The local universe may be expanding more slowly than previously thought, a discovery that could relieve a pesky discrepancy ...

Between May 2023 and January 2024, a global network of gravitational-wave detectors picked up 128 new cosmic signals, more ...

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 ...

A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the ...

Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other birthing space and time. A provocative line of research now suggests those ...

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 ...

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

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...

There was, you might say, a disturbance in the Force. Long, long ago, when the universe was only about 100,000 years old — a buzzing, expanding mass of particles and radiation — a strange new energy ...
