Birth of Space-Time (IMAGE) University of Warsaw, Faculty of Physics Caption In the mathematical model constructed by theorists at the Department of Physics, University of Warsaw, classical space-time is created by the interaction of matter with quantum gravity. The process resembles how an ice crystal lattice (symbolizing classical space-time) is formed by freezing liquid water (quantum gravity). Recent studies on the model suggest that different elementary particles generate different classical space-times.
