Today on the show, we are joined in the home studio with Dr. Matthew McCullough. Matthew got his Masters of Physics and his doctorate in Theoretical Particle Physics from the University of Oxford in the UK. He is currently working as a theoretical physicist at the CERN laboratory coming up with cool new theories about Dark Matter and our universe.  As a theorists, not to be confused with previous pod guests that were experimental physicists, his job is to think deeply about the rules that govern the universe and to come up with brand new theories about how it all works. We talked about growing up in Belfast, Ireland; getting kicked out of his band; how we know Dark Matter exists; and ultimately, how math underpins the nature of our universe.
