The path is through 730 kilometers of solid rock, so only neutrinos 
will do.  And neutrinos are the least understood of particles.

If I read the article correctly, the neutrinos appear to travel 25 
parts per million faster than C, which if true is still 
revolutionary.  But while the result is quite significant in 
statistical terms (6 sigma), 25 ppm is pretty small, and could easily 
be caused by some subtle systemic error.

One assumes *very* subtle, given that none of the ~100 coauthors 
could find it, and it won't have been for lack of trying.  Now the 
world physics community is on the case, so it may not take all that 
long.
