Adam Riess

Adam Riess, born on December sixteenth, nineteen sixty-nine, is a prominent American astrophysicist and a Bloomberg Distinguished Professor at Johns Hopkins University and the Space Telescope Science Institute. His groundbreaking research focuses on utilizing supernovae as cosmological probes, which has significantly advanced our understanding of the universe.

Riess is perhaps best known for his pivotal role in the discovery that the expansion of the universe is accelerating. This remarkable finding earned him the prestigious Shaw Prize in Astronomy in two thousand six and the Nobel Prize in Physics in two thousand eleven, which he shared with esteemed colleagues Saul Perlmutter and Brian Schmidt.

In recent years, Riess has been at the forefront of a scientific debate surrounding the “Hubble tension.” This term refers to the ongoing discrepancy between the expansion rate of the universe measured through nearby supernovae and the measurements derived from the cosmic microwave background radiation, as predicted by the Standard Model of cosmology. His data has sparked critical questions and further investigations into whether the Standard Model remains a valid description of our universe.
