Scientists Reformulate Their Knowledge Of Dark Matter
2014-07-04 09:21:15

For decades, the mystery of Dark Matter has been at the forefront of physics research. Since the 1930s, scientists have been aware that all of the mass that we can see – the stars, the dust, the planets, and black holes – makes up only 20 percent of the Universe.

Syracuse University Plays Key Role In Search For Elusive Dark Matter
2014-04-11 13:31:00

Physicist Richard Schnee hopes to find traces of dark matter by studying particles with low masses and interaction rates, some of which have never been probed before

Dark Matter Clues From The Center Of Our Galaxy
2014-04-03 13:57:46

A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe.

Dark Matter Results From LUX Confirmed After Recalibration - WIMPs Still Not Detected
2014-02-21 08:47:17

Dark matter research, like all experiments involving particle and astrophysical detections, relies on sorting out the desired events (the source events) from the noise (the background events). Since the interactions occur at a quantum level, the statistical process of sorting through the data is laborious, but also, more importantly, relies on your ability to calibrate and understand the instrument.

Pamela Fleming, Executive Secretary of the Institute for Basic Research, Florida, announces the apparent detection of antimatter galaxies, antimatter asteroids and antimatter cosmic rays by the

Lead Ingots From Shipwrecks Being Used To Hunt For Dark Matter
2013-12-02 08:18:12

Albeit with much controversy, physicists are using ancient lead ingots from sunken ships in the study of dark matter in neutrinos. Archaeologists have gone on the offensive, expressing concerns over the destruction of underwater cultural heritage.

Axion Search For Dark Matter
2013-11-07 08:36:41

A research team is hunting for a theorized but never-before-seen elementary particle called an axion that may be at the heart of dark matter.

LUX Dark Matter Detector Finds Nothing Yet
2013-10-30 13:49:42

Just three months into its operation, the Large Underground Xenon experiment is already the most sensitive dark matter detector in the world.

Experiment Looks For Dark Matter Particle
2013-10-29 08:16:46

MIT physicists have proposed a new experiment to look for the elusive dark matter particle known as the 'A Prime' particle.

Space Weather Impacts Pilots And Airline Passengers

WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...

Cosmic Rays -- Cosmic Rays. Cosmic rays are energetic particles that are found in space and filter through our atmosphere. Cosmic rays have interested scientists for many different reasons. They come from all directions in space, and the origination of many of these cosmic rays is unknown. Cosmic rays were originally discovered because of the ionozation they produce in our atmosphere. Cosmic rays also have an extreme energy range of incident particles, which have allowed physicists to...
