National Geographic Live: Mapping the Expanding Universe

Landing the Mars Curiosity Rover, discovering new exoplanets, or uncovering supermassive black holes are among the most widely known and celebrated achievements in science today. But ask Dr. Adam Riess, Professor of Astronomy and Physics at Johns Hopkins University, and he might say the best is yet to come.

Riess won the 2011 Nobel Prize in Physics, along with Saul Perlmutter and Brian P. Schmidt, for his work in providing evidence that the universe is expanding at an accelerated rate. This phenomenon is widely attributed to the existence of dark matter, which could account for 84 percent of the matter in the universe. Dark matter is thought to play a role in gravitational effects on visible matter, and its detection could offer vital clues about the initial formation and eventual fate of our universe.

Check back with us later for part three of this series on Mapping the Unknown from National Geographic Live. In the meantime, watch Riess explain mapping the unknown in our cosmos and the search for dark matter.
