Unlike for dark matter, scientists have no plausible explanation for dark energy. According to one idea, dark energy is a ...

The jury is out as to whether dark energy is best described by a cosmological constant or as dynamical. This Perspective presents both sides of the case and considers the questions that need to be ...

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 ...

For a while now, there has been a problematic mystery at the heart of the standard cosmological model. Although all observations support the expanding universe model, observations of the early period ...

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 ...

Using the LUX-ZEPLIN experiment, scientists may have detected the first direct evidence of dark matter, in the form of a rare ...

For decades, astronomers have believed that dark matter and dark energy make up most of the universe, however, a new study suggests they might not exist at all. Instead, what we perceive as dark ...
