This is amazing, though not surprising. It brings back Star Trek memories, specifically the movie where Kirk has to travel to the past bring back Humpback Whales, which man in his ignorance has hunted to extinction. They respond in “whale song” to the probe so it doesn’t destroy the earth. In the move Spaceman, the hero is a member of SETI. I never knew it really existed. Funny how fiction isn’t so fictitious. Thank you for sharing this.
