The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from dark-energy observatories. After expanding to its peak size about 11 billion ...

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 ...

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 ...

Astronomers have studied 3,600 supernovas to discover diversity in exploding white dwarf stars, a vital tool in the ...

“It’s like doing up a shirt with the first button fastened incorrectly,” said Young-Wook Lee of Yonsei University, setting the frame for the flaw at the heart of modern cosmology. For the last three ...

Recent observational breakthroughs are beginning to challenge the long-standing view of dark energy as unchanging. Data from the Dark Energy Spectroscopic Instrument ( DESI ), an advanced survey ...

"If these results are confirmed, it would mark a major paradigm shift in cosmology since the discovery of dark energy 27 years ago." When you purchase through links on our site, we may earn an ...

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 ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction ...

A recent study by Rajendra Gupta, published in "Galaxies," proposes that cosmic phenomena conventionally ascribed to dark matter and dark energy can be explained by the temporal weakening of ...

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 ...
