dark matter

Scientists furthered studies of the Higgs boson, neutrinos, dark matter, dark energy and cosmic inflation and continued the search for undiscovered particles, forces and principles.

LUX-ZEPLIN (LZ), a next-generation dark matter detector that will be at least 100 times more sensitive than its predecessor, has cleared another approval milestone and is on schedule to begin its deep-underground hunt for theoretical particles, known as weakly interacting massive particles, in 2020.

How do scientists know what percentages of the universe are made up of dark matter and dark energy? Cosmologist Risa Wechsler of the Kavli Institute for Particle Astrophysics and Cosmology explains. Watch the 3-minute video.
