Dark Matter

The Nobel Prize in physics this year has gone to two very different research threads — and danced around some big societal issues, even as they celebrate distinguished work.

Physicists have proposed that a trio of particles called Higgs bosons could be responsible for the mysterious vanishing act of antimatter in the universe.

Two theoretical physicists propose a novel idea to find dark matter — and it might actually be testable.

Physicists on the hunt for the invisible hand that shapes our universe and the galaxies within it have turned their gaze to the dark side.

An experiment to seek out dark energy, or the so-called "fifth force," has come up empty-handed, casting doubt over some theories related to the mysterious cosmic matter.

Cracking the mystery of dark matter is one of the most frustrating quests of physics.

Nobody has stumbled into an emergency room with an inexplicable lightsaber wound, as far as we know — and that tells us something about dark matter, a new study suggests.

The secrets of the universe are so important that NASA plans spacewalk work to fix a dark matter experiment on the space station, said U.S. astronaut Jessica Meir.

There are voids in the universe, and we can't see them properly. But the good news is that astronomers just got much better at not seeing them properly.

Tiny ripples called magnons could lure even a fleeting, lightweight dark matter particle out of hiding.

We can't see it. It might not be made of normal matter. Our telescopes haven't directly detected it at all. But it sure seems like it's out there.

The Large Hadron Collider should be able to detect these rare particles — if they exist.

These particles would be much tinier than electrons.

Here's how the biggest thing in the universe could reveal secrets of the smallest things.

We now have a better idea of how big black holes were born in the early universe, a new study reports.

Before the Big Bang, time may have run in reverse.

These tiny subatomic particles, showering down from the depths of space, continue to surprise (and annoy) physicists chasing them.

Astronomers barely know anything about dark matter, but now they know this: It behaves differently in old, dying galaxies than in new, star-forming ones.
