Neutrino Oscillations Confirmed

mfg writes "The Sudbury Neutrino Observatory has found evidence that neutrinos can change type between the Sun and Earth. See the BBC news story for more details."

I think we should drag the neutrino to courts. After all they changed type without telling us. This caused so much difficulty to scientists. These guys are hiding their source code!! So they should'nt be treated different from Bill, cya in court guys

Boredom?

Well, it's a bloody long way, do you really think they'd sit still? More likely they'd jump around on the back seat, play I-spy and shout "Are we there yet?" every million miles or so...

I've been confused about neutrinos ever since I found out they had mass. Who'd have imagined that they were Catholic?

Wasn't it done by Super Kamiokande experiment back in 1998?

This was the anouncement of the atmospheric neutrino results which pinned down neutrino mixing between muon and tau nus better than ever before.

SK also sees solar nus but only the electron neutrinos. In addition to the electron neutrino, SNO can also see the sum of all solar neutrino types (ie, the electron type as well as other types that the e-type may have oscillated to). Their first result relied on SK's measurement of the electron type nus because SNO has a smaller mass, thus lower count. The latest announcement appears to be stating that they have collected enough events that they can have a similar result as before but with out relying on some of SK's data.

That can't be true, I saw Wesley use a tunneling neutrino beam to rid the Enterpise of bacteria. Star Trek wouldn't lie to me, would it?

All the neutrinos are born Catholic, but only a third of them are Catholic by the time we detect them. The rest oscillate to other faiths, which are also known to have mass, just in different amounts.
