Editor's note: Sean Carroll is a theoretical physicist at Caltech, and author
of the upcoming "The Particle at the End of the Universe: How the Hunt for the
Higgs Boson Leads Us to the Edge of a New World."
(CNN) -- The incredible discovery of the Higgs boson will open up new ways of
probing the part of the universe that is invisible to our everyday senses:
beyond ordinary matter, into the extraordinary world of dark matter.
It isn't often that you get to be physically present at an historic occasion,
but I was at CERN on July 4 when scientists at the Large Hadron Collider
announced the discovery of the Higgs boson particle.
Hundreds of young physicists had camped out from the previous night just to get
good seats at the technical seminars proclaiming the discovery. What we
witnessed was the first solid evidence for the particle that explains how other
particles like electrons and quarks get to be massive.
Part of the excitement stems from the fact that the Higgs boson is the final
piece in an extremely elaborate puzzle: the Standard Model of particle physics.
This boringly named theory has loomed triumphantly over physics for the past 40
years, withstanding all experimental challenges. With this final piece in
place, we can justifiably say that we understand the behavior of ordinary
matter -- the atoms and molecules that make up ourselves and our everyday world.
Why is the 'God particle' a big deal?

Much more of the excitement, however, had a deeper basis: if the Higgs is the
final chapter in one story, it's also the prologue to our next adventure. This
is true literally as well as figuratively.

As successful as the Standard Model has been, we know it's not the final answer
to how the universe works. Strong evidence comes from the existence of dark
matter: mysterious, invisible stuff that adds up to five times as much mass as
the ordinary atoms and particles in the universe.
We know enough about dark matter to be sure that it's not just some kind of
ordinary matter that is hiding in the shadows. It is something truly new,
something we haven't yet directly seen here on Earth.
But we're trying. Multiple experiments are underway to look for the dark matter
particles we think are all around us. Not only are they "dark," these particles
hardly interact with ordinary matter at all.
It's possible, even likely, that millions of them pass through your body every
second. It's like a city with two populations, each speaking a different
language, and no translators or bilingual interpreters. The two groups of
people go about their separate lives, never directly speaking with each other.
Likewise, in our galaxy, dark matter and ordinary matter pass right through
each other all the time.
The Higgs boson could be the bilingual particle we've been looking for. We
don't know exactly what the dark matter is, but we certainly have our favorite
theories. In many of those models, the Higgs is the one particle that readily
interacts both with ordinary protons and neutrons and also with dark matter.

There are several experiments currently running with the goal of detecting dark
matter. Typically they are deep underground, shielded from cosmic rays and
other sources of noise, kept in environments that are as quiet as possible.
Dark matter particles are able to penetrate through the Earth and pass right
through the detector. Most do so unmolested, but occasionally we'll get lucky
and one will interact with the nucleus of an atom, leaving a bit of energy
behind. Our best theoretical guess is that the way that interaction will happen
is through the exchange of Higgs bosons.
Knowing something about the Higgs will be enormously helpful in figuring out
the implications if one of these experiments finds a strong dark-matter signal
-- something we're hopeful could happen in the near future.
We're not just waiting around for dark matter to be detected, either. Now that
we've found the Higgs, we can start studying its properties in detail. How is
it made? How does it decay? Are its properties those predicted by the Standard
Model, or are there hints of something new going on?
If everything breaks just right, we may be able to produce dark matter directly
at the Large Hadron Collider. It won't be easy, precisely because dark matter
interacts so weakly. Even if you make it, it's hard to be sure, because the
antisocial dark matter particles tend to zip out of your experiment without
leaving any trace behind.
But once we better understand the Higgs and the particles it decays into, we
might be able to infer the presence of dark matter just by process of
elimination, by pinpointing events in which more energy went into the collision
than we detected coming out.
Even though it wasn't discovered until 2012, the Higgs boson was proposed back
in 1964. It is very much a child of the 20th century. In particle physics and
cosmology, the 21st century promises discoveries that will help illuminate the
dark universe around us.
That's the great thing about history being made: you know things are different
now, but you can't be sure where you're going to go next.
