Physicists
have repeatedly challenged the theory with experiment, but the behaviors
the theory described always materialized. Measurements matched theory
decimal for decimal.
The
Standard Model even described particles and forces that no one had ever
seen before, but later found — a stunning confirmation of the theory's
enormous predictive power.
Like
Mendeleev's periodic table of the chemical elements, the Standard Model
has simplified the physical world. But now physicists are looking for
the equivalent of an atomic theory to explain its whys and hows.
Intent
on answers, physicists have pressed ahead with mathematical theories to
extend the Standard Model.
Hiding
behind the quarks and gluons, the equations say, lie new particles and
new forces — indeed, a whole new
physics.
With
powerful tools coming on line to pry deep into both inner space and outer
space, physicists will soon begin to tell us why matter is the way it
is.
