Alien life is no joke

Acepting alien life as real took a long time but it has now appeared to have happened.  so far so good.

However, let me ruin your day.  First off all obeservations of planetary surfaces are decidely unpromising.  At best, on all of them, we have to arrive and then burrow underground to provide our own little refugia.  so far we have zero evidence of a life friendly planet anywhere we look.

Secondly we have plenty of evidence that the whole Earth moon system is carefully engineered to support a living biome.  None of this happened by accident.  does this mean that surface based life demands an accident?

way more interesting is that my Cloud Cosmology; and additional conforming evidence supports the startling idea that all planets are actually hollow constructs with a central matter production star at its center.  This creates ideal conditions inside for the emergence of a biome on the inner surface of the planet.and it is likely that our own biome was ultimately released from this egg like structure onto our outer surface.

if this actually happens to be the way of the universe, then it follows that every planet has an inner surface teeming with life and our engineered world is the wierd exception.  again we have ample conforming evidence.  Even Genesis makes actual sense folks. None of this was ever expected when we understood the Space Time Pendulum.

If we are right, then all our planets have aliens aboard and perhaps even humans, just as reported by Swedenborg and including jupiter..

Alien life is no joke

Not long ago the search for extraterrestrials was considered laughable nonsense. Today, it’s serious and scientific

Suddenly, everyone is talking about aliens. After decades on the cultural margins, the question of life in the Universe beyond Earth is having its day in the sun. The next big multibillion-dollar space telescope (the successor to the James Webb) will be tuned to search for signatures of alien life on alien planets and NASA has a robust, well-funded programme in astrobiology. Meanwhile, from breathless newspaper articles about unexplained navy pilot sightings to United States congressional testimony with wild claims of government programmes hiding crashed saucers, UFOs and UAPs (unidentified anomalous phenomena) seem to be making their own journey from the fringes.

What are we to make of these twin movements, the scientific search for life on one hand, and the endlessly murky waters of UFO/UAP claims on the other? Looking at history shows that these two very different approaches to the question of extraterrestrial life are, in fact, linked, but not in a good way. For decades, scientists wanting to think seriously about life in the Universe faced what’s been called the ‘giggle factor’, which was directly related to UFOs and their culture. More than once, the giggle factor came close to killing off the field known as SETI (the search for extraterrestrial intelligence). Now, with new discoveries and new technologies making astrobiology a mainstream frontier of astrophysics, understanding this history has become important for anyone trying to understand what comes next. But for me, as a researcher in the field of technosignatures (signs of advanced alien tech) – the new face of SETI – getting past the giggle factor poses an existential challenge.

I am the principal investigator of NASA’s first ever grant to study signatures of intelligent life from distant exoplanets. My colleagues and I are tasked with developing a library of technosignatures or evidence of technology-wielding life forms on distant planets. Taking on that role has been the culmination of a lifetime fascination with the question of life and the Universe, a fascination that formed when I was a kid in the 1970s, drinking deep from the well of science fiction novels, UFO documentaries and Star Trek reruns. Early on, as a teenager reading both Carl Sagan and Erich von Däniken (the author of Chariots of the Gods), I had to figure out how to separate the wheat from the chaff. This served as a kind of training ground for dealing with questions facing me and my colleagues about proper standards of evidence in astrobiology. It’s also why, as a public-facing scientist, I must work to understand how people not trained in science come to questions surrounding UFOs as aliens. That is what drove me, writing a recent popular-level account of astrobiology’s frontiers called The Little Book of Aliens (2023), to stare hard into the entangled history of UFOs, the scientific search for life beyond Earth, and the all-important question of standards of evidence.

The question of what constitutes evidence for an extraordinary claim made its appearance in the very first major UFO story. It was 24 June 1947, a good day for flying in the Pacific Northwest. The skies were clear and bright over Mineral, Washington. It was the middle of the day as the amateur pilot Kenneth Arnold found himself navigating his small single-engine plane past the towering peak of Mount Rainier toward an air show in Oregon. But he’d heard that a US Marine Corps transport plane had gone missing, and a reward was being offered for anyone who found its wreckage. Arnold decided to make a few circuits and have a look. He didn’t know it at the time, but he was flying straight into UFO history.

