scibyte50 Neutrinos

  • Five different teams of physicists have now independently verified that elusive subatomic particles called neutrinos do not travel faster than light
  • instead of the nail in the coffin of faster-than-light neutrinos, the new suite of results is more like the sod planted atop their grave
  • OPERA team also discovered that a loose fiber optic cable had introduced a delay in their timing system that explained the effect
  • ...5 more annotations...
  • A month later
  • measured the speed of neutrinos fired from CERN and found that they travel at light speed, as predicted
  • Some OPERA team members thought the whole episode had besmirched the collaboration's reputation, and in March, two of the team's elected leaders lost a vote of no confidence and tendered their resignations.
  • Gran Sasso houses four particle detectors
  • All four have now found that the neutrino's speed is consistent with the speed of light

  • This technique can also allow you to calculate the numbers you need for more sophisticated locomotor reconstructions, such as the running simulations we have produced in the past
  • estimated weight for this dino, along with other species, has been dropping since about the early 1960’s.
  • primary limitation, for now, is that the specimen should consist of a complete skeleton that has been mounted
