Physicist Sean Carroll spends a lot of time researching theoretical aspects of cosmology, field theory, and gravitation. Recently, he’s been speaking out about the Higgs Boson, or "The God Particle" which is a particle of an atom. Without it, the atom could not exist. In his new book The Particle at the End of the Universe he talks about "The God Particle." He joins us to talk about his passion for physics and explains it in a language we can all understand, when Charlotte Talks.
