Nature Communications, Published online: 30 April 2026; doi:10.1038/s41467-026-72774-1 The authors propose and experimentally demonstrate a scheme for weaving optical topological knots and links that are fully localized in space–time, thereby breaking the conventional constraint of longitudinal space-filling via Milnor polynomials.
