Biography
Alex Filippenko is the kind of scientist who makes the cosmos feel immediate. A professor at UC Berkeley, his career has been a relentless hunt for the supernovae—exploding stars—that serve as cosmic mile markers. His work with both the High-Z Supernova Search Team and the Supernova Cosmology Project provided critical evidence that the universe is not just expanding, but doing so at an ever-increasing rate, driven by a mysterious force dubbed dark energy. This discovery, which netted others the 2011 Nobel Prize in Physics, upended decades of cosmological thinking. Beyond research, Filippenko is a rock star of science communication, known for his wildly popular introductory astronomy courses and frequent appearances on television documentaries, where his palpable enthusiasm makes the most distant phenomena feel thrillingly close.
Baby Boomers
1946–1964
The largest generation in history at the time. Shaped by postwar prosperity, the Vietnam War, the sexual revolution, and Watergate. They questioned every institution their parents built — then ran them.
Alex was born in 1958, placing them squarely in the Baby Boomers. The events that shaped this generation — postwar prosperity, civil rights, Vietnam, and the counterculture — shaped the world they entered and the choices available to them.
