The Surprising Role Dolphins Have Played in the Search for ET

Dolphins, with their apparent alien intelligence, have been seen by scientists interested in ET as a stand-in

In a recent essay, Thomas Moynihan, a researcher with Oxford’s Future of Humanity Institute, puts the explosion of interest in dolphin intelligence in context: It began during the Space Race (1957–1998) — which helped fuel and fund the search for extraterrestrial intelligences. Its development also coincided withe Cold War (1946–1991) between the US and the USSR. In 1961, amid the growing tensions, neuroscientist John C. Lilly claimed that he had made contact with the first “alien” intelligence. But, as Moynihan says, Lilly “wasn’t talking about little green men from Tau Ceti, he was talking of minds much closer to home: bottlenose dolphins.” Why dolphins? As Moynihan recounts, from ancient times, mariners knew that dolphins were intelligent and modern zoologists like…

We Won’t Find ET on Ocean Planets, Researchers Say

We will see few extraterrestrials if a great many promising exoplanets are Waterworlds

Science writer Matt Williams has been writing a series on the question of why, despite the size of our galaxy, we see no other intelligent life forms. It could be, he suggests, that “many planets out there are just too watery!” Williams points out that, although water covers 71% of Earth’s surface, it is only 0.02% of the planet’s mass. If the proportion were much higher, Earth would be an ocean planet because the water would surface. It’s an open question whether an ocean planet would feature highly technologically developed intelligent life forms. Dolphins, for example, are quite intelligent but they do not seek to use any technology. The question of whether a planet could have too much water arose,…
