After five years of staring unblinking at the sky, the Atacama Cosmology Telescope (ACT) has compiled the most detailed map we've ever seen of the cosmic microwave background – the faint light that ...

A new map of cosmic expansion suggests that dark energy evolves over time, hinting that the universe doesn’t work the way we ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy ...

The standard model of how the universe works involves the widely accepted theory that dark energy is a fundamental constant ...

Combining the DESI data with other experiments shows signs that the impact of dark energy may be weakening over time—and the ...

A map of the CMB published by ACT researchers. Research by the Atacama Cosmology Telescope collaboration has led to the clearest and most precise images yet of the universe’s infancy, the cosmic ...

Dark energy, the mysterious phenomenon that powers the expansion of the universe, may undergo periodic 'violent transitions' ...

This is a measure of how clumpy matter is in the universe ... a measurement of a phenomenon called the baryon acoustic oscillation, a pattern in the arrangement of galaxies at very large scales ...

For years, scientists have used a well-established model to explain how the universe evolves. The standard theory, called the ...
