In a recent discussion on NewsNation Prime, physicist Avi Loeb raised an intriguing point regarding UFO sightings and their notable absence of sound despite high speeds. This notion challenges conventional understanding of aerodynamics and vehicle design, particularly in how we expect objects moving at such velocities to produce noise. Given the context of the conversation, which revolves around the Pentagon's recent release of declassified UFO files, it prompts questions about what we might be missing in our analysis of these observations.
The Pentagon’s latest release includes declassified documents alongside an audio recording and a transcript from a Project Blue Book presentation by Capt. Edward J. Ruppelt from March 1952. The historical connection to Project Blue Book, which was the U.S. Air Force's program to investigate UFO sightings, adds layers to the current discourse. Loeb’s comments underscore a long-standing mystery surrounding UAPs: if these objects can travel at high speeds without generating sound, what mechanisms are at play? This observation could lend credence to the idea that we might be dealing with technology that defies our current understanding.
Furthermore, the implications of soundless high-speed objects extend beyond just the realm of UFOs. They challenge assumptions about propulsion and energy usage. If traditional physics cannot adequately explain these phenomena, do we need to rethink our understanding of motion and sound in relation to objects we can’t yet fully grasp?
While Loeb's insights provoke thought, we must keep in mind the limitations of the evidence presented. The declassified files may not yet provide a clear picture, and the absence of sound does not automatically equate to an otherworldly origin. This lack of verification creates a gap in our understanding that is crucial to address as we explore these claims further.
The historical context from the Project Blue Book files is also significant. It highlights that these questions about sound and speed are not new; they have been part of the UFO discourse for decades. Yet, even with the current advancements in technology and analysis, we still find ourselves grappling with fundamental questions presented by these sightings.
As we consider Loeb's perspective, it raises an important discussion point: what are the potential implications of soundless high-speed objects for our current understanding of physics and aerodynamics? How might this inform future investigations into UAPs? What would a shift in our understanding mean for the broader conversation about unidentified aerial phenomena?

In a recent livestream from the International Space Station, NASA provided viewers with high-definition views of Earth and the surrounding space. One small detail that caught my attention was the clarity of the images, allowing us to see not just the planet’s surface but also some of the atmospheric phenomena that often go unnoticed. This got me thinking about the potential for unexplained sightings during these streams. In the past, there have been claims of unidentified objects appearing in the background of such broadcasts, raising questions about what might be out there beyond our atmosphere.
There are moments in the livestream where the camera shifts rapidly or the focus changes between various areas of interest, and it's precisely during these shifts that some viewers have reported seeing strange lights or unidentified shapes. I wonder if there’s more to these fleeting images than meets the eye. Could it be a reflection from the ISS itself, or perhaps something else entirely? This leads us to consider the historical context of similar incidents. For example, back in 2009, during a NASA feed, viewers reported a bright object that seemed to dart across the screen. Was it a piece of space debris, or something we still can't explain?
The potential for viewing unexplained phenomena during these high-definition streams is fascinating. With this kind of technology, we open ourselves up to a broader discussion about what may exist beyond our terrestrial knowledge. There are countless reports of UFO sightings and inexplicable occurrences captured on video that could be re-examined with this high-quality data. It raises the question: are we inadvertently capturing evidence of phenomena that we have yet to understand?
As we dive deeper into the possibilities presented by the livestream, I'm curious about the theories surrounding these mysterious sightings. Could the increased clarity of the images lead to a resurgence in interest regarding unidentified aerial phenomena? Furthermore, what can we learn from comparing these live feeds to historical footage of similar occurrences? It seems that the more we investigate, the more questions arise.
In light of all this, I’d love to hear your thoughts on the recent ISS livestream. Have you spotted anything unusual during these broadcasts? What do you think the implications are for our understanding of space and potential extraterrestrial life? Let's explore the unexplained together and see where this journey takes us!

In the recent official NASA live stream featuring high-definition views from the International Space Station, there are moments that spark curiosity and invite speculation about what might be lurking just beyond our view. While the stunning images of Earth provide a breathtaking perspective, it's intriguing to consider how many eyes are on these live feeds, and how many might catch something unusual that we can't explain. This live stream is more than just a viewing experience; it could be a window into the unexplained.
One aspect that stands out is the way these high-definition feeds dramatically enhance our ability to observe both natural phenomena and potential anomalies in real-time. While most viewers might be absorbed in the beauty of our planet, such clarity also raises questions about what else could be seen in the background or on the periphery of the frame. The ISS has been in orbit for over two decades, and the sheer volume of hours of footage accumulated could harbor instances of interest that deserve a closer look. The potential for unidentified aerial phenomena (UAP) to appear in these streams is a tantalizing concept that cannot be easily dismissed.
