Supersymmetry predicts that two basic classes of fundamental particles, fermions and bosons, accompany each other in the same representation. [29] A fraction of a second after the Big Bang, a single unified force may have shattered. Scientists from the CDF and DZero Collaborations used data from the Fermilab Tevatron Collider to recreate the early universe conditions. [28] Now researchers at the Paul Scherrer Institute PSI have helped to better understand the first minutes of the universe: They collected artificially produced beryllium-7 and made it into a sample that could be investigated. [27] Researchers have developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave background radiation. [26] The group's results reinforce a disagreement over the value of the Hubble constant as measured directly and as calculated via observations of primordial radiation – a disparity, say the researchers, which likely points to new physics. [25] Neutron stars consist of the densest form of matter known: a neutron star the size of Los Angeles can weigh twice as much as our sun. [24] Supermassive black holes, which lurk at the heart of most galaxies, are often described as "beasts" or "monsters". [23] The nuclei of most galaxies host supermassive black holes containing millions to billions of solar-masses of material. [22] New research shows the first evidence of strong winds around black holes throughout bright outburst events when a black hole rapidly consumes mass. [21] Chris Packham, associate professor of physics and astronomy at The University of Texas at San Antonio (UTSA), has collaborated on a new study that expands the scientific community's understanding of black holes in our galaxy and the magnetic fields that surround them. [20] In a paper published today in the journal Science, University of Florida scientists have discovered these tears in the fabric of the universe have significantly weaker magnetic fields than previously thought.
