Unexplained Starlight Pulses: Is Advanced Tech Operating Covertly in Our Cosmic Neighborhood?

For decades, humanity has peered into the vast darkness between the stars, dreaming of the moment we might detect a sign of intelligence beyond our own. The Search for Extraterrestrial Intelligence (SETI) has long focused on distant radio whispers or powerful laser flashes, while intriguingly, starlight pulses might reveal clues right in our cosmic backyard. But what if the most profound evidence isn’t coming from light-years away? Could it be from our very own cosmic backyard? Recent, startling discoveries from a dedicated optical observatory in Big Bear, California, are forcing us to confront this very question.

In May 2023, retired NASA scientist Richard Stanton, working in Big Bear, California, discovered an unexplained “pulsing” signal from a Sun-like star, HD 89389, in the Ursa Major (Great Bear) constellation. This star is approximately 100 light-years away. The signal was described as two identical and fast pulses occurring 4.4 seconds apart. It was published in the Acta Astronautica scientific journal.

Stanton noted that these pulses were unlike any other signals he’d detected during his 1,500 hours of searching. The signal’s unique pattern has left scientists puzzled. This pattern, consisting of a “brighter-fainter-brighter” sequence, is intriguing to researchers.

“We don’t know what kind of object could produce these pulses or how far away it is. We don’t know if the two-pulse signal is produced by something passing between us and the star or if it is generated by something that modulates the star’s light without moving across the field. Until we learn more, we can’t even say whether or not extraterrestrials are involved!“
– Richard Stanton

Stanton has unveiled a truly perplexing phenomenon: pairs of incredibly fast, identical pulses of starlight. Imagine a star’s brightness undergoing a sudden, dramatic dance. There’s a rapid surge, then a sharp dip, followed by an equally swift return to its original intensity.

This entire sequence unfolds in mere milliseconds. After a brief pause of a few seconds, the exact same intricate pattern repeats. This occurs with precision that defies natural explanation.

Cosmic Code: Unraveling the Twin Pulses

The first captivating instance came from the star HD89389. The near-perfect replication of the “fine-structure” within each pulse wasn’t just intriguing; it screamed of a deliberate, non-random event. Even more chillingly, a deep dive into historical data uncovered an identical pair of pulses from HD217014. This occurred four years prior. This earlier event had been casually dismissed as “birds” – an innocuous explanation that now seems inadequate for such a profound celestial signature.

Not Just Birds: A Galactic Mystery

The implications are staggering. The sheer speed of these light changes immediately tells us one crucial thing: the source cannot be the distant star itself. No known stellar process could cause such rapid, precise fluctuations. This realization narrows the field dramatically. It places the origin of these mysterious flashes much closer to home, likely within our own solar system.

Close Encounter? Tracing the Origin

So, if not the stars, then what? While natural phenomena like unusual atmospheric disturbances or even binary asteroid systems are considered, the precision and repeatable nature of these pulses push scientists towards a more audacious hypothesis. They suspect edge diffraction, a well-understood optical effect. It describes how light bends and creates distinct patterns when passing by a sharp edge. The specific “bipolar” shape of these observed pulses – the characteristic increase, decrease, and subsequent increase in brightness – bears an uncanny resemblance to diffraction patterns expected if starlight interacts with edges of a nearby, opaque object.

Diffraction’s Clue: The Shadow of Something Else

Think of it this way: a previously unknown object, possibly a thin, flat structure or even a ring, momentarily crosses our line of sight to a distant star. As the star’s light skims past one edge, it creates the first pulse. When it passes the other edge, the second identical pulse is generated.

Eyes Wide Open: The Hunt for Hidden Objects

This theory, while still under investigation, ignites a firestorm of possibilities. If these are indeed diffraction patterns, it implies an object’s existence, possibly within our solar system, that is causing these obscurations. What kind of object? And more importantly, who or what created it?

A single telescope, no matter how powerful, can only offer limited clues. It can detect these fascinating anomalies. However, it can’t definitively tell us the object’s precise distance, speed, or true nature. That’s where the future of this extraordinary search comes into play.

The urgent call from the scientific community is for the development of Optical Telescope Arrays (OTAs). Imagine a network of precisely synchronized telescopes, positioned across the Earth. By meticulously measuring the infinitesimal time delays as this object’s shadow sweeps across each individual telescope, scientists could triangulate its position with astonishing accuracy. This method would determine its velocity and perhaps resolve its physical characteristics. This would be a leap from passive observation to active, investigative astronomy.

Beyond the Stars: ETI in Our Backyard?

And here, at the precipice of this discovery, lies the most profound question. If these pulses are confirmed to be caused by an object in our solar system, and if its trajectory suggests it’s not a natural body – what then? Could it be a long-lost piece of cosmic debris or an anomalous natural formation? Or, the thought that sends shivers through us, could this be a sign of extraterrestrial intelligence? Perhaps the ultimate “SETI signal” isn’t a deliberate message beamed across the galaxy. Could it be the unavoidable, accidental, signature of advanced technology operating in our celestial neighborhood?

The Ultimate Question: Are We Witnessing Alien Tech?

The universe continues to surprise us, challenging our assumptions and pushing the boundaries of what we believe possible. These inexplicable starlight flashes are more than just an astronomical curiosity; indeed, they are a cosmic riddle. It could, just possibly, hold the key to answering humanity’s most enduring question: Are we truly alone? The echoes from the void are growing clearer. The potential for a paradigm-shifting discovery has never been more tangible.

