Explora Books to Feature Ruth Leedy Carr’s Alternative Earth Model, Tipping Point for a Hollow Earth, at London Book Fair

While the scientific community remains largely silent on the stability of our planet’s rotation, a provocative new study is heading to the London Book Fair this March 10–12, 2026. Visitors to the Olympia London in Hammersmith will find Explora Books showcasing a title that challenges the standard model of our planet: Tipping Point for a Hollow Earth: How Asimov and Sagan Backed My Prophecy of a Polar Hole Shift to Europe by Ruth Leedy Carr.

Vancouver, British Columbia, Canada, 7th Mar 2026 – Most people look to the stars when they think of space exploration, but Carr suggests we should be looking beneath our feet. Her work investigates a looming axis shift—a geological event she argues is the most urgent issue of our age, despite being ignored by mainstream media. By connecting the dots between planetary physics and the internal structures of celestial bodies, Carr presents a case for a hollow Earth that is as unsettling as it is meticulously researched.

The book doesn’t just rely on theory; it brings heavy hitters into the fold. Carr explores how literary and scientific icons Isaac Asimov and Carl Sagan left behind a trail of clues that support her findings. By analyzing their writings and riddles, she suggests these thinkers provided a map for a future the public isn’t being prepared for.

One of the most striking elements of the book—and a certain conversation starter at the London Book Fair—is the evidence regarding Mars. Carr points to images of a lighted polar hole on the night side of the Red Planet, allegedly powered by an internal sun. The book details the strange silence from NASA when questioned about these lights, raising a sharp question: why is this data being kept in the dark?

Rather than a dry academic text, Tipping Point for a Hollow Earth functions like an interactive investigation. It uses diagrams, historical legends, and even Arthurian myths to show how the “hollow Earth” idea has been hidden in plain sight for centuries. Carr, who was once named the world’s leading proponent of this theory by researcher William L. Moore, brings her background in journalism and psychology to ensure every claim is backed by a careful examination of facts.

Attendees at the London Book Fair will have the chance to see why this book has become relevant for those who distrust the official narrative. It is a work for the curious—those who suspect that the Earth’s rotation is more fragile than we are told and that the “tipping point” is closer than it appears.

Tipping Point for a Hollow Earth: How Asimov and Sagan Backed My Prophecy of a Polar Hole Shift to Europe is available on Amazon and other major retailers.
