Regular readers of Skeptophilia -- and, heaven knows, my friends and family -- are well aware that one of my obsessions is the possibility of extraterrestrial life, and perhaps even extraterrestrial intelligence.
I grew up watching Lost in Space and The Invaders and the original Star Trek, and later The X Files and Star Trek: The Next Generation and Doctor Who. But while those classic shows piqued my budding interest in exobiology, my training in actual biology taught me that whatever the aliens look like, they will almost certainly not be humans with odd facial protuberances and strange accents. How evolution plays out on other planets is impossible to say, but it's likely to be vastly different from the pathways taken by life on Earth. I still remember reading Stephen Jay Gould's essay "Replaying the Tape" from his excellent book on the Cambrian-age Burgess Shale fauna, Wonderful Life, and being blown away by the following passage:
You press the rewind button and, making sure you thoroughly erase everything that actually happened, go back to any time and place in the past -– say, to the seas of the Burgess Shale. Then let the tape run again and see if the repetition looks at all like the original. If each replay strongly resembles life’s actual pathway, then we must conclude that what really happened pretty much had to occur. But suppose that the experimental versions all yield sensible results strikingly different from the actual history of life? What could we then say about the predictability of self-conscious intelligence? or of mammals?
His point was that a great deal of evolution is contingent -- dependent on events and occurrences that would be unlikely to repeat in exactly the same way. And while there's no way to re-run the tape on the Earth, this has profound implications regarding what we're likely to find elsewhere in the universe.
If we do find intelligent aliens, chances are they won't be Klingons or Romulans or Andorians. To be fair, the aforementioned shows did make some attempts to represent what truly different life might be like; the Horta from the original Star Trek and the Vashta Nerada and the Midnight Entity from Doctor Who come to mind. Most likely, though, whatever we find out there will be -- to pilfer a phrase from J. B. S. Haldane -- "queerer than we can imagine."
All of this is just a preface to my telling you about an article I read today, that should have had me excited, but ended up leaving me looking like this:
The link I'm referring to was sent to me by a loyal reader of Skeptophilia, and I've now seen the story in a number of different news sources. This particular iteration has the title, "Huge Alien Announcement 'Could Happen Within Weeks' as Professor Says 'We've Found It'." "It," in this case, is apparently definitive proof of extraterrestrial intelligence. The guy claiming this is one Simon Holland; two different scientific teams, he says, are "in a race to publish the first confirmed evidence."
And not just evidence, but actual transmissions of some kind, bringing to mind the movie Contact and the breathtaking moment astronomer Ellie Arroway finds a radio signal from another planet. Like the one in Contact, the signal Holland tells us about is some kind of narrow-band radio message, and was apparently discovered by Yuri Milner's Breakthrough Listen program."It’s a single point source, not just noise," he said. "The signal, instead of being the giant buzz of everything in the universe that we hear through all radio telescopes, was a narrow electromagnetic spectrum."
Which sounds awesome, right?
But.
First, Simon Holland isn't a professor, he's a YouTuber and filmmaker. He says he "taught at a major UK university" -- no name given -- and his nickname is "Prof." And here are a few of his recent YouTube videos:
- "Cattle Mutilation -- a Horrible 'Big Picture'"
- "Nuclear Explosions Over the Atlantic"
- "The Science Film YOU ARE NOT ALLOWED TO SEE"
- "Antigravity Machine Finished"
- "Faster Than Light: CIA and the UFO"
Not exactly a testimony to scientific rigor, right there. So how would this guy know about some find at Breakthrough Listen, especially one that is being kept hush-hush so the scientific teams themselves don't get scooped?
The other thing, though, is that we've been down this road before. Last year, we had all the hoopla over military whistleblower David Grusch, alleging that the United States had hard evidence not only of alien technology but of "biological material not of earthly origin" -- there were even extensive hearings in Congress over the matter. And the whole thing came to nothing. The upshot was, "Okay, yeah, if there are actual UFOs from another world zipping around on Earth, it would be a matter of national security," but when asked to present the actual evidence itself, all we got was a shoulder shrug.
So forgive me for being dubious about Simon Holland's claims. I'll say what I've said before; if there is proof of alien intelligence, stop acting coy and show us the goods. Until then, I'm perhaps to be forgiven for being dubious.
I'll end, however, by saying that this is one case where I devoutly hope I'm wrong. If in "a few weeks" we have publication of a paper in a peer-reviewed science journal about a radio transmission from an intelligent civilization on another planet, I will be beyond thrilled to eat my words.
But I'm not holding my breath.
