See a Black Hole

Authors: George Rajna

In the shadowy regions of black holes two fundamental theories describing our world collide. Can these problems be resolved and do black holes really exist? First, we may have to see one and scientists are trying to do just this. [25] The authors suggest that this virtual reality simulation could be useful for studying black holes. [24] Every galaxy is thought to harbor a supermassive black hole in the center, or nucleus, of the galaxy, and in active galaxies this black hole is fed by infalling matter. [23] A new study by researchers at the University of Colorado Boulder finds that violent crashes may be more effective at activating black holes than more peaceful mergers. [22] For the first time, a team of astronomers has observed several pairs of galaxies in the final stages of merging together into single, larger galaxies. [21] In a cluster of some of the most massive and luminous HYPERLINK "https://phys.org/tags/stars/" stars in our galaxy, about 5,000 light years from Earth, astronomers detected particles being accelerated by a rapidly rotating neutron star as it passed by the massive star it orbits only once every 50 years. [20] For the first time astronomers have detected gravitational waves from a merged, hyper-massive neutron star. [19] A group of scientists from the Niels Bohr Institute (NBI) at the University of Copenhagen will soon start developing a new line of technical equipment in order to dramatically improve gravitational wave detectors. [18] A global team of scientists, including two University of Mississippi physicists, has found that the same instruments used in the historic discovery of gravitational waves caused by colliding black holes could help unlock the secrets of dark matter, a mysterious and as-yet-unobserved component of the universe. [17] The lack of so-called “dark photons” in electron-positron collision data rules out scenarios in which these hypothetical particles explain the muon’s magnetic moment. [16]
