Tipping Point for a Hollow Earth Holds 4.4-Star Amazon Rating

Ruth Leedy Carr’s ‘Tipping Point for a Hollow Earth: How Asimov and Sagan Backed My Prophecy of a Polar Hole Shift to Europe,’ is drawing reader interest, with the title currently rated 4.4 stars on Amazon. Reviews have praised its scope and willingness to challenge established scientific ideas while acknowledging the unconventional nature of its central claims.

Vancouver, British Columbia, Canada, 10th Sep 2026 - In the book, Carr argues that an imminent shift in Earth’s axis ranks among the most urgent problems facing the planet today, describing it as a looming disaster that she says has been met with silence from NASA and the broader scientific establishment. The book also examines Carr’s theory of a hollow Mars, including images she interprets as evidence of a glowing opening near the planet’s pole, visible on its dark side. Carr, whom researcher William L. Moore reportedly described as the world’s leading proponent of the hollow Earth theory, contends that the writings of Isaac Asimov and Carl Sagan offer insights relevant to the future she foresees.

Carr draws on her background in journalism and psychology at Indiana University, along with decades of research connecting Edgar Cayce’s cataclysmic prophecies with scientific inquiry.

Rather than presenting a conventional academic argument, the book combines diagrams, historical references, and Arthurian mythology to explore the persistence of the hollow Earth theory. Reviewers have praised its readability, urgency, and fast-moving blend of scientific figures, historical references, and speculative ideas.

Reviews reflect a divide over the book’s scientific claims. Some readers have found Carr’s arguments compelling and appreciated her invitation to question established narratives, while others noted that readers seeking conventional scientific evidence may remain unconvinced. The book has also been praised for provoking curiosity and reflection, even among readers who do not accept every conclusion.

That tension between speculative argument and mainstream scientific skepticism runs throughout the reviews, particularly among those interested in alternative theories, planetary mysteries, and unconventional interpretations of scientific history.

Tipping Point for a Hollow Earth: How Asimov and Sagan Backed My Prophecy of a Polar Hole Shift to Europe is available through Amazon and other major online bookstores. For more information, visit www.ruthleedycarr.com.
