How does it challenge our current understanding of the universe? Why do different methods of measuring the universe’s expansion yield different results? And does our cosmological model need a complete overhaul? I had the honor of discussing all this and more with none other than Adam Riess. Riess is a renowned astrophysicist who won the Nobel Prize in Physics for his groundbreaking research on the expansion of the universe. Through extensive measurements and collaborations with other scientists, Riess discovered an intriguing tension in the size of the expansion of the universe, which has been steadily increasing over the last decade. These results, which have reached a significant level of more than 5 sigma, have revealed an unexpected phenomenon: the universe's expansion rate seems to vary depending on whether we start from the beginning shortly after the Big Bang or from the present. In this episode of Into the Impossible, Riess and I explore the challenges of measuring distances in the universe, the possible role of dark energy, and how this challenges the concept of the cosmological principle.
