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

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Two metal devices with blue lights at their necks are pointed up toward the sky. In the sky, there are lots of stars and the ...

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: ...

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 ...

What if the Universe were not symmetrical? This idea, which goes against what scientists have long believed, emerges from new studies on large cosmic structures. Instead of being uniform in ...
