In the real universe—especially at high energies—particles are constantly being annihilated and created. When a cosmic ray hits the atmosphere, or when protons collide inside the Large Hadron Collider (LHC), kinetic energy is transformed directly into new matter. Readers are introduced to the interaction picture, Wick's
