A study published in Nature Astronomy has found a nearly 3-sigma statistical preference for non-zero interactions between ...

For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark ...

In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery birth like the Big Bang, this idea suggests the cosmos has been growing in ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

Dark energy makes up roughly 70% of the universe, yet we know nothing about it. Around 25% of the universe is the equally mysterious dark matter, leaving just 5% for everything that we can see and ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being ...

Our universe is shrouded in mystery, with about 70 percent of it consisting of dark energy. The exact nature of dark energy remains a puzzle that, once solved, could unlock profound insights into the ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

“Dark energy” is a term scientists use to refer to whatever is causing the universe to expand faster over time. We don’t know exactly what dark energy is—no one has ever directly seen or measured ...
