My English Lit. teacher (who's also head of the dept.) told me that he heard about a year ago that scientists had found that the development of stalagmites and stalactites was influenced by sounds in the cavern, that the developing layers were soft enough to be compressed by sound waves, and that this meant that they might potentially record sound - in theory allowing us to hear ancient conversations.
If this is true, it's some of the most exciting news I've ever heard. However, I can't find any references to this idea. Has anyone else heard of this and can provide me with references?
