A new study argues that dark matter and dark energy might be illusions caused by the universe’s forces fading over time. For many years, scientists have thought that dark matter and dark energy make ...

A controversial prediction about black holes and the expansion force of the universe could explain a cosmology mystery ...

The story begins with the black hole information paradox. According to relativity, anything that falls into a black hole is ...

Ask most astronomers, and they'll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...

Black holes are eaters of all things, even radiation. A new study published in Physical Review Letters suggests that black ...

Evolving dark matter may explain cosmic acceleration. Observations support a mixed model. For years, a stubborn puzzle has sat at the center of the standard cosmological model. The evidence clearly ...

Since the early 20th century, scientists have gathered compelling evidence that the universe is expanding at an accelerating ...

Researchers propose that black holes may emit dark energy, possibly explaining the universe's accelerating expansion.

Einstein’s version of dark energy is known as the cosmological constant. It implies a fixed amount of dark energy in each ...

A new research paper authored by Shajib challenges a long-standing assumption about the nature of dark energy.

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 ...
