Taking the temperature of dark matter

Warm, cold, just right? Physicists at the University of California, Davis are taking the temperature of dark matter, the mysterious substance that makes up about a quarter of our universe.

The measurements of the expansion of the universe don't add up

Physicists use two types of measurements to calculate the expansion rate of the universe, but their results do not coincide, which may make it necessary to update the cosmological model. "It's like trying to thread a cosmic ...

Cesium vapor aids in the search for dark matter

The hunt for dark matter is one of the most exciting challenges facing fundamental physics in the 21st century. Researchers have long known that it must exist, as many astrophysical observations would otherwise be impossible ...

Ultra-rare kaon decay could lead to evidence of new physics

Scientists searching for evidence of new physics in particle processes that could explain dark matter and other mysteries of the universe have moved one step closer, with the new result of the NA62 experiment reported today ...

International team of physicists continues search for new physics

Dark matter, which is thought to account for nearly a quarter of matter in the universe (but has yet to be observed), has perplexed physicists for decades. They're constantly looking for something surprising to show up in ...
