The universe isn’t adding up—and it’s creating a crisis in cosmology. Nobel Prize winner Adam Riess explains why measurements of the universe’s expansion rate from its earliest light and from nearby galaxies don’t match, and how this growing gap threatens the foundations of our standard model of the cosmos.

Adam Riess is an astrophysicist, professor at Johns Hopkins University, and a distinguished astronomer at Space Telescope Science Institute. In 2011, he was named as a co-winner of the Nobel Prize in Physics for his contributions to the discovery that the expansion rate of the universe is accelerating. Since then he has continued refining measurements of cosmic expansion and the Hubble constant, aiming to find and measure the most distant type Ia supernovae known, to probe the origin of cosmic acceleration.
"Particles of Thought" is hosted by Hakeem Oluseyi, an astrophysicist, author, STEM educator, multi-patented inventor, science journalist, TV personality, science communicator, and inspirational speaker. His research is based on "hacking stars" to understand our universe better and develop innovative new technologies. Oluseyi’s work has resulted in 11 patents and more than 100 publications covering contributions to astrophysics, cosmology, and plasma physics and the development of space missions, observatories, focal plane instruments, detectors, semiconductor manufacturing, and ion propulsion.
