Problem
Quantum gravity is difficult to communicate because many approaches are mathematically dense and hard to experiment with. I wanted a simulation path that is scientifically rigorous but still approachable to readers who are new to the topic.
Approach
- Model spacetime with Causal Dynamical Triangulations (CDT), enforcing causality at small scales.
- Reformulate the physical model as a discrete statistical mechanics problem.
- Use Hastings-Metropolis Monte Carlo sampling to evaluate geometric fluctuations efficiently.
- Keep the implementation lightweight enough to run from laptops up to larger compute systems.
Key finding
The simulations recover large-scale behavior consistent with classical spacetime while still exposing nontrivial small-scale fluctuations. This makes CDT a practical computational bridge between abstract theory and measurable model behavior.
Why it matters
This project demonstrates that frontier physics can be made experimentally accessible through simulation. That accessibility helps with both teaching and early-stage method validation.
Outputs
