Explanation:
Two thousand meters below the ground, a giant sphere
has begun to detect nearly invisible particles. These particles,
neutrinos, are
extremely abundant in the universe but usually
go right through just about everything.
By stocking
this 12-meter sphere with an unusual type of
heavy water and surrounding it with light detectors,
astrophysicists hope to catch the occasional collision.
Since the Sudbury Neutrino Observatory (SNO) is
sensitive to all types of
neutrinos, future results
might hold clues to how much
neutrinos change types on the fly,
how our own
Sun emits neutrinos, and even how
important neutrinos are to the composition of the
entire universe.