Throughout the years, there have been historical reports of unidentified sightings from the ISS, including occasional comments from astronauts about odd lights or objects they’ve witnessed during their missions. These testimonies, while often anecdotal, add an intriguing layer to our understanding of what might be happening just beyond the reach of our current knowledge. As the ISS continues to orbit Earth, it serves as an important vantage point from which to observe not only our planet but also the vastness of space, where the unexplained remains a lingering mystery.
In the context of this live stream, it’s worth considering how many of us are actively looking for the inexplicable while gazing at the feed. Are we missing something? The real-time nature of the stream allows for immediate reactions and interpretations of what viewers are witnessing. Are we equipped to recognize the strange among the ordinary, or are the most astonishing phenomena slipping by unnoticed? As more people tune in, the collective observation might yield something unexpected, a moment that could spark discussion or even further investigation.
There are also the claims regarding various objects captured in previous streams, where some viewers have pointed out shapes or lights that do not easily fit into known categories. These instances can be easy to overlook, but they hold potential clues to understanding more about our universe. With the advancement of technology, video quality continues to improve, yet the challenge remains to discern what is truly a phenomenon worthy of our attention from what is merely a trick of light or an atmospheric effect.
As we continue to explore these high-definition views from the ISS, it prompts an open-ended discussion: What do you think we might be missing in these streams? Have you ever caught what seemed like an unexplained object or light on the feed? And with the ongoing interest in UAPs and the quest for understanding alien life, how do you think these live feeds can contribute to our broader search for the unknown?

(Image credit: The Sun)Could artificial intelligence (AI), machine learning (ML), large language models (LLM) or natural language processing (NLP) help us figure out the nature of Unidentified Flying Object (UFOs) or Unidentified Anomalous Phenomena (UAP), by analyzing verbal reports from humans?
Today, I received an email from a group of researchers who stated: “We’ve been working on a machine learning project that classifies reports from the National UFO Reporting Center by narrative “dramaticness,” essentially modeling the language and content of witness reports to distinguish brief, ambiguous observations from highly detailed extraordinary accounts. The pipeline combines structured features, free-text NLP, gradient-boosted models, and an LLM baseline, with explainability built in. We see this as a content-side complement to instrument-side efforts like the Galileo Project: the witness reports are noisy and selection-biased, but they’re also the longest continuous record of public UAP reporting we have, and the language inside them turns out to carry a lot of structure.”
My response clarified the following fundamental points.
In scientific research, low significance data is most abundant but is of little use because it is often swamped by noise. UFOs or UAP are a mixed bag with many reports triggered by human-made or natural phenomena. Humans cannot be trusted as scientific detectors. We need instruments to document the evidence.
This is evident from the legal system, where convicts who were put on death row based on eyewitness testimonies under oath, were later exonerated based on DNA tests. Among 51 cases of death row exonerations, a study posted here found that 45.9% involved informants, while 25.2% involved erroneous eyewitness identification. The same level of misinformation is also evident in common reports on car accidents, where testimonies are often full of imagined narratives and wishful thinking. Stories told by different people about the same car accident are different and sometimes contradictory. Given that there is only one physical reality, they cannot all be correct. Ambiguities are best resolved not by AI/ML/LLM/NLP systems analyzing verbal testimonies, but rather by multiple video cameras observing the car accident.
Since humans know about each other’s story, their narratives are often interwoven and correlated. The fundamental question is whether any of them is right. This is well known to FIFA (Fédération Internationale de Football Association), the soccer worldwide organization. Instead of consulting the goalkeeper or the numerous fans in the audience and using AI/LLM to sort through their narratives, FIFA uses advanced camera-based technologies, including Goal-Line Technology (GLT) and Video Assistant Referee (VAR), to confirm goals, offsides, and fouls. GLT uses 14 high-speed cameras to confirm if the ball crosses the line and sends a signal to the referee within one second, while VAR reviews video footage for overall accuracy.
We can spend a lifetime chasing ghosts based on verbal reports or low-quality data. The Galileo Project under my leadership is focused on getting high-quality data from multiple observing directions, allowing us to infer the distance, velocity and acceleration of objects in the sky. Without distance measurements, it is difficult to assess how anomalous a moving object is. Having a lot of uncertain information is not of interest to the Galileo Project, irrespective of how advanced the AI/ML system that analyzes it is.
On April 17, 2026, President Trump announced in a speech, accessible here, that the first release of classified UFO files will be coming out very soon. As I discussed in a previous essay, posted here, the question is whether the released videos will be the most intriguing ones. Being flooded by blurry videos with no information about the distance of UFOs from the camera will not resolve ambiguities about whether they deviate from the performance envelope of human-made technologies.