The Sagan Paradox, Chapter 1: The Golden Record

Introduction and Carl Sagan’s Early Work

Artwork inspired by Linda Salzman Sagan’s design for the Pioneer plaque, commissioned by NASA: click here view the original design

Carl Sagan (1934–1996) was an American astronomer, astrobiologist, and author. After NASA was founded in 1958, Sagan became a consultant for the agency. His first job involved planning the explosion of an atomic bomb on the moon, the A119 project. Highly controversial, to say the least. In 1961, at the age of 27, he published a study on the atmosphere of Venus. In 1970 he researched the conditions that could lead to the emergence of life in the cosmos on distant planets. To achieve this, he exposed frequently occurring elements to the UV radiation of a young sun and observed how amino acids, the building blocks of life, were formed from them. Carl Sagan became a full professor at the astronomy department at Cornell University. Around this time, talk shows began inviting him as a popular guest to discuss the possibility of extraterrestrial life.

“Hello, Aliens!”: Voyager Probes Get Sagan’s First Broadcast

In 1972 and 1977, Carl Sagan sent the first messages to extraterrestrials into space on the panels of the space probes Pioneer 10 & 11 and the Golden Record of Voyager 1 & 2.

The gold-plated aluminum cover (L) of the Voyager golden record (R) both protects it from micrometeorite bombardment and also provides a key to playing it and deciphering Earth’s location. NASA

It contains greetings and wishes for peace from the people of Earth in 55 languages. Earthlings extend their friendship, wish happiness and health, and express hope to one day meet their cosmic neighbors. They also express the desire for goodwill and harmony among all beings in the universe.

Reference: Golden Record Greetings – NASA Science
Each of the Voyager spacecraft, launched in 1977, carried a golden phonograph record. One of its purposes was to send a message to extraterrestrials who might find the spacecraft as it journeyed through interstellar space.

The greetings are in alphabetical order, from Akkadian (an extinct language for over 2000 years) to Wu Chinese. The inclusion of Akkadian in this earthly record is pretty strange. One day, these transmissions might be intercepted as they pass through space by an alien culture.

Voyager’s ‘Cosmic Map’ Of Earth’s Location Is Hopelessly Wrong

With the help of the included pulsar map, these aliens could potentially find Earth. Pulsars are stars that rhythmically emit radiation, like interstellar lighthouses. We can use them as a cosmic GPS.

Pulsar GPS: Sagan’s Star-Beacon Timecode Reveals 1971 Earth

Over long periods of time, the frequency of a pulsar slows down. Thus the pulsar map designed by scientist Frank Drake and graphic artist Linda Salzman Sagan is not only a determination of the position of our Earth in space, but the map also precisely pinpoints the position of Earth in time: 1971.

What if a prospective alien civilization has or develops the ability to time travel? What would they do with the information provided by our space probes?

Speculation about the subject makes for the greatest sci-fi story ever told. This is particularly true when we consider the included Mesopotamian-language greeting and the Annunaki creation myths—some of which have been popularized by Zecharia Sitchin and others.

Of course, intercepting our space probes is extremely unlikely. It could take millions of years, if at all. But then again, the life expectancy of the Golden Records is 5 billion years.

Posing the Cosmic Question: What Occurs Within a Black Hole?

AI’s Provocative Claim: “Humans Are Ignorant”

Consider the following intriguing questions: What happens to the very dimensions of spacetime inside a black hole? Different responses from an AI highlight both our current understanding—and our limitations.

First Perspective: Continuity of Four-Dimensional Spacetime

One reply asserts that objects falling into a black hole do not lose any dimensions. In this view, spacetime retains its four-dimensional structure (three dimensions of space plus one of time) both outside and inside the event horizon. The singularity—where density becomes infinite—is not actually a state reduced to 1D. Instead, it represents a point where general relativity breaks down after entering a black hole. Although quantum gravity theories such as loop quantum gravity propose alternatives (for instance, “bounces” that avoid the singular state), none of these ideas involve a reduction in the number of dimensions.

Second Perspective: Dimensional Breakdown at the Singularity

A subsequent response from the same AI emphasizes a different perspective. In Einstein’s theory, the singularity is defined as a point of infinite density and extreme spacetime curvature. It is where the equations of general relativity “break down.” In this classical picture, spacetime loses its well-defined four-dimensional structure (3 spatial dimensions plus 1 time dimension). For non-rotating, or Schwarzschild, black holes, the singularity is described as a 0D point. In contrast, for rotating (Kerr) black holes, the singularity takes on the form of a 1D ring.

Reconciling the Contradiction: Artifacts of Mathematical Models

The AI explains these seemingly contradictory responses with a reminder that, in general relativity, the singularity is not a physical object. Instead, it is a mathematical artifact. The labels “0D” and “1D” serve as geometric shorthand—conceptual placeholders that indicate where our classical theories fail. In effect, these designations (“here be dragons”) acknowledge the limits of our current understanding of extreme gravitational environments, especially those involving black holes.

Embracing the Unknown in Theoretical Physics

In summary, one perspective maintains that spacetime remains four-dimensional throughout the journey into a black hole. This is true even as general relativity breaks down at the singularity. Another viewpoint suggests that, near the singularity, the familiar four-dimensional framework is lost. It collapses into a 0D point or a 1D ring depending on the black hole’s rotation. Ultimately, both answers are reminders of the limits of our current theories and the continuing challenge of unifying general relativity with quantum mechanics.

Stephen Hawking’s Insight: Illuminating Our Limitations

An illustrative image from Stephen Hawking’s Reith Lecture on 26 January 2016 further underscores this point. Hawking’s insights remind us that while our current models of black holes capture many aspects of reality, they also expose profound gaps in our knowledge.

Until a successful theory of quantum gravity is developed, these descriptions remain approximations. They reflect human ignorance as much as our understanding.
