Dark Matter

A model of exotic dark matter suggests that the first stars may have formed not as individuals, but as tiny pockets embedded in gigantic, pancake-like sheets.

Meteor-hunting methods could be adapted to hunt for dark matter, the mysterious substance that makes up around 85% of the universe's matter but remains invisible.

Two decades' worth of observations of supernova explosions and a powerful new analysis tool has provided the most accurate accounting of dark energy and dark matter to date.

A machine-learning algorithm has helped astronomers discover thousands of gravitational lenses predicted by Einstein.

One hypothesis for the nature of dark matter is that some of it could be self-interacting, meaning the individual particles interact slightly with one another.

Scientists think that when dark photons collect around black holes, they can get trapped and boosted to high energies, where they might transform into other particles (or even just normal photons).

It's true that the dark matter hypothesis has its shortcomings — and, of course, we haven't found any dark matter particles yet. But the truth is that the alternatives are much worse.

A new hypothesis proposes that a large fraction of dark matter may be bound up inside tight balls the size of Neptune — so-called dark matter planets.

Using a cosmic relic from the universe's earliest moments researchers have made the earliest detection of a mysterious form of matter that makes up 85% of the universe's mass.

Observations across a vast range of scales are much better explained in an alternative theory of gravity requiring no invisible matter.

The LUX-ZEPLIN experiment has delivered its first results which show it to be the most sensitive dark matter detector to date.

With the switching back on after a three-year hiatus, CERN's Large Hadron Collider turns its sights toward shedding light on the mysterious dark matter.

More than 50 years since astronomers first proposed "dark matter," we have no idea what it is and nobody has directly seen it or produced it in the lab.

The newly-upgraded Large Hadron Collider just broke a world record with its proton beams.

Did the graviton, the quantum mechanical force carrier of gravity, flood the cosmos with dark matter before normal matter even had a chance to get started?

A mirror universe that runs backward in time sprouted up before the Big Bang.

Though scientists know there's a supermassive black hole at the center of most galaxies, they can't explain how the gravitational giants formed.

Scientists investigating the true identity of dark matter are finding new evidence to support one leading candidate: axions.

CERN will not enter new cooperations with Russian scientific institutions following a request of Ukraine's scientists to halt partnerships with Russian science institutions.

Scientists are gearing up to once more push the boundaries of the cutting edge of particle physics with the reopening of the Large Hadron Collider (LHC) at CERN after a three-year shutdown.
