Gravitational Waves

Gravitational wave detectors could soon uncover hints of new physics from exotic compact objects.

Space.com caught up with Greene to discuss the importance of science education, why black holes are so interesting and whether a "theory of everything" breakthrough could be on the horizon.

A team has offered a way for gravitational wave events called dark sirens to resolve a crisis in cosmology

In 2017, astronomers witnessed the birth of a black hole for the first time.

What if one mission could study the gravitational ripples triggered by some of the most violent events in the universe — on the way to observing the least-known planets of our solar system?

Astronomers may be getting closer to discovering as-yet hidden cosmic secrets, such as the nature of dark matter and the presence of widespread distortions in space-time.

A team of physicists recently used a string-theory technique to reveal that we're on the cusp of detecting phase transitions in the early universe through their gravitational wave signature.

Scientists can now catch gravitational waves better than ever before.

For black holes, a collision doesn't have to be a once-in-a-lifetime experience, new research suggests.

A new sound has joined the symphony of the universe as we hear it.

Some patience will be needed.

Scientists may one day detect alien planets outside the Milky Way using the ripples in space and time known as gravitational waves, a new study finds.

Astronomers have found a way to pinpoint our solar system's center of mass to within a mere 330 feet (100 meters), a recent study reports.

Quantum effects are pushing us around all the time, and we now have observational evidence of this somewhat disconcerting fact.

It's right there in the name: black holes aren't supposed to produce flashes of light. But scientists think that last year, they spotted black holes doing just that.

Astrophysicists have spotted the strangest gravitational-wave signal yet, an observation that could force scientists to rewrite what they know about the cosmos.

Using gravitational waves to approximate pi, physicists see no problem with Einstein's theory of general relativity.
