Our best model of the cosmos has a glaring mathematical problem, but we may have found an answer.

The new study used the known distance to a galaxy called M106/NGC 4258 — a spiral galaxy in the constellation Canes Venatici — as a reference point. The universe is expanding faster than astronomers ...

Astronomers have known for a century that the universe is expanding. We can now trace this expansion over much of its almost 14 billion year history, with important constraints going back to just one ...

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 ...
