The Universe is expanding faster than predicted by theoretical models, and faster than can be explained by our current understanding of physics. This discrepancy between model and data became ...

that our model of cosmology might be broken." There are two gold-standard methods for working out the Hubble constant — the value that quantifies the speed of the universe's expansion.

A new way to study 3D maps of galaxies in the cosmos without compressing the data is revealing new information about the dark ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

When they use nearby objects like supernovae and galaxies to measure this expansion, they find the universe is stretching at about ... the afterglow of the Big Bang — along with our standard model of ...

The standard model of cosmology is the growth curve ... which essentially means that the local universe is expanding 76.5 kilometers per second faster every 3.26 million light-years.

The model isn't perfect. It still assumes something about the early universe — namely, that the cosmological constant is strong enough to lead to a rapidly expanding cosmos. And it doesn't ...

This assumption underpins the need for dark energy to explain the universe's expansion. However, Lane and his colleagues tested an alternative idea called the timescape model, which suggests that ...
