        While states were counting and recounting votes to keep proving that Joe Biden convincingly won the 2020 presidential election, there were three significant scientific events the past week. This is a brief look at all three. It is offered as a kind of public service, since, if there’s one thing the last four years have demonstrated, it’s that many Americans have a tenuous, at best, relationship with science.

  1. Atlas shrugged. Dr. Scott Atlas, the quack White House coronavirus adviser, told Fox News viewers to ignore the advice of public health experts who warned Americans to avoid indoor family gatherings this Thanksgiving because the virus was spiking again in America. Atlas is a professor of neuroradiology with no background in public health. Not only did he tell American families to gather together for the holidays, he said it was for the good of their elderly relatives, those most susceptible to being seriously impacted by the virus. He said: “This kind of isolation advice is one of the unspoken tragedies of the elderly who are now being told don’t see your family at Thanksgiving. For many people, this is their final Thanksgiving, believe it or not. What are we doing here?” In other words, hey, they’re probably gonna die soon anyway, let them eat turkey on the way out. Never mind that gramps might be planning on a few more Thanksgivings. Callous doesn’t even cover this attitude. Atlas also says masks don’t protect against the virus and is a fan of so-called “herd immunity” — let the youngest and strongest prevail. The doc’s Stanford colleagues disagreed with his prescription, as did many members of the White House task force and pretty much every public health expert, all of whom were shocked at his casual disregard for older Americans. Of course, this anti-science attitude is what got him named to the Trump task force in the first place. Only the best.
  2. The CDC spoke up. Basically, it said do the opposite of what Atlas said. This is significant because, for much of the pandemic, the Centers for Disease Control, which should have been leading the effort to control the spread of the virus, has been muzzled by the Trump Administration. Here’s what the agency said: “As cases continue to increase rapidly across the United States, the safest way to celebrate Thanksgiving is to celebrate at home with the people you live with. Gatherings with family and friends who do not live with you can increase the chances of getting or spreading COVID-19 or the flu. Travel may increase your chance of getting and spreading COVID-19. Postponing travel and staying home is the best way to protect yourself and others this year.” This is not necessarily what you want to hear, but it’s short and to-the-point science with Covid-related deaths approaching 250,000 in this country. 
  3. Arecibo went silent. Oh no, what will Jodie Foster do? The famed radio observatory in Puerto Rico, which was featured in the movie, Contact, has suffered damage to two major cables that suspend the platform over the dish. Engineers for the National Science Foundation say it is not reparable because of the danger to the people who work there. Scientist said they should be able to preserve the visitors center and a couple of other scientific programs at the site, but the telescope, which has produced many scientific discoveries over nearly six decades, will be decommissioned. This is a major loss not only to NASA, but to the promotion and appreciation of science in general. That’s because Arecibo, which was vital to research in radio astronomy, atmospheric science, and radar astronomy, also was involved in the search for extraterrestrial intelligence (SETI) programs. This is one area of science in which Americans actually demonstrates an interest, even if it is often based on science fiction. Its role in the search for ET gained Arecibo prominence and popularity with the general public through movies and TV shows. The observatory was featured in the James Bond thriller, GoldenEye, the sci-fi horror flick, Species, and the afore-mentioned Contact. The popular film was based on Carl Sagan’s wonderful novel of the same name. The observatory was also featured on TV in the X-Files episode “Little Green Men.” In the movie, Contact, Foster’s character, Ellie Arroway, gives up a teaching position at Harvard University to take a seat at Arecibo’s radio telescope. Why? From the movie: Her supervisor says, “Dr. Arroway will be spending her precious telescope time listening for … uh … listening for …”  Ellie Arroway replies: “Little green men.” Precisely. We get it. They’re out there. Basically, Arecibo is a movie star and we miss movie stars when they leave us. The difference here is that this star shone even brighter in real life. Maybe we can scrap Trump’s Space Farce for a new set of space ears.

The Arecibo Message ... sent in 1974

The Arecibo Message … sent in 1974

I pause in my search for intelligent life in the White House to ruminate on another project which may well promise quicker results — the search for intelligent life elsewhere in the universe.

The search is known as METI: Messaging to Extraterrestrial Intelligence. This is not to be confused with SETI (Search for Extraterrestrial Intelligence), which deals with searching for messages from aliens. To/from. Therein lies the difference as well as a major scientific/philosophical dispute.

