Astronomers Are Baffled To Find That the Universe Is Expanding Too Fast; 'Not What We Expected' Astronomers routinely ...

The clearest and most precise images yet of the universe in its infancy—the earliest cosmic time accessible to humans—have ...

The Hubble constant is one of the most important numbers in cosmology because it tells us how fast the universe is expanding, which can be used to determine the age of the universe and its history. It ...

After five years of staring unblinking at the sky, the Atacama Cosmology Telescope (ACT) has compiled the most detailed map ...

Dark energy is a mystery so daunting that it stretches and strains our most robust theories. The universe is expanding, ...

New data further challenge the best scientific theory of the history and the structure of the universe. But a separate recent ...

Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.

The finest ever map of the cosmic microwave background - the faint evidence of the universe's early form - has yielded ...

a number known as the Hubble constant. Probes of the distant, early universe seem to be giving estimates significantly lower ...

Or, more precisely, astronomers have used multiple methods of estimating the Hubble constant, and the different methods are converging quite tightly on two different values! This clearly can’t ...
