The Largest 3D Maps of Our Universe

The last century has seen a revolution in our understanding of the cosmos, including its age—13.8 billion years—and content: 95% dark matter & dark energy; 5% normal matter! To test cosmology theories and to grasp how stars and galaxies formed, UC Berkeley collaborates world-wide to make huge 3D maps of hydrogen, the most abundant cosmic element.
