    Dark Energy Survey reveals most accurate Measurement of Universe’s Dark Matter

    August 7, 2017, Categories  Astronomy/Space, Health/Medical, Physics

    Map of dark matter made from gravitational lensing measurements of 26 million galaxies in the Dark Energy Survey. The map covers about 1/30th of the entire sky and spans several billion light-years in extent. Red regions have more dark matter than average, blue regions less dark matter.

    Imagine planting a single seed and, with great precision, being able to predict the exact height of the tree that grows from it. Now imagine traveling to the future and snapping photographic proof that you were right...

    Designing the microstructure of printed objects. Today’s 3D printers have a resolution of 600 dots per inch, ie they could pack a billion tiny cubes of different materials into a volume that measures just 1.67 cubic inches. Such precise control of printed objects’ microstructure gives designers commensurate control of the objects’ physical properties – eg. density or strength, or the way they deform when subjected to stresses...

    Swansea University scientists at CERN have again made a landmark finding, taking them one step closer to answering the question of why matter exists and illuminating the mysteries of the Big Bang and the birth of the Universe. The physicists from the University’s College of Science, working with an international collaborative team at CERN, describe the first observation of spectral line shapes in antihydrogen, the antimatter equivalent of hydrogen.
     
    Professor Mike Charlton said: “The existence of antimatter is well established in physics, and it is buried deep in the heart of some of the most successful theories ever developed...

    Physicists play leading role in confirming theory predicted 4 decades ago. In 1974, a Fermilab physicist predicted a new way for ghostly particles called neutrinos to interact with matter. More than four decades later, a UChicago-led team of physicists built the world’s smallest neutrino detector to observe the elusive interaction for the first time. Neutrinos are a challenge to study because their interactions with matter are so rare...
