Potential signs of 'interacting' dark matter suggest it is not completely dark after all
Astronomers believe they might have observed the first potential signs of dark matter interacting with a force other than gravity.
Large Hadron Collider starts up again after two-year upgrade
The world's largest particle smasher restarted Sunday after a two-year upgrade that will allow physicists to explore uncharted corners of what makes up the universe, including dark matter and antimatter.
Galaxy clusters collide—dark matter still a mystery
When galaxy clusters collide, their dark matters pass through each other, with very little interaction. Deepening the mystery, a study by scientists at EPFL and the University of Edinburgh challenges the ...
Dark Energy Survey creates detailed guide to spotting dark matter
Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world's most powerful digital cameras, are the largest contiguous ...
The mysterious dark energy that speeds the universe's rate of expansion
The nature of dark energy is one of the most important unsolved problems in all of science. But what, exactly, is dark energy, and why do we even believe that it exists?
Physics community to discuss latest results of the Alpha Magnetic Spectrometer experiment
The Alpha Magnetic Spectrometer (AMS) collaboration will present today the latest results in its quest to understand the origin of cosmic rays and dark matter. These intriguing results will be shared and discussed ...
Physicists energized about restart of Large Hadron Collider
When Kevin McDermott and Susan Dittmer talk about what they might discover when their particle detector goes back online in Switzerland, it's a little like talking to a 5-year-old on Christmas Eve.
How can dark matter cause chaos on Earth every 30 million years?
In 1980, Walter Alvarez and his group at the University of California, Berkeley, discovered a thin layer of clay in the geologic record, which contained an unexpected amount of the rare element iridium. ...
Dark matter is darker than once thought
This panel of images represents a study of 72 colliding galaxy clusters conducted by a team of astronomers using NASA's Chandra X-ray Observatory and Hubble Space Telescope. The research sets new limits on ...
