Dark matter is one of the most puzzling mysteries of science, with a huge range of suspects being investigated. In a new study, astronomers have searched for clouds of hypothetical, ultralight ...

Gravitational wave astronomy is starting to do more than confirm Einstein’s equations. It is turning into a precision tool ...

A new type of gravitational wave detector running in Western Australia has recorded two rare events that might be signals of dark matter or primordial black holes. These high-frequency gravitational ...

Gravitational astronomy is a relatively new discipline that has opened many doors for astronomers to understand how the huge and violent end of the scale works. It has been used to map out merging ...

Scientists think that, under some circumstances, dark matter could generate powerful enough gravitational waves for equipment like LIGO to detect. In 1916, Albert Einstein published his theory of ...

For decades now, the exact composition of matter in the universe has baffled astronomers and physicists alike. It would seem that, given the basic assumptions about the origins of the universe, there ...

Observations of gravitational waves from merging black holes may unveil the true nature of dark matter, according to new research. The announcement last week of the discovery of the gravitational wave ...

When two sufficiently massive objects collide — such as when two black holes merge — the forces can actually bend space-time, creating ripples called gravitational waves. These gravitational waves can ...

One of the biggest puzzles in modern cosmology is the existence of dark matter, which constitutes most of the matter in the universe. Recent research by an international team of researchers has used ...

Dark matter could consist of particles so ultralight, they behave more like waves. Although the motions of galaxies provide evidence that dark matter exists, scientists have yet to directly detect the ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

Gravitational waves from black holes may soon reveal where dark matter is hiding. A new model shows how dark matter surrounding massive black holes leaves detectable fingerprints in the waves recorded ...
