protons and
neutrons (which are made of
"up" quarks and "down"
quarks), strange nuclei also
have so-called Lambda
particles that contain another
flavor of quark called
"strange" as well. These
Lambda particles orbit
around the protons and
neutrons.
If all that is a little much to
straighten out, just think of
anti-hypertritons as several
kinds of weird.
Though they normally don't
exist on Earth, these
particles may be hiding in the
universe in very hot, dense
places like the centers of
some stars, and most likely
were around when the
universe was extremely
young and energetic, and all
the matter was packed into a
very small, sweltering space.
"This is the first time they've
ever been created in a
laboratory or a situation
where they can be studied,"
said researcher Carl
Gagliardi of Texas A&M
University. "We don't have
anti-nuclei sitting around on
a shelf that we can use to
