Explanation:
Why do objects have mass?
To help find out,
Europe's
CERN has built the
Large Hadron Collider
(LHC), the most powerful
particle accelerator
yet created by
humans.
Since 2008, the
LHC smashed protons into each other with
unprecedented impact speeds.
The LHC
is exploring the leading explanation that mass arises from
ordinary particles slogging through an otherwise invisible but pervasive
field of
virtual Higgs particles.
Were high energy colliding particles to create real
Higgs bosons, the
Higgs mechanism
for mass creation will be bolstered.
Last week, two LHC
groups reported on preliminary indications that the Higgs boson might exist
around 120 GeV in mass.
Data from the LHC collisions is also being scanned for
micro black holes,
magnetic monopoles,
and explore the possibility that every type of
fundamental particle
we know about has a nearly invisible
supersymmetric counterpart.
You can help -- the LHC@Home
project will allow anyone with a home computer to help
LHC scientists
search archived LHC data for these strange beasts.

LHC.
