  • Unprecedented look at electron: Size limit for undiscovered subatomic particles determined
    on October 17, 2018 at 6:09 pm

    A new study suggests that many theorized heavy particles, if they exist at all, do not have the properties needed to explain the predominance of matter over antimatter in the universe. If confirmed, the findings would force significant revisions to several prominent theories posed as alternatives to the Standard Model of particle physics, which was developed in the early 1970s.

[…]

  • The state of the early universe: The beginning was fluid
    on October 15, 2018 at 3:35 pm

    Scientists recently collided Xenon nuclei, in order to gain new insights into the properties of the Quark-Gluon Plasma (the QGP). The QGP is a special state consisting of the fundamental particles, the quarks, and the particles that bind the quarks together, the gluons. The result was obtained using the ALICE experiment at the superconducting Large Hadron Collider. […]

  • New telescope almost doubles known number of mysterious 'fast radio bursts'
    on October 10, 2018 at 5:23 pm

    Astronomers have nearly doubled the known number of 'fast radio bursts'-- powerful flashes of radio waves from deep space. The team's discoveries include the closest and brightest fast radio bursts ever detected and they have proved that fast radio bursts are coming from the other side of the Universe rather than from our own galactic neighborhood. […]

  • The cosmological lithium problem
    on October 9, 2018 at 2:25 pm

    An international research group has tried to find a solution to one of the unknowns in the current description of the Big Bang. Different nuclear reactions responsible for the creation and destruction of atomic nuclei in nucleosynthesis during the Big Bang are crucial in determining the primordial abundance of lithium, the third (and last) chemical element formed during the very early phase of the creation of the universe. […]

  • String theory: Is dark energy even allowed?
    on October 9, 2018 at 2:24 pm

    In string theory, a paradigm shift could be imminent. In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible with our current understanding of 'dark energy'. A new study has now found out that this conjecture seems to be incompatible with the existence of the Higgs particle. […]

  • Observations challenge cosmological theories
    on October 4, 2018 at 5:18 pm

    Since the big bang, fewer galaxy clusters have formed over time than was actually expected. Physicists from the have now confirmed this phenomenon. For the next years the researchers will analyze their data in even greater detail. This will put them in a position to confirm whether the theories considered valid today need to be reworked. […]

  • Black holes ruled out as universe's missing dark matter
    on October 2, 2018 at 2:27 pm

    If dark matter consists of a plethora of primordial black holes, then their gravitational lensing -- magnifying and brightening distant objects -- should be detectable. Physicists analyzed 740 known supernovas to find the handful that should have been magnified and brightened by black holes, and found none. This puts a strong upper limit, 40, on the percent of dark matter that can consist of black holes, and suggests that none of it is. […]

  • Laser breakthrough has physicists close to cooling down antimatter
    on August 22, 2018 at 5:10 pm

    For the first time, physicists at CERN have observed a benchmark atomic energy transition in anithydrogen, a major step toward cooling and manipulating the basic form of antimatter. Antimatter, annihilated on impact with matter, is notoriously tricky to capture and work with. But its study is key to solving one of the great mysteries of the universe: why anti-matter, which should have existed in equal amounts to matter at the time of the Big Bang, has all but disappeared. […]
