Did Charles Hapgood and Einstein Really Support Crustal Shift Theory?

The file

This article draws on the episode above.

Charles Hapgood crust theory gets overstated fast: the episode says Albert Einstein did support Hapgood enough to write forewords, but not in a way that turns every crust-shift claim into settled science.

Charles Hapgood published The Earth’s Shifting Crust in 1958, and the episode treats that book as a real stepping stone toward Chan Thomas rather than as proof that Hapgood and Einstein shared one fixed theory forever (1:41). The same discussion adds a detail people often skip: Einstein wrote the forewords for two of Hapgood’s books, yet Hapgood later revised part of his own model after working with scientists including Einstein (2:02).

Did Einstein actually back Charles Hapgood’s crust theory?

Einstein did back Charles Hapgood enough to lend his name to Hapgood’s work, but the episode does not present that as a blank check for every version of the theory. The important fact it gives is narrow and specific: Einstein wrote the forewords for two Hapgood books, which shows interest and encouragement, not unlimited approval of every claim later tied to Hapgood.

The article’s key distinction sits there. People often treat Einstein’s involvement like a final verdict, as if a foreword means complete scientific signoff. The episode does not frame it that way. It uses Einstein’s connection to show that Hapgood was taken seriously enough to be engaged, while also saying Hapgood changed his own thinking later.

That matters because the popular retelling tends to flatten the story. Once Einstein’s name enters the picture, the theory gets repeated as if both men stood behind one simple idea: ice builds up, the planet tips, catastrophe follows. The episode says the record is messier than that. Hapgood’s early book argued that the ice caps could knock Earth off axis, but later he said he had gotten that part wrong after discussions with scientists that included Einstein.

So if you came looking for a yes-or-no answer, the episode gives you a two-part one. Yes, Einstein supported Hapgood enough to write those forewords. No, the episode does not treat that as Einstein endorsing every later popularized claim about sudden global crust shifts.

What did Charles Hapgood actually claim, and what did he change?

Charles Hapgood argued in his early work that a major pole shift had happened in the distant past, then later revised the mechanism behind it. The episode places his first big claim around 9600 BC, or 11,600 years ago, and says he connected a shift of between 15 and 40 degrees to the idea that Antarctica may once have been less heavily covered in ice.

That is the version the episode treats as the bridge to Chan Thomas. Hapgood’s early argument gave Thomas a framework for thinking in terms of dramatic planetary displacement and catastrophe. But the episode makes a point of separating Hapgood’s original mechanism from what he later accepted. Thomas, in the episode’s telling, seems to draw on Hapgood’s first-book idea that the ice caps themselves could throw Earth off balance. Hapgood later pulled back from that.

The change shows up in the way the episode contrasts The Earth’s Shifting Crust with Hapgood’s later book The Path of the Pole. It presents the later work as an update, not a victory lap. The key nuance is that Hapgood did not simply repeat the first theory unchanged. He revised elements of it, and the episode ties that revision directly to his work with scientists including Einstein.

If you only hear the headline version, you miss the most useful part. Hapgood matters in the story because he influenced later catastrophe theories, but he also complicates them by revising his own earlier explanation.

How does the episode separate Hapgood’s idea from accepted plate tectonics?

The episode separates Charles Hapgood crust theory from accepted geology by treating slow continental drift as a different process from sudden crustal displacement. It says continents have drifted and collided for almost 4 billion years, and it names Gondwana as a landmass that existed for 400 million years (2:09) (2:19).

Those two deep-time markers do a lot of work. They place accepted plate movement on a scale so large that it should not be confused with the abrupt, civilization-shaking shift described in Hapgood’s earlier model. In other words, the episode does not fold mainstream geology into Hapgood’s proposal. It keeps them apart.

That separation also sharpens the point about influence. Hapgood is presented as a precursor to Chan Thomas because both deal in rapid, dramatic planetary change. Plate tectonics sits in the same broad conversation about moving continents, but the episode treats it as a separate, accepted process with a very different tempo and framework.

If you are trying to understand what Einstein’s forewords do and do not prove, that difference is the part to keep. The episode uses Hapgood to show where Thomas likely got one line of thinking, then immediately adds that Hapgood himself revised the ice-cap mechanism instead of standing by it unchanged.
