There has been increased interest in unidentified flying objects (UFOs) ever since the Pentagon’s 2021 report revealed what appears to be anomalous objects in US airspace, dubbed unidentified aerial phenomena (UAP). Fast forward to 2023, and Nasa has already formed a panel to investigate the reports and appointed a director for UAP research.

A newly founded Pentagon desk has also released footage of mysterious metallic orbs. What is perhaps most remarkable is that David Grusch, a former intelligence officer, testified under oath before the US Congress, stating that he had interviewed around 40 people involved in secret programmes dealing with crashed UFOs.

I am interested in searching the sky for alien, physical objects which may one day tell us whether we are alone in the galaxy. Consider this: within our own Milky Way galaxy, there are 40 billion Earth-sized, potentially habitable planets.

Human ingenuity has enabled us to engineer and launch probes like Voyager and Pioneer, capable of reaching the closest stars. We’ve initiated efforts such as the Breakthrough Starshot programme which aims to reach nearby star Alpha Centauri in just a few decades by exploring innovative propulsion methods. Sending a probe may be more economical than sending out radio or laser communication if there is no need to hurry.

If humans can send a probe to another star, why couldn’t another civilisation send a probe to our Solar System? Such a probe could make it to the main asteroid belt and lurk on an asteroid.

Or, it could make its way to the Earth, entering our atmosphere. If observed, it would be branded as a “UFO”. A civilisation capable of producing and sending probes could dispatch millions of them on exploratory missions throughout our galaxy.

Some may argue that such probes could only exist if they adhere to the laws of physics and engineering as we understand them today. However, humanity is a relatively young civilisation, and our knowledge is constantly evolving.

While humans have dreamt of flying for millennia as we gazed at the skies, it has only been 120 years since the Wright brothers achieved the first powered flight. That’s about as long ago as Albert Einstein published his theory of special relativity.

Is it really so difficult to imagine that a civilisation that is hundreds of thousands years older than ours might have learned more about the laws of physics or developed a few more engineering tricks?

If a civilisation were to evolve into artificial intelligence (AI), it might survive for millions of years. This could mean it would casually regard slow to a neighbouring star as nothing more than a leisurely stroll.

That said, few astronomers felt impressed by the US Navy videos or government reports. We need significantly better evidence and data than what has been presented so far.

Unveiling UFOs

How can we test whether there are extra terrestrial probes near Earth, and whether they can be tied to the possible UFO phenomenon? There are many options. Analysing materials from potentially crashed UFOs could give irrefutable proof. This would require state-of-the-art techniques to determine if these wrecks exhibit exotic or distinctly different characteristics of manufacture.

Obtaining such exotic samples, if they indeed exist, may prove challenging – they are rumoured to be in the hands of private companies. But newly proposed legislation might offer a solution to that problem in United States by mandating that all artificial materials from any non-human intelligence be surrendered to the US government.

In the projects I lead, we are searching for artificial non-human objects by looking for short light flashes in the night sky. Short flashes typically occur when a flat, highly reflective surface — such as a mirror or glass — reflects sunlight. It could, however, also result from an artificial object emitting its own internal light.

Such short light flashes sometimes repeat and follow a straight line as the object tumbles in space during its orbit around the Earth. This is why satellites often appear as repeating light flashes in images.

Historical photographic plates taken before the launch of Sputnik 1 in 1957 have revealed the presence of nine light sources (transients) that appear and vanish within an hour in a small image, defying astronomical explanations. In some cases, the transient light sources are even aligned, just like when short flashes come from moving objects.

The most recent finding of this kind shows three bright stars in an image dated July 19, 1952 (coincidentally, the same time as the famous Washington UFO flyovers). The three stars were never seen again.

Searching for alien probes in the modern night sky presents a serious but necessary challenge. A new research programme, known as ExoProbe, searches for short light flashes from potential alien objects with the help of multiple telescopes.

To verify the authenticity of each flash, it must be observed in at least two different telescopes. Since these telescopes are separated by hundreds of kilometres, any light flash caused by an object within the inner Solar System enables the measurement of parallax — the apparent shift in the position of an object as seen from two different points — and the calculation of the distance to the object.

The ExoProbe project also uses its own methods to filter out light flashes from the millions of space debris fragments and thousands of satellites cluttering the sky. By adding a telescope taking real-time spectra (the wavelength distributions of the light) of the objects in a wide field, you can analyse the transients before they vanish into nothingness.

Finally, increasing the number of telescopes further enhances accuracy in measuring parallax and determining the actual three dimensional location of the object. Ultimately, the goal is to identify any potential alien object and bring it back to Earth for further study.

Some 60 years of searches for extraterrestrial civilisations in the radio frequencies have yielded no candidates whatsoever. We find ourselves at a moment in time when new paths must be explored. That means we can finally focus our attention closer to home. Regardless of the outcome, this journey is certainly an homage to our insatiable curiosity.

airships

In the late 19th century, America was buzzing with the thrill of innovation and exploration. However, amidst the technological advancements, an inexplicable phenomenon began to capture the imagination of many: mysterious airships sighted across the sky. This captivating mystery still puzzles historians and enthusiasts today, raising questions about whether they were mere figments of imagination, hoaxes, or something far more otherworldly.

