Invisibility Cloaks for Stress Waves

Authors: George Rajna

Despite casting deep doubt on dozens of theoretical papers on "elastodynamic" cloaking, the new study's authors from the Georgia Institute of Technology don't think civil engineers should completely give up on it, just on the idea of an ideal cloak. [19] University of Southern Denmark researchers have conducted simulations of dark matter particles hitting the Earth. [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]
