Brooks Agnew details the origins of his planned Arctic expedition to find evidence of an oceanic depression or opening into the Earth. The project was originally led by Stephen Curry before his passing, at which point Agnew took over leadership. Financial setbacks during the 2008 economic crash delayed the plan to rent a Russian icebreaker, leading the team to produce a pilot film for Japanese television instead.

The history of hollow earth science is traced back to Edmund Halley’s 1692 model featuring seven concentric spheres. Halley developed this theory after conducting magnetic compass studies in the North Atlantic and observing that the magnetic poles did not align with the geographic axis. The segment also notes Halley's role in funding Isaac Newton and his famous prediction regarding the return of Halley's Comet.

The segment details specific geographic anomalies in the Arctic Ocean, including a deep basin between Franz Josef Island and Kamchatka. Osman describes underwater riverbeds at depths of 13,200 feet that suggest either a lack of water in the past or unique freshwater-saltwater interactions. He speculates that a hole at the bottom of this basin could be a point where water is exchanged with the Earth's interior.

Agnew outlines the logistical difficulties of a planned scientific expedition to the North Pole to take sea floor samples at depths of 4,400 meters. Despite assembling a multidisciplinary team from institutions like MIT and Cambridge, the 2008 economic crash halted funding. He announces an upcoming multi-part documentary series on the History Channel intended to generate interest and funding to rent a decommissioned icebreaker for the voyage.

Early Arctic explorers frequently became lost because they were unaware that the Earth's curvature slopes inward toward the poles, creating a basin effect. This inward grade caused significant errors in sextant calculations, leading to impossible speed claims in the logbooks of explorers like Dr. Cook.

Norwegian explorer Fridtjof Nansen reported finding mammals like wolves and hares in the middle of the frozen Arctic Ocean, where no food chain should exist. Nansen also documented extreme heat anomalies near the pole, claiming he had to seek shade in April to avoid being scorched by the sun.

The "clathrate gun" hypothesis involves the release of methane hydrates from the Arctic Ocean, a gas over 100 times more powerful than CO2 in the short term. NASA's CARVE project documented methane plumes 150 kilometers wide in 2013, indicating the process has accelerated since 2007. Analysis by Sam Karana suggests this feedback loop could lead to a 4-degree Celsius temperature increase by 2030, a level humans have never survived.
