After 40 years spent dissecting meteorites in search of the origins of the solar system, John Wood believes that his field is swamped by details and faces a dead end--but he offers a way out. Wood exhorts his meteoritic colleagues to adopt a top-down, inductive approach, starting with astrophysics. What's needed are astrophysical models that could be tested with the geochemical data, he says, much the way bricks might be fit into the steel framework of a modern building. But not everyone is optimistic about Wood's astrophysical approach.
