Researchers from the Flatiron Institute and collaborators have developed an innovative method that uses artificial intelligence (AI) to estimate the universe's cosmological parameters with unprecedented precision. This breakthrough could reshape how scientists study the cosmos.
The method, called Simulation-Based Inference of Galaxies (SimBIG), extracts hidden insights from galaxy distributions, offering a significant improvement over traditional techniques.
By leveraging AI, the team reduced uncertainty in key parameters, such as the universe’s matter clumpiness, to less than half that of conventional methods. This enhanced accuracy aligns closely with other observations, including measurements of the universe’s oldest light, further validating the approach.
Published in Nature Astronomy, the findings promise to advance our understanding of the universe's fundamental properties. READ MORE...
