In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

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

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

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and ...

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

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 ...

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 ...

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it assumes about 70 percent of the cosmos is filled with an unseen force ...

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 ...

The universe's expansion may be accelerating faster than previously thought. Dark energy, a mysterious force, might not be constant but could be changing over time. Multiple independent studies show ...

David Weinberg receives funding from the National Science Foundation and NASA that supports his dark energy research. Ashley Ross receives funding from Lawrence Berkeley National Lab to support his ...
