Is it possible to understand the universe without understanding the largest structures that reside in it? In principle, not ...

A collaboration between Nordita, the Nordic Institute for Theoretical Physics, hosted by Stockholm University, KTH and Google Quantum AI explores how gravitational fields influence quantum computing ...

The merger of black holes is intrinsically linked to the emission of gravitational waves. Once black holes are close enough ...

ABSTRACT: The Newtonian gravitational constant G is one of the most important fundamental constants of nature, but still remains resistant to the standard model of physics and disconnected from ...

Putting it all together, we're left with a model of an expanding cosmos that is dotted fairly evenly with slow clumps of matter we can see and some we can't, pushed predictably apart at an estimated ...

Ellie Cook is a Newsweek security and defense reporter based in London, U.K. Her work focuses largely on the Russia-Ukraine war, the U.S. military, weapons systems and emerging technology.

Rather than relying on a cheek swab or a little blood, however, these cosmic DNA tests utilize tiny ripples in the fabric of spacetime called gravitational waves, first proposed by Albert Einstein ...

Since Edwin Hubble’s 1929 discovery that the Universe is expanding, determining the precise rate of this expansion — called the Hubble constant — has been a cornerstone of cosmological research.

Instead, it proposes a novel mechanism that suggests that inflation arises from gravitational wave amplification. Inflation is believed to have laid the foundation of everything there is out in space.

Gravitational waves on their own can't form ... that the cosmological constant is strong enough to lead to a rapidly expanding cosmos. And it doesn't explain the flatness problem or why distant ...

Six planets grace the sky this month in what's known as a planetary parade, and most can be seen with the naked eye. These planetary hangouts happen when several planets appear to line up in the ...
