Independent scientists have cast serious doubt on a claimed detection of dark matter.
Whisper From the First Stars Sets Off Loud Dark Matter Debate
A surprise discovery announced a month ago suggested that the early universe looked very different than previously believed. Initial theories that the discrepancy was due to dark matter have come under fire.
A Victory for Dark Matter in a Galaxy Without Any
Paradoxically, a small galaxy that seems to contain none of the invisible stuff known as “dark matter” may help prove that it exists.
Neutron Lifetime Puzzle Deepens, but No Dark Matter Seen
Two methods of measuring the neutron's longevity give different answers, creating uncertainty in cosmological models. But no one has a clue what the problem is.
Deathblow Dealt to Dark Matter Disks
New data tracking the movements of millions of Milky Way stars have effectively ruled out the presence of a “dark disk” that could have offered important clues to the mystery of dark matter.
Galactic Glow, Thought to Be Dark Matter, Now Hints at Hidden Pulsars
A number of high-energy anomalies raised hopes that astrophysicists had seen their first direct glimpses of dark matter. New studies suggest a different source may be responsible.
