[ad_1] In 1930, theoretical physicist Paul Dirac was trying to reconcile quantum mechanics with Einstein’s theory of relativity when his equations hinted at something strange: the existence of a “mirror” particle identical to the electron, but with opposite charge. Its implications made him uneasy  — that every particle has an antiparticle, and that perhaps the […]

[ad_1] Thanks to a study that used 12 years of data from NASA’s Fermi Gamma-ray Space Telescope, scientists are finally getting close to accurately identifying PeVatrons, the source of some of the highest energy particles that whip across our galaxy. The study has been documented in a research article published in Physical Review Letters. Streams […]
