AI uncovers the universe’s ‘settings’ with unprecedented precision, and it could help to resolve the Hubble tension
By Ben Turner
Astrophysicists have leveraged AI to fine-tune estimates of the universe’s cosmological parameters with unmatched precision. These parameters, which describe the makeup of the universe, from dark matter to its expansion, are key to understanding how the universe began and where it’s headed. By using AI, researchers could analyze smaller-scale data that traditional methods missed, halving the uncertainty of earlier estimates. This breakthrough might even help resolve the Hubble tension, a long-standing mystery about the universe’s expansion rates. Future cosmic surveys could push our understanding further, possibly leading to new physics.
