Abstract
The gravitational form factors encode fundamental particle properties including mass, spin, and $D$-term. Their physical interpretation promises, for composed particles, insights on spatial distributions of energy, angular momentum, and internal forces. This Colloquium reviews the theoretical and recent experimental advances in this field with focus on the quark-gluon structure of the proton in QCD.
