What are virtual particles?

Virtual particles are one of those topics of modern physics that just don’t sound real. How can particles just appear and disappear without anyone seeing them. In this video, Fermilab’s Dr. Don dives into the topic, giving us an understanding of how virtual particles arise from quantum field theory.
