Since the other thread is over-crowded I thought I would speculate on this one here.
I have two hypotheses-
1. Neutrinos are able to modulate the speed of time when they travel in these clumps. This would support the fluctuation in decay rates as a measure of neutron density (but not really, because any time piece would also experience this fluctuation in time and so no net difference). This could probably be measured with the right equipment - a neutrino source and some method of measuring the speed of light passing through it.
2. I am almost willing to bet that the speed of neutrinos is smaller than c through vacuum. Scharnhorst effect and other related principles would be the source of this difference. Its not that neutrinos are travelling faster than light, its that time is moving more quickly for the neutrinos. If light were to pass through several hundred kilometers of rock it would also appear to be moving faster than c in my opinion.
