Neil deGrasse Tyson and Sean Carroll dive deep into the nature of reality through the lens of quantum field theory, exploring whether particles like electrons actually “exist” or are just vibrations in invisible fields. They trace the evolution of the idea of fields from Newton and Faraday to modern quantum physics, ultimately questioning what is fundamentally “real” in our universe. The conversation culminates in a philosophical and scientific meditation on the wave function of the universe and whether reality is best described as a vector in Hilbert space.