When information is limited, intelligence has limited powers. It matters less how advanced the AI/ML/LLM/NLP being used is. What matters the most is the quality of the data. A picture is worth a thousand words. For the same reason, high quality data is worth a thousand LLMs.

(Image credit: Getty/Futurism)One of the surprising anomalies of 3I/ATLAS is its exceedingly high fraction of deuterium, amounting to one deuterium (D) in 100 hydrogen (H) atoms in water (as reported here) and one deuterium in 30 hydrogen atoms in the organic molecule of methane (as reported here). The latter D/H fraction of 3.3% is a thousand times above the average cosmic value elsewhere in the Universe.
During the Manhattan Project, Edward Teller raised the speculative possibility that the fireball from an atomic bomb explosion might ignite the atmosphere by triggering a fusion reaction of nitrogen (14N) nuclei (as described here). In response, Hans Bethe calculated that ignition of the Earth’s atmosphere or the oceans was extremely unlikely because of radiative losses. A 1946 report, authored by Emil Konopinski, Cloyd Marvin Jr. and Edward Teller (accessible here), concluded that “whatever the temperature to which a section of the atmosphere may be heated, no self-propagating chain of nuclear reactions is likely to be started.”
In 1948 Konopinski and Teller published a paper (accessible here) with the first theoretical prediction for the fusion probability of two deuterium nuclei as bomb fuel. Their calculation motivated the development of the hydrogen bomb in two steps. First, the ignition of a plutonium bomb generates high temperature and density conditions, which in the second step trigger the fusion of deuterium fuel.
The fear of triggering a chain reaction remained a concern throughout the entire nuclear weapons test program, especially regarding the possibility that powerful underwater tests of hydrogen bombs might ignite oxygen (16O) atoms in water. Both theoretical and experimental data alleviated these concerns.
The nuclear age considerations led to the development of nuclear astrophysics, based on the realization that fusion of light elements powers stars. Deuterium fusion was of particular interest for the thermonuclear weapons community around Edward Teller, but also of great interest for understanding how low-mass stars shine.
Fast forward to a month ago: March 20, 2026, when a preprint (accessible here) reported that the interstellar object 3I/ATLAS shows an unexpectedly high deuterium abundance of D/H = (3.31 ± 0.34)% for methane. This discovery immediately raised the following question in my mind:
If an atomic bomb were to explode inside 3I/ATLAS, would it trigger a chain reaction of deuterium, generating a spark that ignites 3I/ATLAS into a gargantuan atomic bomb?
This is not a completely hypothetical question. Following the 1994 Shoemaker-Levy 9 comet impact on Jupiter, Edward Teller proposed to protect Earth from similar impacts by designing a nuclear explosive device equivalent to a gigaton of TNT, roughly the kinetic energy of a kilometer-diameter asteroid (as discussed here and here).
This brings me back to my question: If 3I/ATLAS was heading towards Earth and humanity decided to detonate Teller’s envisioned device at its center in order to decimate it, would the device ignite the deuterium-rich nucleus of 3I/ATLAS? If so, how much energy would be released in the resulting nuclear explosion of 3I/ATLAS?
Given that the minimum mass of 3I/ATLAS is 160 million metric tons (as calculated in a paper that I co-authored with Valentin Thoss and Andi Burkert, accessible here), the energy released by fusion of its entire deuterium content would be 10 teratons of TNT. This is about 200,000 times bigger than the largest nuclear explosion ever triggered on Earth — the Soviet Union’s Tsar Bomba, which released about 50 megatons of TNT on October 30, 1961.
If Teller’s nuclear device were to ignite a deuterium chain-reaction at the center of 3I/ATLAS, it would serve as a match that lights a fireball with 10,000 more energy!
My simple back-of-the-envelope calculation before my morning jog at sunrise, indicates that radiative losses would not have saved us from a fusion chain reaction inside 3I/ATLAS.
For an opaque object at solid density like 3I/ATLAS, radiative losses occur at the surface before the object disintegrates. My calculations imply that the explosion triggers by Teller’s device would have disintegrated 3I/ATLAS over a hundredth of a second. In order for the radiative losses to compete with the huge energy released, the surface temperature would have had to rise up to a few million degrees. This, in turn, implies an even higher interior temperature — at which deuterium ignites. This means that exploding Teller’s device deep inside an interstellar object like 3I/ATLAS could ignite a self-sustained D-D chain reaction and a gargantuan nuclear explosion in our cosmic backyard.
My preliminary estimate suggests that we should be careful in using Teller’s device for planetary defense. If we ever discover an interstellar object similar to 3I/ATLAS heading towards Earth, we will need to come up with an alternative, less explosive protective measure.
Here’s hoping that we will never face that risk.
