But the really important question is of course whether it is actually true that the neutrinos were travelling faster than light.
Shining an appropriate light on such a wire from the outside would alter its refractive index (a measure of how fast light travelling inside the wire can move).
But travelling asset-light has not always worked in its favour.
That is a hard question to answer, because light travelling along a fibre subtly changes the properties of the fibre itself, in a way that is difficult to model.
ECONOMIST: Optical fibres could carry more information in the future
When light travelling through the core deviates from its course and hits the cladding, the boundary between the two acts as a mirror, and the errant light is reflected back into the core.
Dr Lieu supposed that light, travelling over very long distances, would have to spread out a bit if there was any uncertainty in time.
' and he said 'I imagine myself sitting on a beam of light and travelling through space and I said now what will I see?
BBC: Philip Glass: Have a sleep during Einstein on the Beach
The paper, which you can read here, notes that neutrinos at the recorded energies that were travelling faster than the speed of light should should be radiating particles as the neutrinos were travelling.
If you're caught you will get sent to D-Block solitary, a tiny cube where days are marked by a light shaft travelling across the wall - or you might be interrogated using techniques only alluded to in the otherwise thorough Alcatraz audio tour, with first-hand accounts by prison guards and prisoners of the Rock.
Now he knew he'd be travelling at the speed of light and yet he correctly surmised that he would see everything else rushing past him and he would feel like he was standing still.

In addition, since a single electron travelling through the device emits light not once (as in most other lasers), but many times, quantum cascade lasers are powerful: Dr Capasso's group has recently shown that they beat conventional semiconductor lasers by a factor of 20.
She began to fill her lectures with tales of her out-of-the body experiences, including travelling through space at the speed of light.
Because radiation from the Crab nebula is so energetic, the electrons that created it must have been travelling very close to the speed of light so close that the difference between the two speeds would bump up against Planck-scale graininess, and show up in the spectrum of the radiation.
If it was in a distant galaxy, it would have to be travelling at several thousand times the speed of light to move as much as it has.
Consider: Your first match is set aboard a spacecraft travelling through the cosmos at the speed of light Run past one of the ship's many windows and you'll see stars whizzing by outside.
Two beams of particles will be fired down pipes running through the magnets - travelling in opposite directions at close to the speed of light.
And when such a collision does occur, the pattern of light produced gives away not only the type of neutrino, but the direction it was travelling in.
The anti-stain wipes are good too, especially if you are travelling with only one pair of trousers (I should have mentioned that dark corduroys are better than light ones from this point of view).
In light of Israel's diplomatic assets, Foreign Minister Avigdor Lieberman, who in recent months has been travelling the globe to cultivate bilateral ties with countries in South America, Africa, Central Asia, and Central Europe, should be congratulated for his efforts.
