Query: Intelligent thinking outside the box by one of the old masters.

Thomas Gold began his career in the fifties. Along with Herman Bondi and Fred Hoyle he practically invented modern cosmology. They may have missed the mark with their steady-state theory, but they predicted hydrocarbons in space. In this his final work he lays out the case for a deep well of those hydrocarbons having been part of the package when Earth was formed (along with at least ten other bodies in our solar system, several of which have been confirmed by more recent observations). The Deep Hot Biosphere proposes that life on Earth may have been made possible by the slow upward seep of those buried hydrocarbons, rather than the other way around as accepted theories hold. Thomas Gold made a career of turning accepted views upside down, and he was right more often than not. He could well be right on this one too. He lays out a strong case for it.
