10/14/11 – Ephemeris – The Neutrino problem
Friday, October 14th. The sun will rise at 7:56. It’ll be up for 11 hours and 4 minutes, setting at 7:00. The moon, 3 days past full, will rise at 8:04 this evening.
The news came out a couple of weeks ago that some nuclear physicists apparently measured that neutrinos traveled faster than the speed of light. This needs to be corroborated before it is accepted by the physics world. We do have one good example of neutrinos traveling close to but not faster than the speed of light. That is a supernova in 1987 which was about 168 thousand light years away. The neutrinos arrived 3 hours before the light of the supernova arrived. The reason for the slightly earlier arrival time is that the neutrinos sailed from the core of the star like it wasn’t there. The light, however couldn’t escape until the explosion could push its way to the surface of the star. Neutrinos are wonderful and strange sub atomic particles. Check them out in Wikipedia.
