A new search for dark matter has turned up empty handed — but, in a silver lining, the effort provided important limits that will help future experiments narrow down the hunt for this elusive substance. Most astronomers believe that dark matter accounts for 85 percent of all mass in the universe, and that its existence … Read more
Astronomers estimate that roughly 85% of all the matter in the universe is dark matter, meaning only 15% of all matter is normal matter. Accounting for dark energy, the name astronomers give to the accelerated expansion of the universe, dark matter makes up roughly 27% of all the mass energy in the cosmos, according to … Read more
Gigantic deserts of almost complete nothingness that make up most of the universe may be causing the expansion of the universe to speed up, new research suggests. That means these vast tracts of nothingness could explain dark energy, the mysterious force that seems to be flinging the universe apart. Welcome to the desert Zoom all … Read more
Dark matter, the elusive substance that accounts for the majority of the mass in the universe, may be made up of massive particles called gravitons that first popped into existence in the first moment after the Big Bang. And these hypothetical particles might be cosmic refugees from extra dimensions, a new theory suggests. The researchers’ … Read more
Large galaxies may steal dark matter from smaller galaxies they nearly collide with, new research suggests. Scientists from the University of California, Irvine and Pomona College used computer models to simulate the evolution of a corner of the universe about 60 million light-years across. The new computer models, which weren’t designed to do so, created … Read more
