For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

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 ...

A scientist from Tokyo Metropolitan University has solved the longstanding problem of a "dissonance" in gravitational waves emitted by a black hole. Using high precision computing and a new ...

The universe is expanding—that much is clear. The rate at which it expands is a bone of contention among scientists. The so-called Hubble constant accurately predicts how fast objects recede, but it's ...

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...

Our universe would look so different, Kyle. You might not recognize it even if you could be here to see it. Unfortunately, there probably wouldn’t be a whole lot to see. I learned about this from ...
