Gravitational Waves

The earliest and most momentous epoch in the history of the universe released a flood of gravitational waves, tiny ripples in the fabric of space-time.

Scientists hunting for elusive gravitational waves across the universe may be able to supercharge their discoveries with a new tool: artificial intelligence.

After more than four years of exploring a menagerie of cosmic happenings through gravitational waves, scientists have finally spotted the third expected variety of collision — twice.

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.
