To turn that distance into a Hubble constant, you also need the event’s redshift, which is tied to how fast the source is receding due to cosmic expansion. Standard approaches get the redshift by ...

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 ...

A recent study published in Astronomy & Astrophysics has provided the most accurate measurement of the universe’s expansion rate, a discovery that not only refines our understanding of cosmology but ...

LIGO–Virgo–KAGRA, an international scientific collaboration, has announced a near doubling of the detected ripples in ...
