A new dark energy model suggests the universe may eventually stop expanding and collapse in a giant Big Crunch.

A new set of cosmological studies is raising questions about one of the deepest assumptions in modern physics: the idea that ...

The most precise measurement of the expansion rate ever made suggests an unknown force may be affecting the universe.

An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be straightforward. Objects are still emitting light, and that light takes time to travel ...

The universe is expanding 'too fast', a study has warned – and scientists have no idea why. An international team of astronomers have carried out some of the most precise measurements yet of how ...

A major international effort has produced an ultra-precise measurement of the Universe’s expansion rate, confirming it’s faster than early-Universe models predict. By linking multiple ...

Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still don’t add up, they say. Reading time 3 minutes One major, unsolved problem ...
