Are Virtual Particles A New Layer of Reality?

The video explores the concept of virtual particles in quantum physics, explaining their role as mathematical tools in quantum field theory. It discusses how virtual particles are used in perturbation theory to approximate complex interactions and highlights their properties and misconceptions. The video also examines the role of virtual particles in a vacuum and concludes that they are likely mathematical artifacts rather than physical entities.
