By studying how light from eight distant quasars is gravitationally lensed as it propagates towards Earth, astronomers have ...

New research suggests that a troubling disparity in the rate of expansion of the universe, known as the Hubble constant, may arise from the fact Earth sits in a vast underdense region of the cosmos.

One of the most stubborn issues in cosmology today concerns the universe's rate of expansion. Scientists know it's expanding, ...

The Hubble tension is one of the biggest mysteries in cosmology. It centers around the Hubble constant—the measurement of how fast our universe is expanding—which comes out as two different numbers ...

If our universe revolves around itself – and even if only very slowly – this could explain the so-called Hubble tension and thus one of the greatest mysteries of cosmology. At least that is the ...

The universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous—and highly ...
