The Universe is too heavy. According to our measurements of the normal matter in the Universe, there’s not nearly enough of it to account for the strength of the gravitational effects we can see.   Whatever is making up the rest of the mass is nothing we can detect directly, and the quest to figure … Read more

Detector designed for gravitational waves seeks signal from dark matter | Science

by

In a feat of scientific repurposing, a team of physicists has used a detector designed to sense gravitational waves—fleeting ripples in space and time set off by, for example, the collisions of two black holes—to search for something even more elusive, dark matter. Although researchers found no sign of the particular hypothetical particles they sought, … Read more
