Dark matter is an invisible, mysterious substance that makes up more than 80% of the matter in the universe — but scientists aren't sure what it is. While it doesn't emit, absorb, or reflect light, we know dark matter exists because of the way its gravity affects visible matter. Galax...
Suppose the lightest superpartner (LSP) is observed at colliders, and WIMPs are detected in explicit experiments. We point out that one cannot immediately conclude that cold dark matter (CDM) of the universe has been observed, and we determine what measurements are necessary before such a ...
Roughly 85 percent of mass in the universe is "dark matter" -- mysterious material that can't be directly observed but has an immense influence on the cosmos. What exactly is this strange stuff, and what does it have to do with our...
Dark matter accounts for 23.3 percent of the cosmos, and dark energy fills in 72.1 percent [source: NASA]. Together, these materials make up a whopping 95.4 percent of the universe, so it's no wonder we're still trying to figure out exactly what dark energy is. Contents The Cosmic ...
Thus, dark matter's gravitational impact is extremely spread out and, it turns out, can only be observed when we look at the large-scale distribution of visible matter in the universe: things like galactic superclusters and the corresponding super-voids. It's theorized that after the Big Bang...
Dark matter makes up about 85 percent of the total matter in the universe, accounting for more than five times as much as all ordinary matter. Dark matter played an important role in the formation of galaxies. Researchers use astronomical surveys to build maps of the location of dark matter ...
Dark matter could be the result of fermions pushed into a warped fifth dimension. This theory builds on an idea first stated in 1999, but is unique in its findings. Dark matter makes up 75 percent of matter but has never been observed ... yet.Scientists say they can explain dark matte...
Closed, open or flat universe? Roughly68 percent of the universeis dark energy and 27 percent is dark matter. The remainder is normal matter, which accounts for planets, stars and other bodies. The universe’s density refers to how much of this matter is packed into a given volume of spac...

There's alsodark matter, which we can infer only from its gravitational effects, but we know it must account for about85% of all matterin the universe. Having a handle on the amount of dark matter in the universe is crucial for figuring out its geometry and its fate. ...
