Phil et al:
Within the last decade or so, physicists concluded that neutrinos have mass, because they oscillate.
If neutrinos have mass, does this mean they are Catholic?
The CERN test involved firing neutrinos over a 454 mile course from transmitter to receiver. The neutrinos arrived 60 nanoseconds sooner than expected. At 454 miles, the 60 nanoseconds translates into about 60 feet, which is 0.0025 percent. Perhaps neutrinos are less affected by matter of all kinds, than photons are in the not quite perfect vacuums where previous tests have been carried out.
Presumably, the distance between transmitter/receiver is calculated using GPS technology. One assumes that the relativistic effect of the orbiting GPS clocks has been taken into account.
Which raises another question: How do they synchronize the transmitting and receiving clocks, if they are synchronized at all?
I'm not aware of any studies exploring the interaction between neutrinos and dark matter and dark energy.
Remember, the second test was also conducted at CERN. The theory will gain considerable support when multiple confirming tests are conducted by other, independent laboratories.
While on this esoteric topic, I have an answer to the question about the accelerating rate of expansion of the universe. Mother Nature, in perhaps her finest irony, made the yet-to-be-discovered graviton and its anti-particle mutually repellent, instead of mutually attractive like all particle/anti-particle pairs known to date.
