The solar system is moving through space over three times as fast as estimated, calling into question our best model of the universe and its evolution.

Something appears amiss in cosmology. A tension has arisen from attempts to measure the universe’s current expansion rate, known as the Hubble constant. Large international teams have used two general ...

Astronomers determined in 1929 that the universe is expanding. This was one of the most important findings in science. In 1998, two separate groups of astrophysicists discovered that the universe’s ...
