The Deep Hot Biosphere : Foreword by Freeman Dyson (1998. XIV, 235 p. w. figs. 24,5 cm)

Physicist Thomas Gold here explains the idea of a deep, hot biosphere: the theory that there exists, deep within the ground, a bacterial realm containing greater mass than all surface life. This idea has important implications for the origins of life, the origins of natural gas and petroleum, and the distribution of life in the universe.
