Mysterious Galactic Signal Points LHC To Dark Matter
It is one of the most disputed observations in physics. But an explanation may be in sight for a mysterious excess of high-energy photons at the centre of the Milky Way. The latest analysis suggests t...
Astrophysicists Draw Most Comprehensive Map Of The Universe
Astrophysicists have created a 3D map of the universe that spans nearly two billion light years and is the most complete picture of our cosmic neighbourhood to date. The spherical map of galaxy superc...
Dark matter map unveils first results
Dark matter is the invisible "web" that holds galaxies together; by watching how clumps of it shift over time, scientists hope eventually to quantify dark energy - the even more mysterious force that ...
Dark Matter Just Got Darker
Dark matter: unless you're a theoretical physicist, you're probably will have a hard time explaining just what this mysterious thing in our Universe really is. Even experts have long viewed the materi...
Theory Explains Dark Matter By Finding A Link Between Quantum Mechanics And General Relativity
A new theory developed by Lic. Stuart Marongwe of the McConnell College in Botswana takes a quantum theory approach to general relativity and explains the existence of both dark matter and dark energy...
Dark matter guides growth of supermassive black holes
A winner has been declared in the debate about stars, dark matter and black holes, and it can help us understand how elliptical galaxies grow.
Does dark matter cause mass extinctions and geologic upheavals?
As our planet travels through the Milky Way, Dark Matter may Be responsible for cosmic upheaval which led to mass extinctions.
New version of the Large Hadron Collider aims to solve some of the even deeper mysteries of the universe
The world's biggest particle collider, CERN's Large Hadron Collider, located near Geneva, has been undergoing a two-year refit. In 2012, the collider confirmed existence of the Higgs boson particle.
Dark matter
Dark matter is a hypothetical kind of matter that cannot be seen with telescopes but accounts for most of the matter in the Universe. The existence and properties of dark matter are inferred from its ...

In astrophysics and physical cosmology the mass to light ratio, normally designated with the symbol is the quotient between the total mass of a spatial volume (typically on the scales of a galaxy or ...
Dark galaxy
A dark galaxy is a hypothetical galaxy composed of dark matter. Dark galaxies receive their name because they have no detectable stars and are theoretically invisible. They are not able to generate st...
Dark matter in fiction
Dark matter is defined as hypothetical matter that is undetectable by its emitted radiation, but whose presence can be inferred from gravitational effects on visible matter. It has been used in a vari...
