A comprehensive new study combines decades of research to reveal that we're missing an essential component in our ...

A major international effort has produced an ultra-precise measurement of the Universe’s expansion rate, confirming it’s ...

In A Nutshell A 37-member international team produced the most precise direct measurement of the Hubble constant ever recorded, with just 1.1 percent uncertainty. By linking a dozen different cosmic ...

‘Cosmic fossils’ left by black holes created before the big bang may still shape the universe - Universe may have been ...

(via PBS Space Time) We've known that the universe is expanding since 1929, and that its expansion is accelerating since 1998. The culprit behind the acceleration is unknown, so we live with a ...

New measurement deepens Hubble Tension, suggesting the Universe may be expanding faster and hinting at unknown physics.

The universe expands faster. “Dark energy” may not be constant after all. We’ve known since 1929 that the universe is expanding, and since 1998 that it’s speeding up. The unknown force behind this ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to be true. Space is stretching faster today than in the past, and the precise ...

Since humanity's earliest days, people have looked up at the stars, using science, art, religion, philosophy, mathematics, and any other tool at their disposal to better understand the complicated and ...

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could ...

Black holes that formed before the Big Bang could still exist today as ‘cosmic fossils’, potentially helping to explain the ...
