“Every text ever created contains complete ‘possible subtexts’. We developed an algorithm that allows us to scan these subtexts for evidence of nonhuman intelligences having woven information into the texts via human authors in this fashion.

9% of texts appear to contain evidence of this. In 3% it is irrefutable, and the information encoded comprises actual discoveries impacting mathematics, linguistics, physics, biology or other fields of formally structured inquiry. In effect, we are now able to mine our own texts for communications from ‘alien intelligences’.

The signals are not from space. They are from us.”
