Hmmm well, my cable idea wouldn't account for 60ns unless it was 20 meters of cable. Oh well.

Another fun thing to look at is the neutrino emissions from a supernova. SN1987A is a distance of 168,000 LY away. If you take the difference in speed the article from cern suggests and multiply, you get that you should receive a burst 4 years before the light arrives. BUT! The neutrinos ended up arriving the same day.

(The neutrinos did beat the light by 3 hours, but that's another story....)
