I have asked experts at Livermore but they think asking means I'm a terrorist so they declined. I'm looking for a time line, not math formulas, and not a one sentence answer. My reason for asking is to answer questions like "Why doesn't the high explosives destroy the device before a nuclear reaction can start?"
