Dark Matter

This month marks the 10th anniversary of the discovery of the Higgs boson. But what exactly is this particle, and why is it so important? What has it taught us in the last decade – and more importantly, what could it teach us in the next decade?

The world’s most sensitive dark matter detector is ready to tackle one of the most perplexing mysteries of the universe. Over 50 times more sensitive than others, LUX-ZEPLIN lurks quietly a mile underground, waiting for these hypothetical particles.

Although it should be extremely common in the universe, dark matter has proven tricky to detect. Now researchers have proposed an intriguing new method to spot it – looking for shock waves as dark matter “asteroids” collide with stars.

A huge range of dark matter suspects are being investigated. In a new study, astronomers have searched for clouds of hypothetical ultralight particles that could congregate around black holes, and reveal themselves by sending out gravitational waves.

How did the universe end up with exactly the amount of dark matter needed? A new model suggests dark matter particles in the early universe converted regular matter into dark matter exponentially, before being slowed by the expansion of the universe.

Physicists have measured the lifetime of a free neutron more precisely than ever before. This breakthrough "bathtub" experiment helps probe the fringes of the Standard Model of particle physics, and mysteries like dark matter and the early universe.

Last year, physicists reported that an experimental dark matter detector picked up a strange signal. A new Cambridge study suggests it could be the first direct detection of dark energy, the mysterious force accelerating the expansion of the universe.

A new type of gravitational wave detector has recorded two rare events that may be signals of dark matter or primordial black holes. These high-frequency gravitational waves are beyond the range of most detectors and have never been recorded before.

Dark matter should be all around us, but the stuff is frustratingly elusive. Now physicists at NIST have developed a new sensor that could help us detect certain hypothetical dark matter particles, using a two-dimensional quantum crystal.

Space is an exceptionally strange place, full of signals and observations that defy our understanding of the universe. In trying to explain these mysteries, sometimes astronomers hypothesize extremely exotic objects that we haven’t yet found.

In 2018 astronomers claimed to have found a galaxy that didn’t have any dark matter. The controversial study sparked a debate and raised new questions about cosmology. Now, the scientists say they've uncovered further evidence of the odd deficiency.

Supermassive black holes are thought to grow slowly over billions of years – but how did they appear so early in the universe’s lifetime? A new origin story suggests black hole seeds were created by halos of self-interacting dark matter collapsing.
