Dark matter observations: missed it by that much

A theory which endows dark matter particles with a rare type of electromagnetism has been strengthened by a detailed analysis performed by a pair of physicists at Vanderbilt University. Professor Robert Scherrer and post-doctoral fellow Chiu Man Ho propose that dark matter, an invisible form of matter that makes up 85 percent of the all […]

New insight into matter/antimatter conundrum




Physicists at the Fermilab Tevatron particle collider have observed that short-lived B meson particles produced from proton collisions break down into debris that includes slightly more matter than antimatter, just the sort of matter/antimatter asymmetry that could explain the prevalence of matter over antimatter in the universe. The results are being published this week in […]

Galactic Cluster Collision Sheds Light On Dark Matter




The invisible substance known as dark matter is thought to provide the additional gravitational force that stops galaxies from flying apart. Although astronomers don’t know what dark matter is made of, they hypothesize that it is a type of elementary particle that pervades the universe. Despite its profound effects throughout the universe, tracing and observing […]

The Strange Matter Of Superfluidity




In his most recent experiments into superconductivity and superfluidity, physicist Randall Hulet of Rice University looks to have recreated the same quantum conditions that may occur at the heart of quark stars; the stars that are believed to be comprised of strange matter. Hulet’s observations fly in the face of conventional theories, because he has […]

Dark Matter Takes Shape With New Map




The latest issue of Astrophysical Journal carries news of new “dark matter maps” of two young galaxies created by astrophysicists at Johns Hopkins University. Although scientists can measure the effects of invisible dark matter, its exact nature continues to be elusive. Past attempts to map dark matter in detail with ground-based telescopes have been fruitless. […]