The Birth of the Mystery

The saga of the mystery airships began in 1896 when reports of strange airships started to emerge from various locations in the United States. From California to Texas, witnesses described seeing cigar-shaped vessels flying through the night sky, illuminated by bright lights. Initial sightings created a flurry of excitement and speculation—newspapers quickly picked up the stories, printing illustrations and accounts that fueled the imaginations of readers.

Witness Accounts: Fact or Fiction?

Witnesses reported diverse descriptions of these airships. Some claimed the vessels hovered silently, while others insisted they produced loud noises that resembled the sounds of machinery or engines. People recounted instances of the airships being seen low enough to see their intricate details, leading many to ponder their origin.

One of the most famous sightings occurred in November 1896 when a newspaper reported that the airship was spotted over Sacramento, California. The pilot was said to have communicated with stunned citizens below, declaring his craft had been developed by a local inventor. Reports flooded in from other areas, each new sighting adding layers to the growing enigma.

Theories and Speculation

As excitement grew, so did the range of theories about the identity of the airships. Some suggested they were the result of secretive military testing, while others posited that they were experimental aircraft developed by inventors hoping to capitalize on the burgeoning aerospace industry. Conspiracy theories soon emerged, suggesting the airships were extraterrestrial craft, aliens visiting Earth long before modern UFO sightings became popular.

Another prevalent theory was that the airships were elaborate hoaxes created by pranksters or con artists. The media of the time jumped at the chance to sensationalize these stories, leading to speculation and possibly embellished accounts. Whether the sightings had factual bases in truth or were mere products of an imaginative society was a question many grappled with.

The Decline of the Phenomenon

By the turn of the century, reports of the mysterious airships began to wane. As the 20th century ushered in advancements in aviation technology, the public’s focus shifted toward real developments in flight, including the Wright brothers’ first powered flight in 1903. Interest in the mystery airships diminished, becoming a curious footnote in UFO and aviation history.

Legacy and Cultural Impact

Even today, the legacy of the mystery airships endures in popular culture. They have been the subjects of countless books, documentaries, and podcasts exploring the thin line between reality and imagination. The 1896 sightings continue to be cited in discussions about early UFOs, serving as a fascinating precursor to the modern fascination with unidentified flying objects.

As we unravel this historical enigma, we are reminded of humanity’s insatiable curiosity about the skies above. Whether rooted in fact or fictional fantasy, the mystery of the 1896 airships still invites exploration into the unexplained and provokes questions that resonate through time.

Understanding paranormal beliefs and conspiracy theories isn’t just about misinformation – this course unpacks the history

Published

on

Uncommon Courses is an occasional series from The Conversation U.S. highlighting unconventional approaches to teaching.

Title of course:

“Investigating the Paranormal”

What prompted the idea for the course?

My training and professional work have been in Mesoamerican archaeology, but I’ve had a lifelong fascination with paranormal concepts. In fact, I considered studying the UFO community for my doctoral research in cultural anthropology.

I eventually fused these two interests in my book “Spooky Archaeology: Myth and the Science of the Past,” which examines why archaeology shows up so much in ideas about the mysterious and weird. Most people are familiar with pop culture characters like Indiana Jones seeking magical artifacts. Perhaps less immediately obvious is just how common archaeological topics are in paranormal and conspiracy culture.

The popularity of paranormal ideas – from television shows and thousands of podcasts to UFOs on the front page of The New York Times and in government investigations – made it clear that a course on paranormal culture would be an excellent way for students to get a taste of social science research.

What does the course explore?

The material begins with premodern ideas of magic, myth and metaphysics. The narrative that “Western” societies tell of the development of the modern world is that the Enlightenment cast off supernatural thinking in favor of science. The historical reality, however, is not so simple.

As science based on observation of material evidence emerged in the 17th through 19th centuries, so did a paranormal worldview: theories about a nonmaterial or hidden reality beyond the mundane, from monsters to psychic powers. Some of these ideas were tied to older religious notions of the sacred or strange but not divine phenomena. Others were new – particularly those suggesting the hidden existence of prehistoric extinct creatures or lost cities.

In either case, the key element was that proponents of these ideas often tried to support their existence with the kind of evidence used in science, though their “proofs” fell short of scientific standards. In other words, the paranormal is in conflict with the knowledge and worldview of modernity but also attempts to use the concepts of modernity to oppose it.

The class examines how this tension produced 20th century “-ologies” like parapsychology, which examines evidence for consciousness beyond matter, and cryptozoology, which searches the ends of the Earth for creatures tied to the mythic past. We also learn about UFOlogy, whose proponents have collected alleged contacts with technology and beings from beyond this world ever since the Cold War, as great earthly powers filled the skies with secretive hi-tech aircraft and spaceships.

