The Universe is woven into a vast cosmic web of galaxies, clusters, and filaments, but modeling such complexity has always demanded supercomputers and immense time.

Now, scientists have introduced Effort.jl, an innovative emulator that mimics the behavior of advanced cosmological models with striking accuracy, sometimes even improving on them, while running in minutes on a laptop.

The Vast Skeleton of the Universe

A single galaxy may seem enormous, but compared with the entire Universe it is no more than a pinpoint. Countless galaxies gather into clusters, which themselves combine into vast superclusters. These assemble into immense filaments interlaced with empty regions, forming a colossal three-dimensional framework known as the cosmic web.

Trying to grasp such an immense structure is far from simple. To make sense of it, researchers bring together physical theories of the Universe with observations from telescopes and other instruments. They then construct theoretical models, one of the most important being EFTofLSS (Effective Field Theory of Large-Scale Structure). With data as input, these models provide a statistical description of the cosmic web and make it possible to calculate its fundamental properties.
