Bloomberg (April 2) -- The Standard Model of physics is what scientists consider their working picture of how fundamental particles behave and interact. But it “has some holes in it,” says Verena Martinez Outschoorn, an assistant professor of physics at Illinois. “We know that our worldview, our model, our understanding of particles and their interactions is kind of a subset of a bigger picture,” she says. “We have reason to believe there are other particles out there.”