As Arnold surveyed the terrain below him, he saw a flash of light with a blue tinge. A DC-4 was flying off in the distance, but there were no flashing lights coming from it. Then the flashes appeared again. This time he saw exactly where they were coming from: nine objects flying in a diagonal formation, ‘like the tail of a Chinese kite’. Arnold watched as the objects banked and turned in ways that made him think he was watching some kind of advanced military aircraft, until they finally disappeared. The entire incident didn’t last long, but it left Arnold with ‘an eerie feeling’. After landing to refuel, he shared his story with friends at the airfield. What happened next would echo down history, shaping everything we think about UFOs and their connection to aliens from outer space.

Arnold’s tale spread quickly, and reporters from the East Oregonian asked him to come in and give more details. To the newspapermen, Arnold seemed like a credible witness and a careful observer. Laying out the timeline of what he saw, Arnold described both the craft and their motions. Exactly what happened next remains controversial, but when Arnold described the objects as moving like ‘a saucer if you skip it across the water’ he triggered a chain of events leading to one of the most outrageous misquotes in the history of journalism.

The story in the East Oregonian, a small paper, ran with the words ‘saucer-like aircraft’. But, when the Associated Press picked up the story, the description got even more garbled. What Arnold said he’d seen were flying craft shaped like a crescent with ‘wings’ that swept back in an arc. Somehow the AP wire story misinterpreted Arnold’s description, leading The Chicago Sun to run a story with a spectacular frontpage headline: ‘Supersonic Flying Saucers Sighted By Idaho Pilot.’

The Chicago Sun piece triggered an avalanche. Within six months, the flying saucer story ran in more than 140 newspapers across the US. Even more remarkable, an epidemic of flying-saucer sightings began to sweep the nation. By the end of summer in 1947, ‘flying saucers’ were officially a thing.

What’s important about the Roswell story is how loose even the idea of evidence becomes

One of the most important lessons I learned from the Arnold affair is the power of a story. Arnold saw the first flying saucer, and his sighting begins a critical thread in the public’s willingness to go along on evidence-free rides of thinking about aliens and UFOs. It was where the idea of technologically advanced, interstellar life here on Earth right now enters the public consciousness as a major phenomenon. But almost as quickly as UFOs appear, so does a UFO culture that tilts towards the incredulous and the paranoid, marked by a willingness to take anything as evidence. Of course, one could find many individuals taking an interest in UFOs while keeping their sceptical sensibilities, who just genuinely wanted to know what was going on. But, as a cultural phenomenon, public discussion of UFOs would come to be dominated by questionable evidence, conspiracy theories and outright hoaxes.

The Roswell affair embodies the most questionable evidence axis of UFO culture. The actual Roswell case involves a rancher who, just a few weeks after the Arnold sighting and its media craze, found some debris on his land made of sticks, wire and foil. While a short, initial hubbub ensued when a story in the local paper claimed the discovery of a flying saucer (what else), that claim was walked back the next day.

The brief affair was then forgotten for 30 years. It was only after that prolonged period that the Roswell story was resurrected in a series of bestselling books and TV ‘documentaries’ claiming a crashed saucer had been found on the ranch. But with each new book, the Roswell story became more complex and convoluted. Each new book added more so-called witnesses and more details, including the account of the mortician Glenn Dennis getting a chance to view the dead aliens. Some books said there were more saucers and more aliens, some dead and some not. Some even said alien bodies were viewed by none other than president Dwight Eisenhower.

What’s important about the Roswell story is how loose even the idea of evidence becomes. Anyone with a vague connection to the events and a story to tell gets added to the list of witnesses. New books pile on old books and theories multiply until even those claiming to be serious UFO researchers can’t sort out which version with how many saucers and bodies is the one they’re supposed to investigate; garden-variety enthusiasts are beyond confused.

