Corrected gravity

Comparison between a simulation of the universe in the ΛCDM model and a simulation including massive neutrinos and corrected gravity.

Artificial intelligence learned the laws of the universe – then struggled to identify new physics

Researchers trained a neural network first on the standard cosmological model and then on models that included massive neutrinos, corrected gravity, and primitive non-Gaussianity. The method saved expensive simulations, but in some cases caused “transfer”
