Thoughts On Dark Matter Search
A filament of dark matter has been directly detected between the galaxy clusters Abell 222 and Abell 223. The blue shading and yellow contour lines represent the density of matter. Image credit: Jörg Dietrich, U-M Department of Physics In light of direction LHC is experiencing there is always the questions of Oversight in terms…

Fermi Provides Insights?
[youtube http://www.youtube.com/watch?v=im-V5O0QDhI%5D There’s more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. Yet, despite decades of effort, no one knows what…

Brian Greene: Why is our universe fine-tuned for life?
At the heart of modern cosmology is a mystery: Why does our universe appear so exquisitely tuned to create the conditions necessary for life? In this tour de force tour of some of science’s biggest new discoveries, Brian Greene shows how the mind-boggling idea of a multiverse may hold the answer to the riddle. Brian…

Do Gamma rays hint at dark matter?
Using a new statistical technique to analyse publicly available data from NASA’s Fermi Space Telescope, an astrophysicist in Germany says he may have spotted a tell-tale sign of exotic particles annihilating within the Milky Way. If proved to be real, this “gamma-ray line” would, he claims, be a “smoking-gun signature” of dark matter. There is…

A Mysterious Dark Flow?
Dark flow is an astrophysical term describing a peculiar velocity of galaxy clusters. The actual measured velocity is the sum of the velocity predicted by Hubble’s Law plus a small and unexplained (or dark) velocity flowing in a common direction. According to standard cosmological models, the motion of galaxy clusters with respect to the cosmic…

The Chicagoland Observatory for Underground Particle Physics (COUPP)
The Chicagoland Observatory for Underground Particle Physics (COUPP) collaboration looks for bubbles in chambers filled with a compound containing carbon, fluorine and iodine. The fluid is superheated beyond the boiling point but has no rough surface to form bubbles. When a specific type of particle interacts in the chamber, it can deposit enough energy to…

Scientists Have Found Unexplained Force?
Both radio observations with the VLBA and optical observations with the Hubble Space Telescope have measured the motions of concentrations of material in M87’s jets, and have shown the material to be moving at apparent speeds greater than that of light. This “superluminal” motion is a geometric illusion created by material moving nearly, but under,…

Lighting up the dark universe
The CHASE detector. The end of the magnet (orange) can be seen on the right. Exploring our dark universe is often the domain of extreme physics. Traces of dark matter particles are searched for by huge neutrino telescopes located underwater or under Antarctic ice, by scientists at powerful particle colliders, and deep underground. Clues to…
