Riess, discoverer of dark energy: "Einstein would be amazed by the accelerated expansion of the Universe"

Adam Riess, a Nobel Prize-winning astrophysicist, discusses his groundbreaking work on dark energy and the accelerated expansion of the universe. He reflects on his initial doubts about his findings, which contradicted established theories, and how collaboration with peers led to the acceptance of the cosmological constant, a concept Einstein had previously dismissed. Riess emphasizes the importance of skepticism and curiosity in scientific research, encouraging young scientists to trust their observations. He expresses awe at the universe's mysteries, including the nature of dark energy and the origins of the universe, while remaining cautious about speculative theories like the multiverse.
