      Why Neutrinos Might Wimp Out

      Particles that go beyond light speed? Not so fast, many theoretical physicists say

      Faster-Than-Light Neutrinos Aren't

      The same lab that first reported the shocking results last year, which could have upended modern physics, now reports that neutrinos "respect the cosmic speed limit"
      So Much for So Little: Giant Experiments Seek Out Tiny Neutrinos [Slide Show]


      The Super-Kamiokande detector in Japan, an underground tank that holds 50 million liters of water, captures neutrinos that emanate from a particle accelerator nearly 300 kilometers away...

      Brian Greene Talks Faster-Than-Light Neutrinos

      Physicist Brian Greene, host of the NOVA series The Fabric of the Cosmos, addresses the question of faster-than-light neutrinos at a Q&A session after the debut of the PBS series...

      Hidden Neutrino Particles May Be a Link to the Dark Sector

      An experiment aims to find a rumored new type of neutrino that could be a portal to the universe’s dark matter

      2015 Nobel Prize in Physics

      The 2015 Nobel Prize in Physics goes to Takaaki Kajita and Arthur B. McDonald for the discovery that one kind of neutrino can change into another, which shows that neutrinos have mass ...

      Detecting Massive Neutrinos

      A giant detector in the heart of Mount Ikenoyama in Japan has demonstrated that neutrinos metamorphose in flight, strongly suggesting that these ghostly particles have mass

      Exotic Space Particles Slam into Buried South Pole Detector

      The IceCube experiment has taken hits from three neutrinos carrying energies above the outlandishly high peta–electron volt range that suggest they may radiate from titanic explosions in the depths of space

      Not So Fast: Independent Measurement Shows Neutrinos Don t Exceed Speed of Light

      Albert may still be right. An attempt to repeat an experiment that showed a subatomic particle traveling faster than the speed of light suggests that the earlier result may have erred, and that Einstein’s famed special theory of relativity remains intact.A mostly European collaboration of physicists working on an experiment called ICARUS announced today that they had tracked neutrinos traveling from CERN, the particle physics lab outside Geneva, to the Gran Sasso National Laboratory, in an Italian mountainside...

      Faster-than-light neutrinos show science in action

      Unless you've been hiding under a rock for the past 24 hours, you've probably heard about the neutrinos that turned up at the Gran Sasso Laboratory in Italy a few nanoseconds earlier than they were supposed to, in a feat that would have required them to travel faster than the speed of light.The story has been covered by many news outlets already, and, while some headlines may have raised a few eyebrows, most of the coverage has been suitably cautious...

      What next for neutrinos?

      To catch a neutrino (MINOS) For a ghostly type of particle, oblivious to even the massive bulk of a star or planet, neutrinos sure can generate a fuss.

      Superluminal Neutrinos Would Wimp Out En Route

      [Note: October 5 update and clarification added at the bottom] Neutrinos that go beyond light speed? Not so fast, say two theoretical physicists.In a terse, peremptory-sounding paper posted online on September 29, Andrew Cohen and Sheldon Glashow of Boston University calculate that any neutrinos traveling faster than light would radiate energy away, leaving a wake of slower particles analogous to the sonic boom of a supersonic fighter jet...

      Extragalactic Neutrinos in South Pole Experiment Reveal Distant Universe

      Dozens of particles from halfway across the universe have landed in the IceCube experiment at the South Pole. These messengers could help answer some long-standing cosmic conundrums