While this might have seemed amusing to those on the sidelines at the time, it established a pattern of ‘anything goes’ in the public’s perception of UFOs and, by association, the question of alien life that continues to this day.

That loose relationship between extraordinary claims and the evidence for such claims also had a profound effect on me as a teenager interested in astronomy and the possibilities of extraterrestrial life.

At the time, I was reading both hard-science books (Sagan) and speculative works about UFO-related topics. For a time, I’d become enamoured of von Däniken’s book Chariots of the Gods (1968) and its claims that many archaeological mysteries could best be explained by ancient aliens who had once come to visit Earth. That time ended when, one evening, I chanced upon a PBS documentary called The Case of the Ancient Astronauts (1977). It presented interviews with scientists who had actually spent their lives studying the subjects of von Däniken’s ancient alien speculations. The simplicity with which hard-won archaeological evidence trumped von Däniken’s claims left me both angry (I felt duped by his book) and exhilarated. The establishment of proper standards for what counts as evidence is what set the archaeologists apart from von Däniken’s wishful fantasies. The experience of that stark difference ended my own interest in UFOs and visiting aliens of any historical epoch.

If it hadn’t made me so angry, it might have made me laugh – and it’s that giggle factor that has been so harmful to the establishment of the true scientific study of astrobiology that I work in now. When it comes to SETI, at least, UFOs made the nascent field an easy target for scorn. The first true SETI project occurred in 1960, when a young astronomer named Frank Drake used a radio telescope to search for ‘non-natural’ signals from two Sun-like stars. While Drake was looking for an intelligent life that could build technologies like radio transmitters, his project, in attempting to establish evidence for life beyond Earth, was the first true astrobiological experiment ever attempted.

Recognising Drake’s effort as the starting point for modern astrobiology is a rarely discussed but critical point. It’s also essential to understanding the remarkable moment the field stands in now because Drake’s search took that critical idea of standards of evidence seriously. In the design and application of his experiment, Drake and his colleagues paid close attention to questions of signals, noise and, most of all, false positives. They understood that they could be fooled into thinking they’d made a discovery by the data they gathered, and they attempted to prepare and protect themselves from that possibility. Drake’s SETI project and those that followed always attracted enormous popular attention. But building the field into a coherent, sustained scientific enterprise proved difficult, and it is here that UFOs got in the way.

In SETI’s heady first decades, a number of government science agencies had a healthy interest in the search for life, intelligent or otherwise. It was the US National Academy of Sciences that hosted an Interstellar Communications meeting where the Drake equation was born. And NASA was keen to go microbe hunting on the other planets in our solar system if they could be reached. As the 1960s turned into the ’70s, SETI scientists also worked with NASA in ways that went beyond radio astronomy, helping plan new telescope technologies for hunting exoplanets. There was even consideration of Project Cyclops, a massive array of a thousand radio telescopes sensitive enough to find unprecedentedly faint signals of intelligent life among the stars.

In all these projects, the scientists involved had to face the challenging task of understanding how to gather and evaluate evidence while simultaneously facing profound uncertainties concerning the target of that evidence. Researchers were well aware that, while we must begin with life as we know it (that is, Earth life), nature might have other ideas. Life, intelligent or otherwise, originating on a different world could follow entirely different trajectories. Though the field was nascent, astrobiology researchers made slow but steady progress in mapping out how to rigorously gather and evaluate data that would be relevant to the very open question of how life beyond our world might make its appearance.

The public political flogging of SETI as wasteful kookiness, with an implicit link to UFO kookiness, had begun

Then the politics and the UFOs showed up.

