  • New theory reveals the shape of a single photon

    A new theory, that explains how light and matter interact at the quantum level has enabled researchers to define the precise shape of a single photon. Research at the University of Birmingham, published in Physical Review Letters, explores the nature of photons (individual particles of light) in unprecedented detail to show how they are emitted by atoms or molecules and shaped by their environment. The nature of this interaction leads to infinite possibilities for light to exist and propagate, or travel, through its surrounding environment. This limitless possibility, however, makes the interactions exceptionally hard to model, and is a challenge...

    The James Webb Space Telescope has found evidence of large, bright galaxies in the early universe, challenging traditional dark matter theories and suggesting a rapid galactic formation as predicted by MOND. Credit: SciTechDaily.com New findings from the James Webb Space Telescope contradict traditional theories about early galaxy formation, revealing large and bright galaxies instead of the expected small, dim structures. This observation supports the Modified Newtonian Dynamics (MOND) theory, which disputes the role of dark matter and suggests a rapid formation of galaxies in the early universe, presenting a challenge to the widely accepted dark matter hypothesis. Challenging Conventional Galaxy...

    Dark matter could be the result of fermions pushed into a warped fifth dimension. This theory builds on an idea first stated in 1999, but is unique in its findings. Dark matter makes up 75 percent of matter but has never been observed ... yet. Scientists say they can explain dark matter by positing a particle that links to a fifth dimension. While the “warped extra dimension” (WED) is a trademark of a popular physics model first introduced in 1999, this research, published in The European Physical Journal C, is the first to cohesively use the theory to explain the...

Scientists are now closer than ever to bridging the gap between imagination and reality in this cutting-edge field.
  • Oops! Newly Discovered Infinities Might Have Broken The Mathematical Universe..."This changes completely the landscape of large cardinals."

    IFL Science ^ | December 19, 2024 | Dr. Katie Spalding
    It’s an idea straight out of the schoolyard: that you might one day accidentally count so high that you break the laws of math. A new preprint (that has not yet been peer-reviewed) seems to have done just that, however – and it could have huge ramifications for how we ought to understand infinity. It’s fitting that such a baffling result would have come from set theory: it’s an area with a reputation for being abstract and often counter-intuitive; it has its own esoteric alphabet and language; and it’s famous for results that seem either too basic to have even...

    The M87 Galaxy, as seen via the Hubble Space Telescope (NASA/Hubble). For the first time in a decade, the black hole at the center of the M87 galaxy has erupted in an enormous gamma-ray flare, a rare and significant event that defied expectations in the latest analysis by astrophysicists. Several large collaborations, including the Event Horizon Telescope (EHT), as well as the Fermi Gamma Ray Space Telescope, and the MAGIC, VERITAS, HESS, and EAVN telescopes pooled their resources to observe the massive cosmic event, detailed in a new paper published in Astronomy and Astrophysics. M87 Black Hole Messier 87 is...

    Scientists report the first known observation of a variety of quasiparticle that exhibits a very peculiar behavior: it appears to have mass, but only while moving in one direction. Scientists at Pennsylvania State University recently succeeded in detecting the unusual quasiparticle while conducting studies involving a semi-metallic crystalline material. Known as a semi-Dirac fermion, this unique formation of particles was first theorized more than a decade ago, but until now had never been directly observed. The discovery potentially paves the way toward future advances in a range of emerging technologies that include power storage and novel forms of sensor technologies....

    Astronomers using the James Webb Space Telescope to peer back in time into the farthest reaches of the universe have found stunning evidence for an alternate theory of gravity. Current models of galaxy formation in the early cosmos predict the presence of excess gravity caused by dark matter to pull material into slowly forming galaxies. However, an alternate theory of gravity first proposed in 1998 called Modified Newtonian Dynamics (MOND) suggests that structures in the early universe formed very quickly without the need for theoretical dark matter. Now, researchers from Case Western Reserve University say that scans of ancient galaxies...

    The James Webb Space Telescope (Credit: NASA) The James Webb Space Telescope has confirmed controversial Hubble Telescope measurements that seemingly contradict the standard model of cosmology, giving rise to what is known as the ‘Hubble Tension,’ according to new findings involving the most extensive study of the universe’s expansion ever conducted. Confirmation of the decades-long Hubble Tension, which reveals that the universe is expanding faster than cosmological models predict, has sent astrophysicists back to the drawing board in search of previously unknown physics that could account for the measurements, potentially rewriting the standard model. “The discrepancy between the observed expansion...

    Europe’s ultra-powerful new WEAVE telescope, undergoing its inaugural ‘first-light’ instrument activation, recorded a collision between galaxies in a region of deep space called Stephan’s Quintet, where one of the galaxies was traveling at two million miles per hour. Designed to study the composition of stars and galaxies, the William Herschel Telescope is a 20-million Euro collaboration between France, Italy, the UK, the Netherlands, and Spain, with the latter hosting the actual facility in La Palma. The facility’s Enhanced Area Velocity Explorer (WEAVE) wide-field spectrograph’s Large Integral Field Unit (LIFU) is the first of the telescope’s instruments to be activated and...

    Moscovium and nihonium have been identified as more reactive than flerovium, demonstrating the significance of relativistic effects in superheavy elements. Research on moscovium and nihonium shows they are more reactive than flerovium and subject to notable relativistic effects, broadening our understanding of superheavy elements and their potential uses. An international team led by scientists from GSI/FAIR in Darmstadt, Johannes Gutenberg University Mainz, and the Helmholtz Institute Mainz has successfully determined the chemical properties of the artificially produced superheavy elements moscovium and nihonium (elements 115 and 113).
