The Simple Vacuum Energy Question Nobody Could Answer!

Why does empty space appear to gravitate so much less than quantum theory suggests? This animated physics documentary examines the vacuum catastrophe: estimates of vacuum energy that can exceed the value inferred from cosmic expansion by 120 orders of magnitude. Beginning with Wolfgang Pauli's calculation, we follow the physics of quantum fluctuations and measurements of vacuum effects before turning to Einstein's cosmological constant. We then examine the enormous mismatch, why simply subtracting the energy does not resolve it, and how supersymmetry offered a possible way forward. The final part turns to the evidence for dark energy, the coincidence problem, and proposed explanations involving the landscape and the multiverse. We consider whether dark energy could change over time, and what this unresolved conflict between quantum physics and gravity might reveal about a future theory.
