Welcome to the age of precision cosmology, a scientific era in which astronomers and physicists have measured almost everything about our universe—except for its deepest mysteries: dark matter and ...

In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery birth like the Big Bang, this idea suggests the cosmos has been growing in ...

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a ...

For decades, astronomers have believed that dark matter and dark energy make up most of the universe, however, a new study suggests they might not exist at all. Instead, what we perceive as dark ...

New research suggests dark matter could leave a tiny but discernible imprint in the cacophony of ripples in spacetime called "gravitational waves" that ring through the cosmos whe ...

"The new model can account for both structure formation and stability, and the key observational properties of the expansion of the universe at large." When you purchase through links on our site, we ...

Dark energy has been a mysterious element of cosmological equation since it was proposed three decades ago, but new research ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Subscribe to our newsletter for the latest ...

NASA's latest and greatest space telescope, named after the agency's first female chief astronomer Nancy Grace Roman, is ...

When an invisible entity making up 85% of the universe's mass stumps the greatest scientific minds of our time, awe is an understandable response.

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely interact with the rest of the universe via gravity and to serve as the ...
