The research suggests that the universe has become “messier and more complicated” over time, with a less clumpy distribution of matter.

A "cosmic CT scan" performed by scientists using two very different cosmic surveys has revealed the cosmos is less clumpy and ...

One could argue that cosmologists had made little progress in our understanding of these basic facts since the discovery of the cosmic microwave ... be due to the background energy associated ...

Across cosmic history, powerful forces have acted on matter, reshaping the universe into an increasingly complex web of ...

By employing a new and improved supercollider, scientists are hoping to dissect the very fabric of the Universe and calculate ...

As the universe expanded, the material cooled, condensing after ~400,000 years into neutral atoms, freeing the cosmic microwave background (CMB). Fifty million years or so later ... and dark matter ...

"Formally, this light is called the Cosmic Microwave Background (CMB), but we sometimes ... photons to shift to longer wavelengths and lose energy. Its temperature is now uniform at minus 454 ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.
