A difference of a few kilometers per second might not sound like much. In cosmology, it has become one of the field’s most ...

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 ...

The universe is expanding about 10% faster than it should be, and a fresh set of measurements just made the problem harder to ...

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

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 ...

In around 5 billion years, the sun will run out of the fuel needed for nuclear fusion in its core. This will cause its inner core to collapse under the force of the sun's own gravity. At this point, ...

Early-universe probes, including the cosmic microwave background, baryon acoustic oscillations, and the inverse distance ladder, point to lower values, about 67 to 68 km/s/Mpc. The disagreement sits ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. New findings into a cosmic puzzle suggest that scientists may have "misunderstood the universe." Astronomers know that ...

A new synthesis of astronomical measurements confirms a persistent mismatch that could point to physics beyond current models ...

The universe is stretching apart faster than our current theories of physics can explain, and a new study has just confirmed that the discrepancy is not a fluke.

The cosmic distance ladder is the world’s longest ruler, built to measure the universe. Since the time of the ancient Greeks, scientists have been constructing a cosmic measuring tape to measure the ...
