Stephen Hawking and The Theory of Everything

Two decades after A Brief History of Time dazzled readers with cosmic puzzles, Stephen Hawking admits the "theory of everything" he once thought was close—a complete explanation of existence—still slips through his fingers. His body continues to fail, yet his devotion to the work hasn't wavered, a fierce resolve glimpsed in candid interviews and quiet moments sharing microwave meals with admiring students. The first half of this two-part portrait sparkles with lively science explainers, but Hawking himself stays stubbornly elusive, as hard to pin down as the quantum riddles he's spent a lifetime chasing.
