Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

We’re still not sure exactly what dark energy is, but it may have played a key role in the early universe. The resulting dilemma is called the Hubble tension, and Niedermann and Sloth say they may ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA’s Integral gamma-ray observatory have tried an unusual method: ...
