Dark Matter: What Is It?

December 15, 2015 | 1

All that we see and experience in a normal day is made of matter. The thing that makes up the universe and all the rest — everything on Earth, everything ever observed with all of our instruments, all normal matter — adds up to less than 5% of the Universe. More is unknown than is known. Read More

First Evidence For Rich Physics In The Dark Matter’ Sector

April 16, 2015 |

For the first time, astrophysicists may have observed the first signs of dark matter interacting — not with ordinary matter — but with itself, and not just through the pull of its gravity. Read More

New Map Reveal Distribution Of Dark Matter At Cosmic Scale

April 14, 2015 | 2

Researchers on the Dark Energy Survey have created the first map of the distribution of dark matter across the universe. Experts who created these series of maps says that these are the largest maps ever created at this level of unprecedented detail and will improve our understanding of dark matter and its role in the formation of galaxies.

Colliding Galaxy Clusters May Shed New Light on Dark Matter

March 27, 2015 |

Dark matter is one of science’s great mysteries. It makes up an enormous amount matter in the universe, it is invisible, and it does not correspond to anything in the realm of our experience. Different theories compete for an explanation, but so far none of them has prevailed. Read More

Gamma Rays from Dwarf Galaxy might Help to Explain Dark Matter

March 12, 2015 |

A promising new discovery by physicists at Carnegie Mellon and Brown and Cambridge Universities in the US could provide a step towards finally identifying the elusive substance called dark matter. Read More

Mysterious Dark Matter Influences Growth of Supermassive Black Holes

February 20, 2015 |

Dark matter and black holes are some of the most mysterious things in the Universe, so a connection between the two is absolutely thrilling. In a new study of elliptical galaxies led by Dr Akos Bogdan of the Harvard-Smithsonian Center for Astrophysics has revealed a surprising link between galaxies’ dark matter halos and their central black holes.

Dark Matter may have Caused a Massive Extinction on Earth

February 20, 2015 |

Every 250m years the sun, with its entourage of planets, completes a circuit of the Milky Way. Its journey around its home galaxy, though, is no stately peregrination. Rather, its orbit oscillates up and down through the galactic disc. It passes through that disc, the place where most of the galaxy’s matter is concentrated, once every 30m years or so. Read More

New Proposed Particle could Lead to Dark Matter Detection?

February 1, 2015 |

Dark matter has been one of the most elusive part of Universe’s mass, it may be all around us but, as yet, its existence is entirely theoretical. While dark matter is believed to account for 84.5 percent of the total matter in the universe no telescopes can detect it. So Why we can’t detect it? Read More

Researchers may have Detected First Signs of Dark Matter

December 12, 2014 | 1

Dark matter seemed to be a myth to some scientists and a catch-all to others, using it to explain gravitational forces and the orbits of objects in space that just couldn’t be accounted for by the existence of observable, physical matter. It has been theorized that dark matter existed and affected the way the universe functioned as much as physical matter, but until now, dark matter has only been a theory. Read More

Interesting Facts about Dark Matter

December 3, 2014 | 1

Dark matter is something that an astronomer or scientist cannot observe through ordinary telescopes. It does not emit or absorb light, and is considered responsible for holding all the normal matter in the universe together. Normal matter is something which can be observed and recorded through available means of technology. This article lists some very interesting facts about dark matter. Read More

Dark Future of the Universe: Dark Matter Replaced by Dark Energy

November 1, 2014 | 1

Scientists may have uncovered some startling new information about dark matter and dark energy. They’ve discovered hints that dark matter is slowly being swallowed by dark energy that grows as it interacts with dark matter. This, in turn, is slowly the growth of structure in the cosmos. Read More

Historic Breakthrough: Dark Matter may have been Detected

October 24, 2014 |

Dark matter seems to be almost a thing of science fiction rather than science. It cannot be seen, but it’s thought to make up around 85 percent of all matter in the entire universe. It’s a web that, stretching throughout space, is believed to give the actual cosmos its very structure… and yet, so far, its detection has eluded science. Read More
