Evidence Of Dark Matter In WIMP Experiment
2013-04-16 09:16:50

An international collaboration of scientists has, for the first time, observed a concrete hint of a WIMP – weakly interacting massive particle – which physicists believe could be behind the mysterious phenomenon of dark matter.

Evidence That Dark Matter Is Real

For decades scientists have wondered whether a mysterious form of matter – known simply as Dark Matter since it does not interact directly with light – makes up the majority of the “stuff” in the Universe.

As we search the heavens, one of the striking observations is that we are constantly bombarded by a stream of extremely high energy charged particles, traveling at nearly the speed of light.

According to a new study, black hole cosmic radiation blasted into the Earth back in the 8th century. Japanese astrophysicist Fusa Miyake discovered last year clues for the strange event located in the rings of ancient cedar trees that dated back to either 774 or 775 AD.

Fermi Telescope Turns to Dark Matter Search

NASA’s Fermi Gamma-ray Space Telescope, the most advanced space-based gamma-ray mission ever launched is turnings its eye to the problem of dark matter.

Scientists Deduce Contents Of Cosmic Mystery Box
2013-01-01 10:16:02

Science teachers in grade school sometimes hand out "mystery boxes," which contain ramps, barriers and a loose marble. Rotating the marble and feeling it hang up or drop, the students begin to deduce the contents of the box.

Dark Matter Detector Gets Helping Hand From Livermore Team
2012-11-16 05:58:38

Nearly a mile underground beneath the Black Hills of South Dakota, scientists from Lawrence Livermore National Laboratory (LLNL) are using a tank to make key contributions to a physics experiment that will look for one of nature's most elusive particles, "dark matter."

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...
