The results reveal that our universe is reverberating with cosmic collisions. Some of the waves stem from pairs of black ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering ...

A closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...

Proposals offering alternatives to Einstein’s relativistic theory of gravitation are almost as old as the theory itself. Einstein even saw them as the beginning of a path that could lead to quantum ...

The loudest collision ever recorded between two black holes has allowed scientists to test Einstein’s theory of general relativity in unprecedented detail, showing that the physicist’s predictions ...

Lt. Gen. Vladimir Alekseyev provided intelligence to the Kremlin for Russia’s invasion of Ukraine and had been penalized by the U.S. twice, including for meddling in elections. By Nataliya Vasilyeva A ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

Last year, fusion power startup General Fusion was struggling to raise funds, laying off at least 25% of its staff before receiving a $22 million lifeline investment while it figured out how to keep ...

There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”. However, Lorentz invariance – the theory that the same rules of physics apply ...
