Contact

I left the office one evening a few weeks back, and while I was walking up the street, James Box cycled past, waving a hearty good evening to me. I didn’t see him at first. I was in a state of maximum distraction. For one thing, there was someone walking down the street with a magnificent Irish wolfhound. If that weren’t enough to dominate my brain, I also had headphones in my ears through which I was listening to an audio version of a TED talk by Donald Hoffman called Do we really see reality as it is?

It’s fascinating—if mind-bending—stuff. It sounds like the kind of thing that’s used to justify Deepak Chopra style adventures in la-la land, but Hoffman is deliberately taking a rigorous approach. He knows his claims are outrageous, but he welcomes all attempts to falsify his hypotheses.

I’m not noticing this just from a short TED talk. It’s been one of those strange examples of synchronicity where his work has been popping up on my radar multiple times. There’s an article in Quanta magazine that was also republished in The Atlantic. And there’s a really good interview on the You Are Not So Smart podcast that I huffduffed a while back.

But the most unexpected place that Hoffman popped up was when I was diving down a SETI (or METI) rabbit hole. There I was reading about the Cosmic Call project and Lincos when I came across this article: Why ‘Arrival’ Is Wrong About the Possibility of Talking with Space Aliens, with its subtitle “Human efforts to communicate with extraterrestrials are doomed to failure, expert says.” The expert in question pulling apart the numbers in the Drake equation turned out to be none other than Donald Hoffmann.

A few years ago, at a SETI Institute conference on interstellar communication, Hoffman appeared on the bill after a presentation by radio astronomer Frank Drake, who pioneered the search for alien civilizations in 1960. Drake showed the audience dozens of images that had been launched into space aboard NASA’s Voyager probes in the 1970s. Each picture was carefully chosen to be clearly and easily understood by other intelligent beings, he told the crowd.

After Drake spoke, Hoffman took the stage and “politely explained how every one of the images would be infinitely ambiguous to extraterrestrials,” he recalls.

I’m sure he’s quite right. But let’s face it, the Voyager golden record was never really about communicating with an alien intelligence …it was about how we present ourself.

How a Couple of Guys Built the Most Ambitious Alien Outreach Project Ever | Science | Smithsonian

One might think sending messages to other stars would be a massive, expensive job. No. It isn’t. The Cosmic Call was essentially a crowdfunded hobby project.

The Last Pictures: Contemporary pessimism and hope for the future by Paul Glister

From the cave paintings at Lascaux to the Pioneer plaques and Voyager golden records to Trevor Paglen’s “The Last Pictures” project, Paul Glister examines the passage and preservation of art and information through time. Fascinating.

Or perhaps, as Paglen envisions, those who find a Pioneer Plaque, a Voyager Record, or one of our electromagnetic transmissions will be interested enough to search us out, coming upon a future Earth where all that is left of humanity are our terrestrial ruins and that artificial ring of geosynchronous satellites, with one of them having a particular golden artifact bolted to its pitted hull. In that scenario, about all that would be left for the visiting ETI to do in terms of learning about us would be grand-scale dumpster diving.
