Spacetime. Tiny elements create bizar universes.

Thimothy Budd, of the Niels Bohr Institute (NBI) of Copenhagen University, does research on models of quantum grafity. He tries to find connections between microscopic models of space-time and Einstein’s classical theory of general relativity. The pictures represent the development of space and time according to special mathematical computations. From one startingpoint tiny elements of spacetime, …
