Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

Primordial magnetic fields may help explain why measurements of the universe’s expansion do not agree. Scientists have long known that the universe is expanding, yet there is still no agreement on how ...

Dark matter is thought to exist everywhere, wrapping around galaxies and helping to shape the largest things in the universe.

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 ...

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 ...

Most current models of the Big Bang rely on general relativity along with additional elements that are introduced to make the theory fit observations. In contrast, this new framework provides a more ...

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to be true. Space is stretching faster today than in the past, and the precise ...

Cousins says he is “hopeful” that the findings of gravitational-wave cosmology will be able shed more light on the Hubble ...

Scientists have made a new calculation of the speed at which the universe is expanding, using the data taken by the powerful new James Webb Space Telescope on multiple galaxies. Above, Webb’s image of ...

A new study has found that a hidden bias in galaxy models can skew gravitational-wave measurements of how fast the universe is expanding. That finding complicates one of astronomy’s most promising ...

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 ...
