What happens when your data rewrites the laws of physics? Adam Riess takes us inside the discovery of dark energy.
What does it feel like to make one of the biggest discoveries in physics? Adam Riess knows — because his work revealed that the universe isn’t just expanding, it’s accelerating. In this episode, the Nobel Prize–winning astrophysicist takes us behind the scenes of the moment that changed cosmology forever. How did his team use exploding stars as “standard candles” to measure the cosmos? Why did the data point to a mysterious force now called dark energy, making up nearly 70% of the universe? And what’s behind today’s biggest cosmic puzzle: the Hubble tension? Plus, Adam shares what new telescopes could uncover — and why the next decade might rewrite the laws of physics all over again.
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.
