Atacama Telescope Reveals Detailed Images of the Early Universe

New findings confirm the universe's age and standard model but leave key questions about its expansion unresolved.

The Atacama Cosmology Telescope captured images of the universe as it appeared 388,000 years after the Big Bang.
These images confirm the universe's age as 13.8 billion years with less than one percent uncertainty.
The findings support the Lambda Cold Dark Matter model, the prevailing framework for understanding the universe's composition and evolution.
Researchers highlighted the unresolved tension between different measurements of the Hubble constant, a key parameter in understanding cosmic expansion.
The results, not yet peer-reviewed, will be presented at the American Physical Society conference on March 19, with future advancements expected from the Simons Observatory.