As the class concludes, we examine how the “-ologies” declined after the Cold War, alongside the cultural capital of science, whose height of public respect was in the mid-20th century. Since then, proving the existence of paranormal things to institutional scientists has become less important in paranormal communities than promoting them to a broader public.

Why is this course relevant now?

Beyond public interest in paranormal topics, the paranormal is entwined with sociocultural forces that have dramatically increased the role of conspiracy rhetoric in the United States and elsewhere. At their core, both types of belief claim to have figured out some kind of supposedly hidden knowledge.

Furthermore, the conspiracy theories that are now commonplace in American political discourse are more rooted in paranormal ideas than in previous decades. Conspiracy theories about the JFK assassination or even 9/11 were still largely within the materialist realm. People argued that “the truth” had been covered up, but their arguments did not rely on metaphysical ideas. Today, major conspiracy theories involve secret cabals, mystical symbols and code words, demonic forces and extraterrestrial entities.

What’s a critical lesson from the course?

Evidence must be interrogated on its own, regardless of whether it fits your perspective. I find time and again that students have a hard time approaching evidence without bias, whether that bias is conscious or not: “knowing” that something must be true, or must be absurd.

One person apparently makes a death bed confession of faking a famous Loch Ness Monster photo, pleasing skeptics. Another claims to have seen a Bigfoot at close range, pleasing believers. Without further evidence, both are stories: no more, no less.

The issue isn’t to draw an equivalence between the bigger concepts. Not all narratives are equally well-founded. But students learn how to collect evidence, rather than simply rely on their gut sense of what is plausible or not.

What will the course prepare students to do?

This course is meant to help students discern useful and reliable information about claims and events, separating them from irrelevant or inaccurate narratives or sources. The goal is not just “critical thinking” aimed at combating disinformation, though that is part of what they should learn. Students practice evaluating evidence but also develop an approach for analyzing and understanding phenomena behind it: how factors like history, culture and institutions of authority, such as science and government, shape what people trust and what they believe.

Mysterious Lights Over Oregon: Pilots Report Unusual Aerial Phenomena

Published

on

Oregon

This past weekend, the skies of Oregon became the backdrop for an extraordinary event that has both puzzled and dazzled observers. At least four commercial pilots reported encountering unexplained bright lights displaying incredible speeds and erratic movements, renewing interest and debate about aerial phenomena.

The Encounter Details

The first report came from a pilot operating an air ambulance who described a startling experience. A bright, red light zoomed towards his Life Flight plane, only to reverse direction and head back towards the Pacific Ocean at bewildering speeds. The event left the pilot and his crew astounded by the light’s velocity and abrupt maneuvers.

Meanwhile, the pilot of a United Airlines flight over Eugene also reported seeing multiple mysterious objects. These unidentified lights moved vertically and horizontally in patterns that defied easy explanation, with no evidence of military activity in the area at the time.

Adding to the intrigue, the Life Flight pilot noted that one of the lights engaged in a corkscrew pattern, an observation that was corroborated by the aircraft’s collision avoidance system. Air traffic control, maintaining a cautious approach, authorized the pilot to maneuver as necessary to maintain safety.

Visual Evidence and Continued Sightings

Throughout these encounters, several pilots managed to capture brief video clips. These clips, although hard to discern due to the dark conditions, show glimpses of the unusual red, circular lights. Another report from two Horizon Airlines pilots further confirmed that whatever was out there wasn’t isolated to a single incident or observer.

Experts Weigh In: Possible Explanations

In the wake of these mystifying sightings, experts have been quick to offer explanations. Douglas Buettner, a scientist who has researched similar incidents, suggests that these lights could likely be flares from Starlink satellites. Starlink, a constellation designed by SpaceX to provide global broadband coverage, has been known to produce vivid optical flares when its panels reflect sunlight.

Buettner’s research, which includes previous pilot reports and observations, supports the idea that this natural reflection of sunlight could explain the phenomena observed. However, he also admits the current data is insufficient to conclusively rule out other possibilities.

Government and Public Response

Following these reports, the Federal Aviation Administration (FAA) confirmed the sighting of unidentified lights by a pilot, although they have not commented further. In a recent Senate hearing, the Pentagon’s director overseeing unidentified anomalous phenomena indicated a spike in such reports since the launch of satellite constellations like Starlink, underscoring the growing interest and concern regarding these observations.

The Broader Implications

While the most likely explanation for these mysterious lights points to satellite flares, the repeated occurrences of such phenomena continue to stir the public’s imagination and scientific curiosity. As we advance in our technological capabilities, the skies above us grow increasingly populated with human-made objects that can sometimes return to us as bewildering spectacles.

In either case, these events serve as a reminder of the vast and unexplored frontiers above us and the ever-present human quest for understanding the mysteries of our universe. Whether they turn out to be mundane or truly otherworldly, the skies over Oregon this weekend have given us all something to ponder and marvel at.
