Dark Matter

1. Bending of light by massive objects, showing more mass exists than we can see
6. U.S. underground research facility in South Dakota where the LUX-ZEPLIN dark matter experiment is operated by an international collaboration
7. Invisible substance inferred from galaxy rotation and gravitational lensing that makes up about 27% of the universe
9. Ordinary matter (about 5% of the universe) made of protons and neutrons
11. Force that reveals dark matter’s presence through its effects on visible matter and light
12. Particle accelerator at CERN that searches for dark matter by detecting missing energy in high-energy collisions

2. Large system of stars whose outer regions rotate too fast, providing evidence for unseen mass
3. Mysterious form of energy making up about 68% of the universe that drives its accelerated expansion
4. Missing quantity in particle collisions that may indicate production of dark matter particles
5. Satellite that mapped the cosmic microwave background and helped determine the universe is mostly dark matter and dark energy
8. Standard cosmological model describing a universe dominated by dark energy and dark matter
10. Hypothetical weakly interacting massive particle that is a leading dark matter candidate
12. Underground experiment in South Dakota using liquid xenon to detect rare interactions with dark matter particles
