The Cosmic Tusk

In 2017, geochemist Dr. Mark Defant appeared on the Joe Rogan podcast alongside Michael Shermer specifically to argue against Graham Hancock's lost civilisation hypothesis and, by extension, to express scepticism toward the Younger Dryas Impact Hypothesis. He had been asked to join the show the night before, spent that evening reading up on the subject, and went in unconvinced.

What followed over the next few years was something that almost never happens in public scientific discourse. Defant went back and actually read the papers. He worked through the data accumulated by the Comet Research Group over more than a decade - the micro spherules, the platinum group elements, the nano diamonds, the fire markers, the population drop-offs in the archaeological record. And then he said, out loud, that he had been wrong.

He is now a voluntary contributor to the Comet Research Group's active research, joining weekly sessions with Allen West, Malcolm Lecompte, and Dallas Abbott to analyse samples under electron microscopes. He describes the experience of looking at the spherules and the melted glass as making it hard to imagine any other conclusion. George Howard documented the reversal on the Cosmic Tusk blog in a post he titled simply - In Praise of Intellectual Honesty.

Dan Sutton is an autodidact who started with Google Earth and a background in electric universe theory. What he found, and has spent years attempting to disprove, is a scar running from the Taklamakan Desert through the Middle East and into North Africa that he believes marks the entry and exit points of a plasmoid - a self-sustaining electromagnetic structure - that struck the Earth around 12,000 to 13,000 years ago.The Taklamakan Desert, in his model, is the exit wound. The plasmoid did not strike like a conventional impactor. It was not a solid object but a counter-rotating double toroid - a magnetic field structure - whose energy punched through the crust and ejected material outward. The Himalayan mountain range and the raised Tibetan Plateau, Sutton argues, fall precisely within the field lines of the upper toroid. The fluid dynamic patterns visible in the surrounding mountain ranges, and the diamond-shaped resonance formations consistent with supersonic wind events, extend across the entire region.The theory is not yet peer reviewed and Sutton is the first to acknowledge the challenges of presenting it. However, the more he has tried to disprove it, the more the geography has continued to fit.

Andrew Gallimore is a neuroscientist based in Tokyo who studies DMT, not as a drug that causes hallucinations, but as a chemical key that switches the brain's reality channel to something else entirely. In this episode of The Cosmic Tusk podcast, George Howard sits down with him to talk about what that space actually is, why the simplest molecule in nature unlocks the most complex experience ever reported, and what it means that this molecule was scattered across every plant and animal on Earth long before humans figured out how to use it.

In this wide-ranging conversation on the Cosmic Tusk Podcast, host George Howard sits down with geologist and researcher Randall Carlson and Pacific Northwest historian Dan Richards to dismantle some of archaeology's most sacred assumptions.The centrepiece is an Italian engineer's relative erosion study of the Khufu pyramid, one that dates its construction somewhere between 10,000 and 40,000 years ago, with a mean estimate of 25,000 BC. The methodology is elegant and controlled: a documented medieval earthquake 675 years ago stripped the pyramid's casing stones, exposing fresh limestone for the first time. That newly exposed surface shows almost no weathering. The original exterior, open to the elements since construction, shows deep, extensive pitting that requires millennia of heavy rainfall to form, rainfall that Egypt hasn't seen since the green Sahara period, thousands of years before the pharaohs. When you run the ratio, the official date of 2,500 BC doesn't survive the comparison.But the pyramid is only part of the story. Randall presents new terrain analysis pointing to exact impact locations from the Younger Dryas catastrophe, and dismantles the physics of the Missoula ice dam model, an ice structure that would have needed to hold a 2,100-foot hydraulic head, which the tensile strength of ice makes flatly impossible. Dan Richards brings an angle most people have never encountered: thousands of elongated skulls from Pacific Northwest Native American burial sites, systematically looted and quietly erased from the record, alongside tribal flood myths that map almost perfectly onto the Cordilleran deglaciation sequence. And when the Comet Research Group's recent paper retractions come up, all three lay out in plain terms what happens when inconvenient evidence meets institutional gatekeeping.Two of the researchers whose papers anchor this conversation have had their work suppressed, retracted, and ridiculed. The data hasn't changed. The question is whether you're willing to look at it.

Dr. Chandra Wickramasinghe is a cosmologist, astronomer, and mathematician who spent nearly 50 years working alongside Sir Fred Hoyle. Together they published roughly 70 papers in Nature arguing that cosmic dust is biological, that life is a property of the universe itself, and that Earth is a collection plate. None of those papers were ever refuted, they were ignored.

In this episode of The Cosmic Tusk podcast, George Howard sits down with Chandra and his wife Priya for a conversation that covers the science, the suppression, and the personal cost. Arthur C. Clarke shows up on a bumpy prop plane, a fax machine in Cardiff delivers the most important spectrum in modern biology, and there are dust clouds at the Lagrange points that might be listening.

On this episode of the Cosmic Tusk, Dana Kippel (https://studio.youtube.com/channel/UCaDgEYwfJOKMduoLGlXA6NQ) joins George Howard for a wide-ranging conversation about plasma - what it actually is, why it makes up 99.9% of the visible universe, and why so few people seem to know about it.

They dive into:

• Ball lightning and why serious research into it keeps disappearing
• The plasma clouds sitting at the Lagrange points between Earth and the Moon
• Dana's framework of 3D, 4D, and 5D plasma
• The divine feminine as the suppressed counterpart to consciousness
• How ancient mythology may have been encoding plasma physics long before we had a name for it
• What Dana thinks UFO disclosure is getting fundamentally wrong

George also shares his own firsthand experience seeing ball lightning as a kid!

What if ancient civilizations on opposite sides of the world were far more connected than mainstream archaeology admits, and the key to understanding why lies in galactic cycles?

Lance Weaver joins George Howard on the Cosmic Tusk podcast to lay out the evidence for pre-Columbian transoceanic contact, cultural diffusion across ancient civilizations, and a bold geological framework linking polar excursions, galactic filaments, and 3,000-year disaster cycles to Earth's shifting spin axis.

Polish researcher and author Aleksander Cieszkiewicz joins George Howard to explore ancient kings lists, lost civilizations, and the metaphysical roots of human history. From Plato’s Atlantis to the dreamlike visions of ancient gods, the conversation tracks the threads of myth, memory, and science across thousands of years.

Aleksander shares insights from his book Déjà Vu: Has Everything Already Been?, drawing on Mesopotamian texts, Egyptian cosmology, and new perspectives on consciousness, catastrophe, and the forgotten cycles of time that may shape humanity’s story far more than we realize.

What qualifies as real evidence? Where do we draw the line between scientific skepticism and open inquiry?

Michael Shermer ⁨(https://studio.youtube.com/channel/UCfsuI3-92QNO3DVy06PO9wg) joins George Howard on the Cosmic Tusk podcast for a candid exchange on the Younger Dryas Impact Hypothesis, confirmation bias, and the philosophical divide between mainstream science and alternative researchers.

It’s a rare discussion that digs beneath the surface, not just about data, but how we interpret it, defend it, or dismiss it.