William Proxmire was a senator from Wisconsin who liked to think of himself as a fiscal hawk. He took it upon himself to bestow his Golden Fleece Award on anything he considered a waste of US tax dollars. Since the science projects he targeted got only meagre amounts of funding, Proxmire’s award was basically clever politics aimed at targets who couldn’t fight back. In 1978, NASA’s small portfolio of SETI funding fell into Proxmire’s crosshairs. He gave SETI the Golden Fleece Award and, being a powerful and influential senator, got his colleagues to keep the agency from providing any new funding. Proxmire only relented after Sagan, by then a well-respected public scientist, publicly intervened, meeting personally with the senator to discuss the issue. While the ban on SETI funding was eventually lifted in 1983, the public political flogging of SETI as wasteful kookiness, with an implicit link to UFO kookiness, had begun.

NASA’s SETI funding remained minuscule in the post-Proxmire period, but it was still a target. In 1990, NASA tried to ramp up its SETI funding, from $4 million to $12 million, for a new search in the microwave region of the electromagnetic spectrum. While this is less than chump change in the federal budget, some politicians once again smelled blood. Making the link to UFOs explicit, the congressman Silvio Conte of Massachusetts tried to kill the funding, claiming ‘we don’t need to spend $6 million this year to find evidence of these rascally creatures. We only need 75 cents to buy a tabloid at the local supermarket.’

The same game played out again a few years later. In 1993, those $12 million were finally allocated for the new search. Not wanting to attract more congressional attention, the project was stealthily called the High Resolution Microwave Survey. Unfortunately, the senator Richard Bryan from Nevada caught wind of the effort and saw it as an easy chance to make some headlines. He sponsored an amendment killing the project, announcing that would be ‘the end of Martian hunting season at the taxpayer’s expense’. Of course, Bryan knew NASA wasn’t planning on turning their telescopes towards Mars, but who cared? His quip made for great copy and linked SETI to the cultural fringes where UFO enthusiasm lived. What became known as the ‘giggle factor’ had killed the search for life in the Universe again.

In the wake of these very public whippings, NASA learned the lesson that SETI was political poison. While SETI scientists such as Drake and the unstoppable Jill Tarter did their best to show that the field lived within those necessary scientific standards of evidence, the damage was done. While the agency did what it could in the decades that followed, it became an accepted truth among researchers that federal support was going to be hard to come by. SETI scientists soldiered on, raising private money where they could. But, for all intents and purposes, it was running on fumes. The giggle factor had won.

Choking off SETI funding had important consequences for the search for life in the Universe because, basically, it meant there was no search for life in the Universe. Using big telescopes costs big money. If there was no funding for SETI, then no telescope time would be granted for SETI. The political temperament that held sway for so long means our sky has effectively remained unexplored. We simply have not looked.

It’s impossible to deny the role UFOs had in the development of this history. As the historian Stephen Garber put it in an article about SETI and NASA, the field ‘had always suffered from a “giggle factor” that derived from its association in the popular press with searchers for “little green men” and unidentified flying objects’. Because of this association, astronomers never got the chance to get a real search started.

In the early 1990s, it did seem that no one was very interested in the scientific possibilities for life beyond Earth. NASA’s 1976 Viking landers conducted biology experiments on Mars that appeared to close the door on the Red Planet as a home for even microbial life. The trail for life of any kind seemed to have gone cold.

Then, in the mid-1990s, everything changed.

In 1995, scientists announced that they had discovered the first planet orbiting another star – an exoplanet. It was an epoch-making moment. After 2,500 years of arguing about the existence of other worlds, we’d finally proven that the planets in our solar system were not a rarity. Soon, exoplanets were being discovered across the sky. Now we know that pretty much every star you see at night hosts a family of worlds. The next big change came when scientists found a chunk of Mars in Antarctica. The meteorite blown off the red planet (from an ancient asteroid impact) appeared to have signs of fossil life. While that conclusion is no longer accepted, at the time it drove president Bill Clinton to direct NASA to go back to Mars and look for life. Between the discovery of exoplanets and the possibilities of ancient life on Mars, NASA got into astrobiology in a big way. Funding for new research opened up, allowing new and exciting ideas to be proposed and pursued.

Remarkably, when it comes to exoplanets, we are now also able to see exactly which planets are in their star’s habitable zone, where liquid water (the key, we believe, for life) can exist. That means we know exactly where to look in our search for life (something Drake could only dream of).

