Dark energy is one of the greatest mysteries of the universe. This mysterious force is thought to be accelerating the expansion of the cosmos. But a new study challenges this long-held belief. A team ...

Although some compelling evidence exists to support the idea that a repulsive force similar to dark energy exists, it has yet to be directly observed or measured. To circumvent this uncomfortable ...

Studies suggest that the universe's expansion is decelerating — but what could that mean for the future of the cosmos?

Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the accelerating expansion of the universe. However, one competing theory known ...

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 ...

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 ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the ...

“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 ...

In this week’s edition of The Prototype, we look at new findings about dark energy, the state of the quantum technology industry, using magnetic nanoparticles to fight cancer and more. You can sign up ...

Last spring, a team of nearly 1,000 cosmologists announced that dark energy — the enigmatic agent propelling the universe to swell in size at an ever-increasing rate — might be slackening. The ...
