What can the history of science tell us about the world we live in today and where we might be headed tomorrow? To find out, Dr. Charles Liu and co-host Allen Liu welcome historian of science Rebecca Charbonneau, PhD from the American Institute of Physics and the National Radio Astronomy Observatory with expertise in radio astronomy and the search for extraterrestrial intelligence (SETI).
This episode kicks off with Allen and Chuck talking about January’s Lunar Occultation of Mars. You can see a photo taken by Chuck on our YouTube Community tab.
And then it’s time for today’s joyfully cool cosmic thing: a recent paper in the Astrophysical Journal Letters confirming there are galaxies that were fully formed just 400 million years after The Big Bang. Chuck, who studies galactic evolution, tells us why this changes our understanding of galaxy formation. Rebecca talks about how new ideas can be controversial and how personalities, politics and cultures can impact the evolution of science. She brings up the current controversy in astronomy concerning the locations of terrestrial telescopes and the tension between scientific and cultural imperatives. She also recounts seeing people in Russia wearing NASA t-shirts and explains how NASA understood the importance of controlling the narrative, even inviting Norman Rockwell to popularize the space program.
Our first question comes from Pablo P. on Patreon, who asks, “Can humanity be destroyed by AI powered by quantum computing?” Rebecca explains how during the Cold War, scientists on both sides engaged in “science diplomacy” that helped lower tensions. She applies this thinking to AI, pointing out that while a “Terminator-like” scenario is unlikely, public concern is causing the tech world to confront and grapple with real threats from AI like biases in hiring algorithms.
Allen, a mathematician who writes about AI professionally, addresses whether AI powered by quantum computing is more dangerous than AI in general. Rebecca shares the terrifying story of a Soviet nuclear submarine and the US navy during the Cuban Missile Crisis that nearly started a nuclear war. The dissenting actions of a single officer named Vasily Arkhipov made the difference, and she wonders if AI would have made the same decision based on the available data.
For our next question, we return to our Pablo P. from Patreon for his follow up: “How [do] we answer the question about whether or not we are engaging in self-destructive behavior?” Chuck and Rebecca discuss the confluence of astronomy and the military, and how the history of the SETI program highlights their shared concerns. You’ll find out what the Drake Equation has to do with concepts like The Great Filter. Science, she reminds us, is a tool to try to get closer to the truth, but it’s not always perfect in pointing out whether what we’re doing is safe or potentially self-destructive.
Then we turn to Rebecca’s other big passion, art history and the window into the human experience that art provides. Charles brings up The Scream by Edvard Munch and the fact that it’s actually a depiction of a real atmospheric event. Rebecca talks the use of fractal studies to determine the authenticity of Jackson Pollock art. She also explores the artistic value of scientific artifacts like the controversial plaque attached to Pioneer 10 depicting a naked man and woman, and the interstellar Arecibo Message, sent by Frank Drake in 1974. You’ll even hear how Frank worked himself into the message and what that has to do with Albrecht Durer’s self-portrait painted in the year 1500.
Finally, we turn to what Rebecca’s been up to recently. Her new book Mixed Signals came out in January of this year. Keep up with her on her website at and follow her on X @rebecca_charbon and on BlueSky @rebeccacharbon.bsky.social.

The Burden
The Burden is a documentary series that takes listeners into the hidden places where justice is done (and undone). It dives deep into the lives of heroes and villains. And it focuses a spotlight on those who triumph even when the odds are against them. Season 5 - The Burden: Death & Deceit in Alliance On April Fools Day 1999, 26-year-old Yvonne Layne was found murdered in her Alliance, Ohio home. David Thorne, her ex-boyfriend and father of one of her children, was instantly a suspect. Another young man admitted to the murder, and David breathed a sigh of relief, until the confessed murderer fingered David; “He paid me to do it.” David was sentenced to life without parole. Two decades later, Pulitzer winner and podcast host, Maggie Freleng (Bone Valley Season 3: Graves County, Wrongful Conviction, Suave) launched a “live” investigation into David's conviction alongside Jason Baldwin (himself wrongfully convicted as a member of the West Memphis Three). Maggie had come to believe that the entire investigation of David was botched by the tiny local police department, or worse, covered up the real killer. Was Maggie correct? Was David’s claim of innocence credible? In Death and Deceit in Alliance, Maggie recounts the case that launched her career, and ultimately, “broke” her.” The results will shock the listener and reduce Maggie to tears and self-doubt. This is not your typical wrongful conviction story. In fact, it turns the genre on its head. It asks the question: What if our champions are foolish? Season 4 - The Burden: Get the Money and Run “Trying to murder my father, this was the thing that put me on the path.” That’s Joe Loya and that path was bank robbery. Bank, bank, bank, bank, bank. In season 4 of The Burden: Get the Money and Run, we hear from Joe who was once the most prolific bank robber in Southern California, and beyond. He used disguises, body doubles, proxies. He leaped over counters, grabbed the money and ran. Even as the FBI was closing in. It was a showdown between a daring bank robber, and a patient FBI agent. Joe was no ordinary bank robber. He was bright, articulate, charismatic, and driven by a dark rage that he summoned up at will. In seven episodes, Joe tells all: the what, the how… and the why. Including why he tried to murder his father. Season 3 - The Burden: Avenger Miriam Lewin is one of Argentina’s leading journalists today. At 19 years old, she was kidnapped off the streets of Buenos Aires for her political activism and thrown into a concentration camp. Thousands of her fellow inmates were executed, tossed alive from a cargo plane into the ocean. Miriam, along with a handful of others, will survive the camp. Then as a journalist, she will wage a decades long campaign to bring her tormentors to justice. Avenger is about one woman’s triumphant battle against unbelievable odds to survive torture, claim justice for the crimes done against her and others like her, and change the future of her country. Season 2 - The Burden: Empire on Blood Empire on Blood is set in the Bronx, NY, in the early 90s, when two young drug dealers ruled an intersection known as “The Corner on Blood.” The boss, Calvin Buari, lived large. He and a protege swore they would build an empire on blood. Then the relationship frayed and the protege accused Calvin of a double homicide which he claimed he didn’t do. But did he? Award-winning journalist Steve Fishman spent seven years to answer that question. This is the story of one man’s last chance to overturn his life sentence. He may prevail, but someone’s gotta pay. The Burden: Empire on Blood is the director’s cut of the true crime classic which reached #1 on the charts when it was first released half a dozen years ago. Season 1 - The Burden In the 1990s, Detective Louis N. Scarcella was legendary. In a city overrun by violent crime, he cracked the toughest cases and put away the worst criminals. “The Hulk” was his nickname. Then the story changed. Scarcella ran into a group of convicted murderers who all say they are innocent. They turned themselves into jailhouse-lawyers and in prison founded a lway firm. When they realized Scarcella helped put many of them away, they set their sights on taking him down. And with the help of a NY Times reporter they have a chance. For years, Scarcella insisted he did nothing wrong. But that’s all he’d say. Until we tracked Scarcella to a sauna in a Russian bathhouse, where he started to talk..and talk and talk. “The guilty have gone free,” he whispered. And then agreed to take us into the belly of the beast. Welcome to The Burden.
