This image, from a sensor at the particle accelerator at CERN, is an example of the data signature a Higgs particle might generate. Researchers will spend into 2012 sifting through data in an attempt to find the Higgs.
Physicists have a grand theory that describes how tiny particles interact to form all the stuff we see in the universe — everything from planets to toasters to human beings.
