A popular-science introduction to the U-Cell Model (UCM), a theoretical physics framework deriving quantum mechanics, gravity, and cosmology from a single Planck-scale elastic lattice substrate. The book covers the structure of space and time, the nature of matter, dark energy and dark matter, and the possibility of interstellar travel — from the smallest scales to the largest structures of the universe. English translation of the German original "Das Universum in einem Punkt" (v1.93).
