Vera Gluscevic, an astrophysicist, walks through computer simulations that model the universe's evolution from its earliest quantum-scale beginnings to the present cosmic web. The talk centers on dark matter, the unseen substance that shapes galaxy formation, and how tracing its clumping across cosmic time offers clues to its fundamental properties. Gluscevic presents this as a visual tour of simulation output rather than a derivation-heavy physics lecture, aimed at a general audience at the Institute for Advanced Study's Friends Lunch series. She also turns to a methodological question: as artificial intelligence takes on more of the analysis in cosmological research, is it extending scientists' reach or quietly replacing their role in discovery? The talk closes on that open tension between computational power and human insight in modern astrophysics.
