The Skeptics' Guide to the Universe

The Skeptics Guide #1063 - Nov 22 2025

November 22, 2025

Key Takeaways Copied to clipboard!

  • Dubai is actively positioning itself as a 'city of the future' by investing heavily in technology and attracting talent, emphasizing the need for skepticism to prevent pseudoscience from infiltrating these advancements. 
  • The current AI boom is characterized by massive investment and speculation far outpacing reality, creating a financial bubble that could lead to a market correction, though the underlying technology is real and transformative. 
  • The Dumbest Thing of the Week in *The Skeptics' Guide to the Universe* #1063 is awarded to NBC's *Today Show* for promoting the ongoing, debunked search for Noah's Ark near Mount Ararat, illustrating the cyclical nature of media coverage for pseudoscientific claims. 
  • Sonic booms are continuous shock waves generated by multiple surfaces of a supersonic aircraft, and engineers are shaping the downward cone of these waves to create a quieter 'sonic thump' for potential commercial supersonic flight. 
  • A new blood test claiming to confirm Chronic Fatigue Syndrome (ME/CFS) is likely overhyped because syndromes are complex, and the study failed to compare results against other chronic illnesses to prove specificity. 
  • The definition of tool use is subjective, and pulling an object (like a net) attached to a food source does not necessarily qualify as true tool use if the animal did not deploy or craft the object. 
  • The Science or Fiction segment revealed that creating immortal cow cells without genetic modification (Item 3) and developing a polymer film 10,000 times less gas-permeable (Item 2) are real scientific advancements, while the tenfold increase in cost-competitive bacterial cellulose production for textiles (Item 1) was fiction. 
  • The discussion emphasizes the humbling realization that one's expertise in one field does not negate profound ignorance in all other areas, a concept often used in lectures. 
  • A significant concern raised in this segment of The Skeptics' Guide to the Universe is the rise of historical denialism, exemplified by recent TikTok trends questioning the existence or circumstances of figures like Helen Keller. 
  • The episode concludes with personal anecdotes, including a humorous recollection of a near-accident caused by invisible ice on a driveway, highlighting the lack of friction in certain conditions.

(00:08:01)
  • Key Takeaway: NBC’s Today Show earned the Dumbest Thing of the Week for covering a new team’s GPR scans claiming evidence of man-made structures at the Mount Ararat Noah’s Ark site, which geological analysis confirms are natural mineral concentrations.
  • Summary: Evan Bernstein presented the Dumbest Thing of the Week concerning a Today Show segment about investigators using Ground-Penetrating Radar (GPR) at Mount Ararat to find Noah’s Ark. Previous geological studies concluded the formation is a natural rock structure composed of volcanic sediment and erosion. The new claims of finding structures like an iron bracket are dismissed as natural mineral concentrations, highlighting the persistence of pseudoscientific searches.

(00:42:07)
  • Key Takeaway: A 2024 systematic review found low-to-moderate confidence evidence that creatine supplementation significantly improves specific cognitive components like memory and processing speed, but shows no consistent benefit for overall cognitive or executive function in healthy individuals.
  • Summary: Creatine monohydrate is theorized to boost brain energy (ATP) via phosphocreatine stores, presenting a plausible biological mechanism. However, a review of 16 clinical trials indicated mixed results, suggesting benefits only in specific areas like memory, not overall cognition. The authors concluded that the evidence is preliminary and low confidence, suggesting it may only offer limited benefit under stress, such as sleep deprivation, rather than acting as a general ‘smart pill’.

(00:52:25)
  • Key Takeaway: NASA and Lockheed Martin’s X-59 test plane is specifically designed to mitigate the disruptive sonic boom of supersonic flight to a ‘sonic thump’ to enable the eventual lifting of the U.S. law banning civil supersonic flight over land.
  • Summary: The X-59 is an experimental plane designed to fly faster than sound while producing only minor sonic thumps instead of the disruptive sonic booms that grounded the Concorde due to public backlash and potential minor damage. The continuous nature of the sonic boom, which occurs as long as the plane exceeds Mach 1, was clarified as a common misconception. A key goal of this research is to change current aviation laws that prohibit civil supersonic flight over U.S. airspace.
Supersonic Flight and Sonic Booms

(01:00:00)
  • Key Takeaway: The sonic boom is a continuous event caused by the merging of multiple shock waves into an expanding cone behind the aircraft, which is heard when the cone intersects the ground.
  • Summary: Supersonic flight transitions from smooth subsonic pressure waves to abrupt shock waves, which merge into an expanding cone behind the plane. This cone is formed by shock waves generated by the nose, wings, and tail surfaces. When this cone intersects the ground, the resulting pressure change is heard as a sonic boom.

