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

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an ...

A team of astronomers have found a mysterious object in the distant universe that could be dark matter or an inactive smaller ...

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 ...

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a finite timeline, new calculations suggest.

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 ...

According to the model, dark matter may have started as particles that were hot, light, massless, and fast. As the universe ...

A new model suggests the universe may stop expanding and collapse in a reverse Big Bang, ending in a Big Crunch about 20 ...

Galaxy rotation curves have been confounding astronomers for decades. Stars on the peripheries of galaxies rotate faster than visible matter can account for.

Scientists found where the universe’s missing matter went. Black holes have been pushing it far away from galaxies.

A new study published in the Journal of Cosmology and Astroparticle Physics proposes an alternative model which gives the universe an expiration date. According to this new model, everything will come ...

The Vera C. Rubin Observatory has begun its decade-long survey to scan the entire night sky every three days. To do this, it ...
