Cat encounters

The latest episode of Ariel’s excellent Offworld video series (and podcast) is all about Close Encounters Of The Third Kind.

I have such fondness for this film. It’s one of those films that I love to watch on a Sunday afternoon (though that’s true of so many Spielberg films — Jaws, Raiders Of The Lost Ark, E.T.). I remember seeing it in the cinema — this would’ve been the special edition re-release — and feeling the seat under me quake with the rumbling of the musical exchange during the film’s climax.

Ariel invited Rose Eveleth and Laura Welcher on to discuss the film. They spent a lot of time discussing the depiction of first contact communication — Arrival being the other landmark film on this topic.

This is a timely discussion. There’s a new book by Daniel Oberhaus published by MIT Press called Extraterrestrial Languages:

If we send a message into space, will extraterrestrial beings receive it? Will they understand?

You can a read an article by the author on The Guardian, where he mentions some of the wilder ideas about transmitting signals to aliens:

Minsky, widely regarded as the father of AI, suggested it would be best to send a cat as our extraterrestrial delegate.

Don’t worry. Marvin Minsky wasn’t talking about sending a real live cat. Rather, we transmit instructions for building a computer and then we can transmit information as software. Software about, say, cats.

It’s not that far removed from what happened with the Voyager golden record, although that relied on analogue technology — the phonograph — and sent the message pre-compiled on hardware; a much slower transmission rate than radio.

But it’s interesting to me that Minsky specifically mentioned cats. There’s another long-term communication puzzle that has a cat connection.

The Yukka Mountain nuclear waste repository is supposed to store nuclear waste for 10,000 years. How do we warn our descendants to stay away? We can’t use language. We probably can’t even use symbols; they’re too culturally specific. A think tank called the Human Interference Task Force was convened to agree on the message to be conveyed:

This place is a message… and part of a system of messages… pay attention to it! Sending this message was important to us. We considered ourselves to be a powerful culture.

This place is not a place of honor…no highly esteemed deed is commemorated here… nothing valued is here.

What is here is dangerous and repulsive to us. This message is a warning about danger.

A series of thorn-like threatening earthworks was deemed the most feasible solution. But there was another proposal that took a two pronged approach with genetics and folklore:

  1. Breed cats that change colour in the presence of radioactive material.
  2. Teach children nursery rhymes about staying away from cats that change colour.

This is the raycat solution.
