Invert your image, rock on outside, spiral ramp in the inside of the pyramid, which is filled with dirt as they go.  Each level, the make a pile of dirt, stack rocks on the outside for a level or two, and continue, with the dirt walk at a shallow angle, such as 2 "courses" per "lap" around the inside, while leaving a few open on one "edge" to get the dirt in.   The rocks could be pulled up that gentle incline on rollers, or pulled up, dragging on the points of the rocks below, either way is an option.

No ramp to remove when done, simply fill it in and block in the entry "slot", fill the ramp that they built as it is going to rest at same angle as pyramid walls, a couple degrees wider, but the stones are already there.  Do a lower course, ladders and buckets, or pulling ropes of crushed limestone "up" to dump on the inside.

Once complete, there is no "ramp to remove".   They could have even been placing the capstones on during that time, as climbing them later to polish would be a bitch.   Those could also been of a much lighter and softer rock, easy to polish, something from chalk or talc family that is pretty rigid for weight.

Why I was saying that could be the reason for the specific same size of rocks for most of the work, is that was the length they needed to drag across 2 "point bearings" up the side, no matter where in the lift, some part of the outside would be touching 2 edges of the stones already laid, making it as simple as rolling them along dirt with rollers, 2 points/edges would be a lot easier than pushing it up a shallow spiral with rollers.   Either one would work.  Placing stones perfectly aligned would be a lot easier if the builders had 3 axis they could bump rock around in. (without pushing it over edge, obliviously, so 2.5 dimensions).  Maybe 2 or 3 layers of interlocking courses of rock toward the inside, to lock each of 3 axis when working together (like a brick wall locking 2 dimensions, another course and a lot of weight to lock 3rd).

Summary of what I'm saying is this:  They're made out of dirt, excespt for chambers and some passages which were extended as they moved higher in construction to ensure passages were stable andwouldn't move once dirt was placed atop.  All around the stones seen from the inside, is dirt, 2-3 layers of stone on the walls in all directions, then dirt, until the next passage.  It would explain the rock placement in King's Chamber Much easier to understand and see, if it were built in the open, from bottom up, with guys in the chamber shouting up orders for measurement changes or what they want for lunch, etc.  i.e.  communication from inside to outside so the builders can continue the desired passages to point at the right stars, etc.   They'd be excellent speaking tubes while under construction to show "no, no, you idiot, you bent it, move rock back to sunward (or whatever words they used back then, of course).

I can maybe CAD my idea if I can't find a photo or painting of what I'm thinking.  Ramp NOT outside the walls at all, started with dumping dirt out after digging out passages beneath, then preserving passages by interlocking blocks (lots of that from woodworking to large steel/concrete constructions, etc. How to they route the water lines/chimney's correctly upward building the Empire State Building?

Otherwise, similar to other spiral ramp theories, just no ramp to remove when finished, that's not efficient without the power tools/buckets/ bulldozers we have today.

Like this, but slope would have been "Top" of pyramid under constructions, inside the wall by 2-3-stone lengths, very slower spiral from 1-4courses per lap depending, made from dirt, nothing existed above them until they got that high, and they kept visuals on all the other passage exits.   Inner courses could have been uglier blocks, but if they had that copper grinding saw for limestone where setup was for one size block with smooth edges in each spot at a time (MANY Spots in quarry running separate).

Angle of sides:  51.3°   Odd the Egyptians and Romans chose that exact same angle to pile together!  

(making me think that's the reason that angle was used on pyramids ,inside - out with extra features)

That is an expended Holy Hand Grenade!  I'd need a bigger photo to decide origin's, but Antioch is not off the options.

Something, yes.  I'm guessing easier to move and fast to fill, any type of gravel, etc.    I just call it dirt for shorthand.  "Not Square perfectly finished blocks", or maybe they are, just smaller ones, but that's how I'd do it with their assumed tech level.

No outside ramp, and that's how I can think thye'd get all the channels/tunnels perfect

Thanks!

Cycles man..  Cycles.

Who wrote the book?  .gov or a  non-gov author?  Wondering why classified and shortened?  Why didn't I see this before? (  likely because I never spent time focused on these things, only engineering/ancient/past/lost ways of making/creating/building, etc.  Not a "big picture" of pre-history, I can't even get a reliable picture of our current history today.

