For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the ...

Dark energy may be the most mysterious substance ever proposed, but many scientists are certain it exists. Why?

In a new study, scientists began pondering a pretty wild question: What if black holes can convert dead star matter into dark energy, the mystery force driving the acceleration of the expansion of the ...

Researchers in Germany argue that a modified theory of gravity could explain universal expansion, removing dark energy from ...

The Standard Model of our universe doesn’t match the evidence, in part because of dark energy, a ghostly force pushing the ...

But no one knows what dark energy actually is. One suggestion is that it might be a kind of energy associated with empty space known as the “ cosmological constant,” an idea first proposed by Albert ...

Move over the James Webb Space Telescope, there’s a new kid on the block. The Vera C. Rubin Observatory, which has promised to answer questions about dark matter and energy, is finally here after an ...

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 ...

One of the greatest mysteries in cosmology is the nature of what we refer to as dark energy. This mysterious force drives the expansion of the universe to accelerate. Dark energy is an unknown ...

Exotic hypothetical particles known as axions could potentially be produced inside a nuclear reactor, something The Big Bang ...
