Dark Matter

How much dark matter has gone missing since the Big Bang? New research suggests anywhere from 2 to 5 percent.

A non-discovery is causing physicists to rethink how they think about dark matter, the mysterious "stuff" that pervades the universe.

Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests.

Computer simulations suggest that filaments of invisible dark matter form long "hairs" when they go through planets such as Earth.

Dark matter particles may have interacted often with normal matter long ago, when the universe was very hot, a new study suggests.

Dark matter might be made of clouds of energy cracks instead of particles and may be detectable in GPS signals.

The mysterious matter called dark matter may not be made of tiny particles, as most scientists believe, but instead may consist of chunks as large as an asteroid, researchers say.

The AMS particle detector aboard the International Space Station has found more evidence of dark matter in cosmic ray data.
