PBS Space Time examines the Silurian hypothesis, the idea that an industrial civilization could have existed on Earth before humans. It looks at what traces such a civilization might leave in the geological record.
HN 推薦的原因： HN uses it as an approachable treatment of whether an earlier industrial civilization would be detectable in geology.
