AUSTIN (KXAN) — A commonly held belief that the universe is rapidly expanding may be wrong. A new paper published this month suggests the universe’s expansion might be slowing down and it could mean ...

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

For almost a century, we have known that the universe is expanding. For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates were the ...

Using gravitational waves as a measure of the universe's rate of expansion could solve the biggest headache in physics, the so-called "Hubble tension." ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests. Subscribe to our newsletter for the latest ...

The universe is expanding faster than previously thought, according to a team of astronomers using the Hubble Telescope. How much faster? Five to nine percent faster. Initially the expansion of the ...

The universe isn’t just growing—it’s speeding up as it does. That discovery stunned scientists, upending long-held ideas about gravity and motion in space. This rapid expansion wasn’t predicted by ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown.

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...
