But there are several important anomalies, including a widely debated one called the Hubble tension. It is named after Edwin ...

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to be true.

Our understanding of the true nature of the cosmos relies on measurements of its expansion, but cosmologists have been ...

In this video, we explore how gravitational waves from the Cosmic Microwave Background (CMB) could illuminate the mysteries of the Big Bang. The discussion includes the CMB and its polarization, ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, ...

Astronomers are closing in on a result so statistically secure that, in their language, it borders on certainty: a 99.9999999 ...

Oxygen detected just 300 million years after the Big Bang has caused viral claims that cosmology is wrong. But does this ...

Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean ...
