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

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

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

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 ...

The standard cosmological model (present-day version of "Big Bang," called Lambda-CDM) gives an age of the universe close to 13.8 billion years and much younger when we explore the universe at ...

Assumptions that physicists have made about the universe for over a century may be about to be overturned. Evidence is emerging that it is far lumpier than we had thought – a finding that could solve ...

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing ...
