A team of astronomers has created the largest 3D map of our universe to date and tracked dark energy's influence on the ...

The 3D cosmic map building DESI has provided more clues that dark energy is weakening over time, suggesting our best model of cosmic evolution could be wrong.

The Dark Energy Spectroscopic Instrument (DESI) is mapping millions of celestial objects to better understand dark energy—the mysterious driver of our universe's accelerating expansion. Today, the ...

The universe’s expansion is accelerating, not decelerating. Our understanding of how the universe works may need an update.

The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) telescope took its ...

Theoretical physicists James Hartle and Stephen Hawking, for example, proposed that rather than having a strict beginning as we would understand it, the universe evolved out of a "no-boundary" state ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as ...

An international team of scientists has released a "3D map of the universe", built ... The current model — known as the Lambda-CDM model — posits the universe has been expanding due to a ...

Fresh DESI data suggests dark energy may evolve over time, contradicting long-standing cosmic expansion theories.

This hints that our best theory of the universe's evolution, the standard model of cosmology ... gravity as the instrument builds the largest 3D map of the universe ever. | Credit: DESI ...
