Einstein perhaps couldn't tell you one rock from another so I agree his knowledge of geology was limited in that respect. But as you say he did know physics and Hapgood's hypothesis involved some physics. Einstein eventually convinced Hapgood that there simply wasn't enough ice to do what Hapgood proposed, and I think that argument was based in physics. Hapgood eventually conceded Einstein's point and tried to come up with something other than ice to explain his idea, something under the surface. But of course that didn't really work out either.

"So if the claim is "pseudoarchaeology" as that description states, why did Albert Einstein write a foreward to Hapgood's book?"
Because he was a kind and obliging man, but he didn't know beans about geology or anything BUT mathematics and physics.
geology rocks!
Interesting. I hadn't read that Hapgood conceded that much. That's commendable (accepting that there's an error and looking for an alternate to explain a phenomena.)
As I dove down that rabbit hole, I noted that Hapgood was a PhD, but his degrees were in history (and physics, thus, wasn't directly in his path)...and that his ideas are secondhand from an electrical engineer, Hugh Auchincloss Brown. So a compelling idea promoted by people who didn't understand more than the basics of geology and physics and planetology.
Anyway... I just spent an hour of my morning falling down rabbit holes chasing that darn bunny (including a bio of Rand Flem-Ath, which had a Wikipedia link that led back to an interview with him... on ATS.) I blame YOU for that, you know! (okay...and my infernal curiosity, but, still... (grin))

That is interesting information and I will definitely check it out.
Something is still nagging at me though. There is significant land mass in the northern hemisphere far from the equator. Centrifical force should have that mass distributed around the equator yet it remains far away.
A land mass is either moving or not moving. If it's not moving, whatever forces are on it are probably largely in balance. We have small motions of plate tectonics which move the land masses maybe an inch a year, but that can be stick-slip-stick-slip at plate boundaries, and cause earthquakes during the slips.

Centrifical force should have that mass distributed around the equator yet it remains far away. That suggests to me that there is a significant force on that mass already, just not enough to move it. Which would follow to reason then, that the amount of force required to start it moving is far less than an object that would make an impact that created the moon.
This map of the tectonic plates includes arrows to show the direction of their movement. Based on this information, what can you say about the direction in which tectonic plates move?

The skill set required here is not to be an expert astrophysicist or cosmologist.

Looking at the CV's for Ben Davidson and Professor Dave, I'm not entirely certain that I'd take the word of either of them about cosmology... at least, not without a whole lot of checking with some real astrophysicists.

Talking about "classified", even that statement is bull# !
Everyone knows Ben Davidson, the charlatan lawyer that feeds the masses with doom day pr0n and children books.
He's about wrong on every statement he makes, if you do the "research"
Here is a lil video debunking Ben:

I mostly agree. As for the forces acting on a plate at any given time, there could be massive force on it, just not quite enough to get it moving. Opposing forces of equal strength = 0 force. Centrifical force must be acting on the plates. The heaviest plates will displace lighter plates when moving toward the equator, or any other direction for whatever reason. So a lighter plate moving away from the equator could still be due to centrifical force.
Pangaea was centered, by mass, on the equator but reached to both poles also.
Of course plates are more than what we see above sea level, so their distribution upon breaking apart was not visibly centered on the equator but may have been by mass.
The duration could be significantly greater if enough force were applied initially to get the whole thing started. That was my theory involving impact. Not enough to destroy everything in sight, but enough to jump start the motion and move it further than would typically be expected.
You can start by paying more attention to what's written here, and would it kill you to use a dictionary? Instead of writing all this explanation about how you're old school, you could have looked it up and found your "old school" word doesn't even exist, except as a typo in some people's minds, possibly a mispronunciation of the word centrifugal.

I like to be challenged. It makes me look further and learn more. :-)
That sort of destroys your credibility when you use a made-up word and write a comment about how you prefer your made up word instead of looking it up to find out it's not even a word. Even worse, the made up word you chose to use is at the heart of your (flawed) hypothesis. Ever hear of a "centrifuge"? It's a device which uses centrifugal forces. Not surprisingly it's related to the word "centrifugal".
There are always forces acting on the plates including centrifical. (I am old school and prefer centrifical to centrifugal.)
That's not true, and Byrd didn't say that, he said the mantle was that thick. The crust is typically a much thinner layer on top of the mantle.
As you pointed out earlier, the crust is 2,000 miles thick.
The pie is a good example. Picture that pie spinning on a table. Centrifical force is acting on it, just not enough to break it apart. Now smack it laterally from one side, hard enough to move it but not hard enough to destroy it.
If you scale down the Earth to the mass of a 1 kilogram pie, then similarly scaling down the mass of Flornce confirms what Byrd said, because something 4600 times less massive than a grain of sand is going to have a very miniscule effect on the pie's momentum when it hits.

The mantle is almost 2,000 miles thick miles thick and makes up 84% of the Earth's volume. So you're not going to push that around with anything smaller than a planetoid-sized object.

English is a living language but a language non the less. And with languages is doesn’t matter how you convey the information that is meant to be conveyed, only that you are able to convey the information. Made up word or not, if the information was conveyed it was a successful word to use.
Also yes centrifical is a word though most use centrifugal. Or maybe not. It could be just one of those write as you say errors. But air conditioning engineers use it a lot. Centrifical chillers is the term used.
Still, nothing to get hung up on and off topic by.

You use a golf ball and a grain of sand to make your point. Neither is what I am referring to. In my theory, and this I clearly stated, the object is much smaller than the one that created the moon. It is just large enough to get the mantle moving at an accelerated rate, no larger. As soon as energy is scrubbed off the mantle would return to its normal state. So no, not a grain of sand and not a golf ball. A marble perhaps, a pebble, more likely a small ball bearing.
You want to do math? Fine. Lets do some simple math. For ease of discussion lets say it takes 100# of force to make the mantle move. There is a constant 101# of force on the mantle, it is always moving. That last 1# of force results in 1 inch per year of movement. Simple. Now lets say a temporary force of an additional 15# of oblique force was added.
