A new theoretical study proposes that light from distant galaxies could be slightly shifted in color by interactions with ...

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...

Very early dark energy (vEDE) may have accelerated the universe’s expansion just 380,000 years after the Big Bang, new ...

Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move ...

Dark energy and black holes are two of the most mysterious topics when it comes to space, but they might actually be linked.

According to the model, dark matter may have started as particles that were hot, light, massless, and fast. As the universe cooled, these particles became heavy, slow, and dark, becoming an invisible ...

Astronomers have unveiled a new catalog of massive galaxy clusters, revealing new insight on the evolution of the universe ...

The energy trapped inside the black hole would then bounce outwards in a burst of expansion to form a new universe. Graphical ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

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 ...
