Hints of "dark matter"?

Is Fermi Seeing Dark Matter?

A new analysis showing a cloud of high-energy particles hovering around the center of the Milky Way could be the signature of dark matter and evidence of a “dark force”, but not everyone is convinced.

Detecting Dark Matter

Dark matter was discovered 80 years ago when astronomer Fritz Zwicky spied a galaxy cluster whirling so fast, the galaxies were bound to fly apart unless something — something less luminous than ordinary stars or gas — held them together. Decades later, the scientific community concedes the existence of dark matter, after many different kinds…

Homing in on Dark Matter

Three potential detections from deep underground could be from dark matter particles. While still uncertain, the result suggests a particle mass in keeping with hints from several other experiments.

Does a Fifth Force Permeate the Universe?

A team of theoretical physicists thinks a fifth force could explain an anomaly spotted in a nuclear physics experiment. If true, it could have huge ramifications for particle physics and dark matter — but that’s a pretty big if.
