygen. Oxygen and photosynthesis – the basics Since the late 1700s, we’ve been taught that light creates oxygen through photosynthesis, a crucial natural process that keeps...

    "Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied." Using the James Webb Space Telescope (JWST), astronomers have discovered distant, overly massive supermassive black holes in the early universe. The black holes seem way too massive compared to the mass of the stars in the galaxies that host them. In the modern universe, for galaxies close to our own Milky Way, supermassive black holes tend to have masses equal to around 0.01% of the stellar mass of their host galaxy. Thus, for every 10,000 solar masses attributed to stars...

    In a nutshell: * Astronomers studying the nearby Coma galaxy cluster have found new evidence that the universe is expanding about 9% faster than predicted by our current physics models – a discrepancy known as the Hubble tension. This finding strengthens concerns that our fundamental understanding of cosmic evolution may need revision. * The research team measured precise distances to 13 supernovae within the Coma cluster, determining it lies about 98.5 million light-years from Earth – significantly closer than the 111.8 million light-years predicted by models based on observations of the early universe. This difference is too large to be...
