Could the key to understanding quantum gravity, one of the most sought-after theories in physics, be much more elementary than many physicists believe? Theoretical physicist Renate Loll has developed an elegant theory called Causal Dynamical Triangulations (CDT) that has produced surprising findings while simulating quantum gravity inside a computer. Her research may one day lead to new insights into how the fabric of space-time formed.
