More than 50 years since astronomers first proposed "dark matter," we have no idea what it is and nobody has directly seen it or produced it in the lab.
Roughly 80 percent of the mass of the universe appears to be dark matter: an invisible material that seems to interact with ordinary matter only through gravity, without emitting light or energy. Scientists cannot detect dark matter directly and don't yet know what it's made of, but they track its influence based on the motions of stars and galaxies. The presence of dark matter is necessary to explain the universe's current structure.
Did the graviton, the quantum mechanical force carrier of gravity, flood the cosmos with dark matter before normal matter even had a chance to get started?
Though scientists know there's a supermassive black hole at the center of most galaxies, they can't explain how the gravitational giants formed.
Scientists investigating the true identity of dark matter are finding new evidence to support one leading candidate: axions.
CERN will not enter new cooperations with Russian scientific institutions following a request of Ukraine's scientists to halt partnerships with Russian science institutions.
Scientists are gearing up to once more push the boundaries of the cutting edge of particle physics with the reopening of the Large Hadron Collider (LHC) at CERN after a three-year shutdown.
Large galaxies may steal dark matter from smaller galaxies they nearly collide with, new research suggests.
Reference Roughly 80% of the mass of the universe is made up of dark matter, a material that scientists cannot directly observe. So why do scientists think it dominates?
Stellar groupings orbiting the outskirts of the Milky Way shed new light on the elusive dark matter surrounding our galaxy.
The recently launched James Webb Telescope should help determine if dark matter is made up of primordial black holes.
Astronomers wonder what holds together a distant galaxy that appears to contain no trace of dark matter.
For the first time ever, researchers have detected neutrino candidates produced by the Large Hadron Collider (LHC) at the CERN facility near Geneva, Switzerland.
Astronomers have solved a mystery that the Hubble Space Telescope first discovered nearly a decade ago. A pair of streaky objects actually appear that way thanks to a "ripple" in the fabric of space.
A new theory suggests dark matter may have come from quantum bags that got squished together in the early universe.
By entangling the motion and quantum properties of a beryllium crystal, scientists have achieved unprecedented precision for measuring electromagnetic waves.
You may have heard about the "cosmology crisis:" Different methods of measuring the age of the universe are giving different results, and cosmologists have no idea why.
Why is the universe the way it is? Over the years, scientists have explored many ways to explain the cosmos, leading to some crazy-sounding ideas.
Dark matter could be even weirder than anyone thought, say cosmologists who are suggesting this mysterious substance could interact with itself in a higher dimensional universe.
