By solving a decades-long mystery about the sun, researchers have set off a scientific ripple that could alter conceptions of the universe as a whole.
In the first scientific data to emerge from the Sudbury (Ontario) Neutrino Observatory (SNO) in Canada, physicists have found evidence that their most fundamental theory of the universe–the so-called standard model (SN: 7/1/95, p. 10) –contains a major flaw. They've also uncovered a new clue to the composition of the dark matter thought to make up 95 percent of the mass of the cosmos.
The revelations arise from a new study of the neutrino, an elusive form of matter. Neutrinos come in
