Our interactive simulators let you compare RFT predictions with current models like ΛCDM and MOND across multiple cosmic scales.

Choose a simulator below to explore how RFT resolves cosmological anomalies.

⚠️ Development Notice

Some simulators are currently under active development and testing. Features may be incomplete or change as we refine the implementations.