(01:03:02)
  • Key Takeaway: Engineers aim to convert the sonic boom into a ‘sonic thump’ by sculpting the downward portion of the shock wave cone into smaller, gentler waves spread out over time.
  • Summary: To achieve a ‘sonic thump,’ engineers sculpt the downward shock wave cone into gentler, more spread-out waves, aiming for a sound comparable to a car door slamming. The experimental X-59 aircraft, featuring a long, chisel-shaped nose, recently completed a successful initial flight test at subsonic speeds. Future tests will assess the thump’s perceived tolerance over populated areas to potentially pave the way for commercial supersonic travel over land.
Chronic Fatigue Syndrome Test Analysis
Copied to clipboard!
(01:08:07)
  • Key Takeaway: A reported 96% accurate blood test for ME/CFS, based on epigenetic profiling, is preliminary because it was only compared against healthy controls, not other chronic illnesses.
  • Summary: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is recognized as a distinct physiological disorder involving immunology, neurology, and metabolic dysfunctions, though it is likely not one single disease. The new test examines DNA folding signatures in immune cells, but its validity hinges on showing specificity against other conditions like rheumatoid arthritis or Parkinson’s disease, not just healthy individuals. Ultimately, the test’s clinical value depends on whether it predicts useful treatment outcomes rather than just assigning a label.
Who’s That Noisy Winner Revealed

(01:21:41)
  • Key Takeaway: The sound played for ‘Who’s That Noisy’ was correctly identified by a listener as an F-16 firing its M61 Vulcan 20-millimeter auto-cannon during a strafing run.
  • Summary: Despite many guesses, including the A-10 Warthog, the winning submission identified the sound as an F-16 firing its rotary cannon. The listener who submitted the sound, Mike, was the pilot flying the aircraft during the recording. The sheer power of these types of aircraft cannons is noted as being quite impressive.
Wolf Tool Use Definition Debate
Copied to clipboard!
(01:29:10)
  • Key Takeaway: Pulling a submerged net attached to a food source does not constitute true tool use because the wolf is merely retrieving food attached to an object, not deploying or crafting the object for manipulation.
  • Summary: The definition of tool use, particularly the requirement that the object be ‘unattached,’ is being challenged by a report claiming a wolf used a net to catch crabs. The hosts argue that this behavior is closer to pulling a branch out of the water hoping for food, lacking the intentional deployment or crafting seen in true tool use, such as by chimpanzees. The key distinction is whether the animal is manipulating the object itself or simply pulling on something connected to a reward.
Science or Fiction Results
Copied to clipboard!
(01:36:49)
  • Key Takeaway: Scientists successfully created immortal cow cells without genetic modification via the natural activation of telomerase, and MIT developed a 2D polymer film 10,000 times less gas-permeable than existing polymers.
  • Summary: Item 3, the creation of immortal cow cells without genetic modification, is science; this bypasses GMO regulation and is intended for lab-grown meat production by activating telomerase. Item 2 is also science; MIT created a 2D crystalline polymer film that prevents gas permeation, useful for food preservation or containing hydrogen fuel. Item 1, concerning a tenfold increase in cost-competitive bacterial cellulose production for textiles, was fiction, as the actual innovation involved co-culturing bacteria to produce both cellulose and dye simultaneously.
Expertise and Ignorance Balance

(01:58:48)
  • Key Takeaway: Recognizing one’s profound ignorance across most topics, despite expertise in one area, should serve as a necessary humbling experience for critical thinkers.
  • Summary: When experts encounter discussions about their specialty in lay media, they often find the content cringeworthy because the general population profoundly lacks knowledge. This same dynamic applies inversely to the expert regarding every topic outside their specialization. This realization mandates intellectual humility when evaluating information across diverse subjects.
TikTok Historical Denial Rant
Copied to clipboard!
(01:59:46)
  • Key Takeaway: A growing trend observed in content shared with The Skeptics’ Guide to the Universe involves the outright denial of established historical facts, such as claims that Helen Keller did not exist or was not blind and deaf.
  • Summary: The denial of historical figures like Helen Keller is cited as an example of misinformation spread online, often driven by a narrative that everything previously known is false. The absurdity of denying Keller’s achievements is highlighted by the fact that her fame stems precisely from overcoming those severe sensory disabilities. This pattern suggests a broader, baseless attempt to rewrite established history.
Host Return and Travel Anecdote

(02:01:03)
  • Key Takeaway: A severe driving hazard occurred when a vehicle slid uncontrollably down an icy driveway due to a near-zero coefficient of friction, resulting in a collision with the house.
  • Summary: One host expresses relief at returning home after extensive travel, including a 24-hour journey from Australia. This return was marked by a previous incident where the car slid down a driveway frozen solid with invisible ice. The physics of the incident were characterized by a complete lack of friction, causing the vehicle to coast into the structure.
