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 ...

(Nanowerk News) An international collaboration of astronomers has produced one of the most precise measurements yet of how fast the local Universe is expanding. The result deepens one of the most ...

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 ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

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 ...

It is widely thought that our universe is expanding at an ever-accelerating rate. But could we have that wrong? That is what a group of scientists from South Korea claims, but other scientists have ...

Artist’s interpretation of the cosmic distance ladder — a succession of overlapping methods used to measure distances across the Universe, where each rung of the ladder provides information that can ...

Schematic of the expansion of the universe from the big bang (starting on the left side) to the present day. We have known for several decades that the universe is expanding. Scientists use multiple ...
