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 ...

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 ...

Cosmologists are finally beginning to sketch a coherent picture of the universe we cannot see, using exquisitely detailed ...

In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery birth like the Big Bang, this idea suggests the cosmos has been growing in ...

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 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 ...

As the Vera C. Rubin Observatory surveys the night sky, astrophysicists expect to unlock the secrets of dark matter, dark energy and cosmic phenomena that go “bang!” The telescope mount assembly ...

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 ...

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 ...

Florian Neukart does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond ...

By studying faint distortions in galaxy shapes across a vast region of sky, scientists probed the hidden structure of the universe. In the standard picture of the universe, nearly everything is hidden ...

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 ...
