new test results...
An experiment to repeat a test of the speed of subatomic particles known as neutrinos has found that they do not travel faster than light.
Results announced in September suggested that neutrinos can exceed light speed, but were met with scepticism as that would upend Einstein's theory of relativity.
A test run by a different group at the same laboratory has now clocked them travelling at precisely light speed.
The results have been posted online.

neutrinos at the opera...
...
What was missing was information from Cern about the departure time of the neutrinos, which the team recently received to complete their analysis.
The result: they find that the neutrinos do travel at the same speed as light, within a small error range.
"We are completely compatible with the speed of light that we learn at school," said Sandro Centro, co-spokesman for the Icarus collaboration.
Dr Centro said that he was not surprised by the result.
"In fact I was a little sceptical since the beginning," he told BBC News. "Now we are 100% sure that the speed of light is the speed of neutrinos."
Most recently, the Opera team conceded that their initial result may have been compromised by problems with their equipment.