I  agree that the Egyptians didn't build the Pyramids.  They only used clay to try and preserve the walls and the Sphinx.   That much information, from a project that lasted 20-200 years (opinions vary), couldn't have simply vanished without  An Event.  The new buildings being inferior, the patches in walls being nowhere near the precision and quality of the existing walls, had to be several centuries between them, or lots more.

As to the other topic on "the Ramps Did it!", it was meant as a conceptual outline putting together several ideas, as well as I'd go about building it most efficiently.   That's the only thing I can come up with for the exact spacing and angled pieces above King's Chamber, as well as other large rocks fitted perfectly on the sides, or even in the middle.   Solution covers altitude, shallow ramps with long curves.  No major feature directly above a different feature, Working it from bottom up, is only way I can come up with.

How to get up there, using the ramps, they had plenty of room for shallow ramps which could have been filled in partially for a section, and a new section made (I'd have to draw that, and I suck at CAD, no way I can do a CAD Animation like people expect today since theyre used to seeing them.   People need to re-grow imaginations, read book instead of video summaries, etc.   I simply cannot see anybody building an external ramp only to have to tear it down at the end.  That's a modern way as we have self-supporting steel frameworks to get altitude, which is relatively little work to remove when finished.

This may be purely bullshit with a pretty cover, without the cover, it's just an idea, hasn't moved to a theory unless there's some input from others.   Sort of reminds me of another thread, where people can't hold more than one theory in mind at once, because if they have one, all the others must be wrong.   Start playing with theories on useless stuff, like starting from scratch on survival in alpine territory.  Then read a few different pieces saying what you need to survive in Alpine conditions from survival experts then some from people actually rescued in Alpine conditions.   The equipment, wish lists, and methods are slightly different in most cases for things outside 'the basics'.  Beginning conditions of getting stuck in Alpine conditions are varied, that doesn't mean any of the methods used that worked are "bad".

If you're an expert on alpine survival, disregard.  The whole idea is to think about random things you have no emotional attachment to as far as good/bad, right/wrong.  Play with the ideas.  Read only data, not existing theories  (sometimes prefixed with "conspiracy').  Come up with your own, then read (or, sigh, watcha  videoif you must while learning), and keep modifying your idea.  Example - How many people wanted to go the Pacific Ocean prior to Lewis and Clark?  How would you do it?

The core is crushed limestone/easier to carry tings, smaller stones/etc.  The rocks on the outside are long enough to be pulled straight up the sides using the existing points of stone courses as bearings to pull straight up the side, pulled with stone and a few people on the inside through a bunch of rope/pulley type contratption.   Not take the long way the builders take filling the inside, with lighter indidual loads.   If they had an advanced enough pulley system, or, alien technology (of course), it could have been done in as little as 80 years.

I'm attacking the assumption the enitre core of the Pyramids is perfectly cut and fitted, large stone blocks.    The outside stones are just a decoration for a pile of .. something, in the center, with the enclosures built on the way up.  That method would allow precise positioning and lining of tunnels/tubes/galleries at any angle, lined with stone, as well.

I jus  tossed out as an idea, has little input on those in the Orient, a few of the South American pyramids are most certainly dirt with stone facade, etc.    If groups went worldwide post pyramid, they'd likely use similar methods to build them elsewhere, or simply the knowledge any why they need to be built elsewhere around the world.  Half the others have a step in the sides as well as a smaller human staircase up the side.  etc.

Lots of assumptions made, it doesn't answer all the questions, but with a ramp 20 to 50' wide on the inside, or even multiples, there's still plenty of room to go around corners, until nearing the top, when the number of stones reduces inversely square to the height and construction goes much faster, needing fewer blocks.

--ETA:  Analogy:  Have you ever slid a washer/dryer up/down basement stairs resting on the stair points alone?  Maybe with a handcart having a belt to span the points of stairs as not to mar stairs or appliance?  Same theory.  point/knife bearings work pretty well.

I was going to say "Those are too heavy on the tinfoil for me"... Then I watched them and realized I'd come up with similar observations.  Not the same, bt in a sequence of events/how'd this happen search on many thinks.  Generally not geology or socio-economical things, though.   Mostly Old Testament and Older or changes which were supposed to occur very slowly happening in 50 years (where I danced with Geology a bit).  I'm more of a "Scientific Philosopher" just trying to keep up.  Today, everything is so specialized, I stick with mostly overview, unless I already have big chunks of other already known, as in the Math/science blocks to make a big picture between several, and don't need to actually calculate statistics of historical water conditions to decide what type of concrete put in driveway.
