Halo of Neutrinos Alters Physics of Supernovae

  Sparse halos of neutrinos within the hearts of exploding stars exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent events. The titanic supernova, called SN 1987A, blazed with the power of 100 million suns for several months following its discovery on [continue reading]

Are Neutrons Escaping to a Parallel World?

  An anomaly in the behaviour of ordinary particles may point to the existence of mirror particles that could be candidates for dark matter responsible for the missing mass of the universe. Berezhiani Parallel World Graphic: Anomalous loss of neutrons observed experimentally. The positive result (anomaly) corresponds to the gray-shaded areas.   In a paper recently [continue reading]
