The First AI Simulation of the Universe Is Fast and Accurate — and Even Its Creators Don’t Know How It Works By Thomas Sumner

A comparison of the accuracy of two models of the universe. The new model (left), dubbed D3M, is both faster and more accurate than an existing method (right) called second-order perturbation theory, or 2LPT. The colors represent the average displacement error in millions of light-years for each point in the grid relative to a high-accuracy (though much slower) model

Gravitational Waves Will Settle Cosmic Conundrum

When neutron stars collide, they emit light and gravitational waves, as seen in this artist’s illustration. By comparing the timing of the two emissions from many different neutron star mergers, researchers can measure how fast the universe is expanding.
