In 1999, Davies, in his The 5th Miracle: the Search for the Origin and Meaning of Life, reflected about his thoughts on Fred Hoyle’s 1957 science fiction novel The Black Cloud, wherein a large cloud of gas from interstellar space arrived in the solar system, which was said to be ‘alive’, as follows:
- “How can a cloud be alive? I puzzled over this at length. Surely gas clouds just obey the laws of physics? How could they exhibit autonomous behavior, have thoughts, make choices? But, then, it occurred to me, all living things supposedly obey the laws of physics.”
- — Paul Davies (1999), The 5th Miracle (pg. 14)
Hoyle’s "living cloud" theory left Davies ‘baffled and vaguely disturbed’, leaving him questioning the ‘what exactly is life question’ and ‘when did it start?’ issue.
