Long before Earth existed, a cloud of gas and dust drifted through the galaxy in relative calm, until something disturbed it. This film traces how scientists arrived at the nebular theory, the idea that gravity slowly pulled a rotating disc of material into a sun and its orbiting planets, and then complicates that tidy picture with evidence that the process was anything but gentle. Isotopes found in ancient meteorites point to a nearby supernova whose shockwave may have triggered the collapse that formed our system in the first place, and the film walks through how researchers read that violent history out of rock chemistry rather than direct observation. Interviews and animated reconstructions cover collisions between proto-planets, the bombardment period that scarred the Moon, and the theories explaining why the inner planets are rocky while the outer ones became gas giants. The result is less an origin story than a case built piece by piece, from meteorite fragments to orbital mechanics, for a solar system that started in chaos rather than quiet accretion.