Even more remarkably, astronomers have learned how to look for alien life on alien worlds using starlight that’s traversed the world’s atmosphere and is then absorbed by a variety of chemicals on the surface. This means we can search for biosignatures – signatures of chemicals that could be in a planets’ atmosphere only because life has put it there.

An open investigation of UAPs could offer a masterclass in how science goes about its business of knowing

Spectacular advances in the hunt for biosignatures have meant a profound refinement in the all-important standards of evidence. The earliest version of a biosignature was the presence of oxygen in an alien atmosphere. On Earth, oxygen is a significant atmospheric constituent only because photosynthetic organisms keep it there. Over the past decade, however, astronomers have discovered key mechanisms through which planets without life might generate oxygen-rich air. This was a crucial step in developing methods for evaluating false positives – the ways we think we’ve gained evidence for life but are, in fact, being fooled. Sophisticated statistical methods for evaluating false positives, as well as other challenges astrobiological evidence will present, are now a robust part of biosignature science.

All these new discoveries and new methods are transforming what we think of as SETI too. A new research field is rising that scientists are calling technosignatures, which embraces the ‘classic’ efforts of SETI while taking the search for intelligent life into new forms and new directions. (Some scientists still use SETI to refer to the field and that’s OK. But for many, including myself, ‘technosignatures’ correctly captures all that is changing in the field.) Rather than planning for someone to set up a beacon announcing their presence (one premise of the first generation of SETI), we can now look directly at the planets where those civilisations might be just going about their business of ‘civilisation-ing’. By searching for signatures of an alien society’s day-to-day activities (a technosignature), we’re building entirely new toolkits to find intelligent, civilisation-building life.

It was in 2019 that NASA awarded me and my colleagues the first grant to study atmospheric technosignatures. While there are still only a handful of technosignature grants compared with biosignature studies, it was the first indication that the giggle factor was finally waning. Since then, our group has worked hard to provide new examples of possible technosignatures including some that might be searched for with the James Webb Space Telescope. We’ve also demonstrated that there is no reason to suppose that biosignatures will be more common than technosignatures. Since the exact same techniques are required to search for both bio- and technosignatures, there’s every reason to carry out both kinds of search at the same time.

And those standards of evidence developed for biosignature searches will be just as relevant for technosignature work. Our group, led by the astrophysicist Manasvi Lingam from the Florida Institute of Technology, recently published the first work attempting to lay out a framework for evaluating false positives in technosignatures. While there is enormous work ahead of us, it’s projects like these that will allow us to fully understand the confidence we can ascribe to any claim of an intelligent-life detection.

With the giggle factor receding for the scientific search for life, where does that leave UFOs and UAPs? There, the waters remain muddied. It is a good thing that pilots feel they can report sightings without fear of reprisal as a matter of air safety and national defence. And an open, transparent and agnostic investigation of UAPs could offer a masterclass in how science goes about its business of knowing rather than just believing. In The Little Book of Aliens, I even explained how such an investigation might be conducted (the recent NASA UAP panel and the Galileo Project are exploring these kinds of options). But if my colleagues and I claimed we’d found life on another world, we’d be required to provide evidence that meets the highest scientific standards. While we should let future studies lead us where they may, there is simply no such evidence surrounding UFOs and UAPs that meets these standards today. In fact, at a recent hearing conducted by NASA’s UAP panel, it was revealed that government studies show only a small percentage of reported sightings failed to find a reasonable explanation. Many of the remaining cases did not have enough data to even begin an attempt at identification. The sky is simply not awash in unexplained phenomena.

In the end, what matters is that, after thousands of years of arguing over opinions about life in the Universe, our collective scientific efforts have taken us to the point where we can finally begin a true scientific study of the question. The next big space telescope NASA is planning will be called the Habitable Worlds Observatory. The name tells you all you need to know. We’re going all in on the search for life in the Universe because we finally have the capabilities to search for life in the Universe. The giggle factor is finally history.
