A Nobel for the Study of Nature’s Poltergeists
My updates to this blog have been quite sporadic of late, as life has been having a tendency of getting in the way. However, I could not let this week go by without noting this year’s Nobel Prize for Physics, … Continue reading
Last Nail in the Coffin for Superluminal Neutrinos
The ICARUS Experiment, operating at the same Gran Sasso location as the OPERA Experiment, has conducted its own measurement of the speed of neutrinos from CERN, and the results are consistent with the neutrino velocity between constrained by the speed … Continue reading
Putting the OPERA Affair in Perspective
Jon Butterworth has an excellent editorial in The Guardian that puts the whole FTL fiasco in its proper light…..
How a Supernova Gave Birth to Neutrino Astronomy 25 Years Ago Today
On February 23, 1987, the astronomy world was abuzz. Astronomers Ian Shelton and Oscar Duhalde at the Las Campanas Observatory in Chile noticed that a bright new point of light had appeared in the Large Megellanic Cloud. It did not … Continue reading
Not a Big Shocker
Regarding those supposed FTL neutrinos detected by the OPERA Collaboration: BREAKING NEWS: Error Undoes Faster-Than-Light Neutrino Results – ScienceInsider UPDATE: More authoritative sources are reporting the possibility of TWO distinct sources of experimental error having been identified: Flaws found in … Continue reading
OPERA Redux
The members of the OPERA collaboration have taken to heart one of the primary criticisms leveled at their experimental method: the possibility that the particle bunches used might be so long as to introduce sampling errors in their timing measurements. … Continue reading
ICARUS Nixes OPERA’s Superluminal Neutrino Result
As described here, the OPERA project at Gran Sasso Laboratories recently published an article describing what appears to have been the detection of superluminal neutrinos coming from CERN. As Tommaso Dorigo explains in this blog post, new results from the … Continue reading
FTL Neutrinos? Not so fast….
Rumors have been circulating for a few days that the OPERA Collaboration would today announce the detection of what appear to have been neutrinos from CERN arriving at the Gran Sasso detector in Italy (a distance of 730 kilometers) a … Continue reading