The SETI project was popularized in the novel, “Contact,” by astronomer, cosmologist, astrophysicist Carl Sagan, who was central, along with astronomer, astrophysicist Frank Drake, in creating the program by which huge radio telescopes have listened for decades — still do — for signals from far-distant civilizations.

The book was later made into a movie starring Jodie Foster. You may remember it. It vaguely resembles the book, which I only recently finished reading as part of my return-to-reading movement that was sparked by a “sudden” appreciation of the science of synchronicity. In brief, I started noticing that coincidences led to more coincidences — books led to other books, ideas to other ideas, etc. — and that I ignored the connection between events/people/things at my own loss.

There was a reason that article by Steven Johnson about METI appeared on the cover of The New York Times Magazine two weeks ago. It was to catch me up on where the search for evidence of life elsewhere in the universe had gone since Sagan’s book was published in 1985. What purpose it may have served for you, I haven’t a clue, but for me it meant there was probably some issue to write about that could lead to more fruitful thought than that monotonous White House disaster.

The fact that I live in Pine Bush, a hamlet in upstate New York known as the UFO capital of the Northeast, just clinched the deal. Of course, in Pine Bush there are quite a few people who believe that extraterrestrials have already been here more than once. Checking us out. Maybe so, but since I have yet to experience a UFO, I’m interested in the debate going on over SETI vs. METI.

It boils down to: It’s all well and good to listen for messages from outer space. If we receive one, it means there is other life out there. We can then decide how, or whether, to respond. The hesitation has to do with not knowing if the other life is friendly or not. If we send out a big hello to the universe, the nay-sayers argue, any civilization that receives it will be far more advanced than ours and could well look upon us as Columbus did on the Native Americans. As Stephen Hawking, the most prominent METI nay-sayer, pointed out, that experience “did not go well” for the Native Americans. Do not advertise our presence, he says, and Elon Musk and many other scientists agree.

But many others disagree, arguing that another civilization, advanced enough to receive our message, would likely also be advanced enough to  understand the value of being peaceful.

So, what to do?

METI’s web page lists several objectives, including:

  • “Promote international cooperation and collaboration in METI, SETI, and astrobiology.
  • “Understand and communicate the societal implications and relevance of searching for life beyond Earth, even before detection of extraterrestrial life.
  • “Research and communicate to the public the many factors that influence the origins, evolution, distribution, and future of life in the universe …”

I’d say the non-profit agency has noble, worthwhile goals. It’s the kind of project that could serve to remind all of us Earthlings of our relative insignificance in the universe and serve as a unifying, educational mission for our querulous planet. Of course, with even scientists being in disagreement about whether to send or just keep listening, I’m skeptical about political leaders being able to reach agreement. In fact, there’s an argument just waiting for the anti-science crowd to adopt: The Fermi Paradox.

Enrico Fermi, an Italian physicist who created the first nuclear reactor, asked (I paraphrase): If the universe is so big (100 billion galaxies, 50 sextillion Earth-like planets) and so old (13.82 billion years), there should be 10,000,000,000,000,000 intelligent civilizations in the observable universe and, after millions of years of technological progress, an alien civilization should be capable of long-distance space travel. So where is everyone?

Well, as I said, there are some neighbors of mine who say aliens have already been here. How could we miss them? Government coverup of UFO sightings is a popular — and not wholly dismissible — theory.

Either way, I say the METI people — who used to be the SETI people — have the right idea. Be pro-active. Send out a big hello to the universe. An inter-galactic tweet. Get an international group of smart, sensitive people from various walks of life to create it. Set up contingencies for what to do if we get a reply … or a visit. War or peace. Then push the button over and over again for however long it takes for some life form out there to receive and understand it.

For the record, a three-minute message was sent out to the universe from the Arecibo Observatory in Puerto Rico in 1974, under the direction of Drake. It has yet to reach its destination, but it drew immediate strong opposition from the Royal Astronomer of England at the time, who, like Hawking, warned of placing the earth in peril. Since then, we’ve been mostly listening.

I don’t expect to be around when the message is received — they’re talking about light years here, remember — but I do think it’s the synchronistic thing to do. Someone has to get the ball rolling. Douglas Vakoch, the head of METI, says the fears are exaggerated. He thinks 100 years of television and radio signals sent into space should have — for better or worse — already alerted aliens to our existence and he plans to start sending messages next year.

So … hello, world.
