Quarks and the Strong Force
From the stars overhead to the atoms in our own human DNA, all matter
is composed of fundamental particles — particles that cannot be
divided into smaller parts.
Quarks, we believe, are among the few fundamental particles in the
universe. There are six types of quarks (up, down, charm, strange, top,
and bottom). The lightest quarks — called up and down — are the
Quarks are bound to each other by the strongest force in the universe.
Called simply the strong force, this enormous force binds them so tightly
that one quark cannot exist by itself.
Glued by the strong force, quarks are the building blocks of matter as
we know it. Understanding quarks and the strong force is fundamental to
the universe, our world, and ourselves.
Did you know one quark can never be alone?
