A new study casts doubt on the universe’s accelerating expansion, suggesting dark energy might be weakening over time.

Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his ...

The mysterious force called Dark Energy, which helps the Universe to expand, might be changing in a way that challenges our ...

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 ...

Astronomers have long puzzled over the cause of a mysterious “glow” of very high energy gamma radiation emanating from the ...

Recent findings suggest a potential shift in our understanding of the universe’s expansion. After decades of acceleration, ...

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 ...

An artist’s concept of the dark energy-driven accelerating expansion of the universe. New results suggest dark energy’s influence on cosmic expansion has weakened over time. In 2024 a shockwave ...

Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought.See an excerpt of an interview in the video aboveAstronomers know ...
