The world’s first neutrino observation in a hydrogen bubble chamber. It was found November 13, 1970, on this photograph from the Zero Gradient Synchrotron’s 12-foot bubble chamber. The invisible neutrino strikes a proton where three particle tracks originate (lower right). The neutrino turns into a mu-meson, the long center track (extending up and left). The short track is the proton. The third track (extending down and left) is a pi-meson created by the collision. Image credit: Argonne National Laboratory.

NOvA and T2K Experiments Zero In on Unusual Properties of Neutrinos

In both NOvA (NuMI Off-axis νe Appearance experiment) and T2K experiments, neutrinos are fired from particle accelerators and detected after traveling...

The model proposed by Eto et al. suggests a brief knot-dominated era, when these tangled energy fields outweighed everything else, a scenario that could be probed through gravitational-wave signals. Image credit: Muneto Nitta / Hiroshima University.
