Dark Matter

3. Hypothetical lightweight particle that is another leading candidate for dark matter
5. Invisible substance inferred from galaxy rotation and gravitational lensing that makes up about 27% of the universe
7. Particle accelerator at CERN that searches for dark matter by detecting missing energy in high-energy collisions
8. Standard cosmological model describing a universe dominated by dark energy and dark matter
11. Unaccounted-for quantity in high-energy collisions suggesting the presence of unseen particles
12. Hypothetical dark matter candidate composed of weakly interacting massive particles
14. Graph showing that stars in galaxies move faster than expected, providing evidence for dark matter
15. Satellite that mapped the cosmic microwave background and helped determine the universe is mostly dark matter and dark energy
16. Galaxy cluster collision where visible matter and gravitational mass separate, providing direct evidence for dark matter
17. Force that reveals dark matter’s presence through its effects on visible matter and light

1. U.S. underground research facility in South Dakota where the LUX-ZEPLIN dark matter experiment is operated by an international collaboration
2. Large-scale filament structure of the universe formed by dark matter and galaxies
4. Large system of stars whose outer regions rotate faster than predicted by visible mass, providing evidence for dark matter
6. Stretching of light to longer wavelengths used to measure the expansion rate of the universe
7. Underground experiment in South Dakota using liquid xenon to detect rare interactions with dark matter particles
9. Ordinary matter (about 5% of the universe) made of protons and neutrons
10. Bending of light by massive objects, showing more mass exists than we can see
13. Mysterious form of energy making up about 68% of the universe that drives its accelerated expansion
