Dear Frank, Your Web site section that supports the mainstream theory of pyramid construction seems out of date in light of the new polymer microanalysis and limecrete reconstruction of some of the stones at Giza in the last few months : see Casting Stones at the Pyramids <http://www.webproclaim.com/emailmarketing/lt/t_go.php?i=1295&e=MzQ1NDEz&l=h ttp://www.answersingenesis.org/docs2007/0129casting-stones.asp> and footnotes When your Web site has been updated, please notify me and the cc: address above, which is a forum interested in your response. Meanwhile here are a few of the issues that should be covered: With chemical analysis it is now possible to trace each building block right back to its original quarry, as did the Geologists H.D. und R. Klemm during the last 20 years. How did the Klemms? analysis manage to miss the air bubbles, the vertical variation in density and traces of a rapid chemical reaction which did not allow natural crystalization? ALL big pyramids were built with this method, according to Davodovits. The knowledge got lost durig the 5th dynasty (why???) The polymer chemists claim only the top stones used this process. Haven?t you ever lost anything, Frank? Maybe the answer is the same, or a consequence of our decline since the first transgression. He[Davodovits] can produce very little evidence to support his idea, Well, now he certainly can provide hard evidence ? it?s called analysis and experimentation Several of his claims can be disproven just by looking at the pyramids with the naked eye: The uniformity of the pyramid blocks The uniformity of their layering The 1/10th millimeter precision of the core blocks Why is visual inspection superior to X-rays, a plasma torch and electron microscopes? The blocks have weathered a bit in 5,000 years??.and settled ? just like concrete. Some pyramids were partially demolished by grave-robbers, which also could explain the chisel marks shown in the pictures. Where did .1 mm precision come from? If Davidovits said this, where is his proof? The reason for unequal blocks is stated in the references? seismic stability. New and old blocks at Khufu's pyramid How could such irregular blocks have been formed? How casted blocks would look can be seen on the south side of the great pyramid. There Vyse blasted a gap into the face of the pyramid to look for a secret entrance. To stabilize this, concrete blocks were casted. It is very easy to see the difference between the natural and later casted blocks. The regular form of the newer block on the right is clearly visible and in contrast to the original blocks on the left (with ancient mortar between them) The analysis and conclusion of the limestone concrete theory relates only to the pyramid studies at the great pyramid at Giza and concludes the pyramids are a mixture of both, with concrete types at the top; yet the photos are selected from pyramids of other places and times, about which no claim is made w/o separate and independent study. The pictures were taken of the core, when the top stones were of concrete type. The core stones were natural , as the Times coverage below states. Using photos that don?t apply is called a logical strawman ? attacking a position not taken as if it were. Another problem: If the Egyptians had used bottomless moulds, the material should have run between the gaps of the stones. A phenomenon nowhere to be seen on the pyramids, therefore the Egyptians must have had used casts with a bottom plate. But how and why were these removed? So the MS theory of cutting, transporting and lifting huge quarry stones is no problem, but removing the wood bottom from a mold is a problem? Wasn?t the simple lever covered in your physics class? The references say ? and the videos show - the limecrete is allowed to set to a soft solid in a mixing pit and then put in final position to be tamped down by compactors. A bottom wood form may not have been needed at all. Another plausible option: A flat bottom slab may have been quarried, or formed from another mold. The mold frame would then be wood on the sides, but stone on the bottom. If you think the builders weren?t smart enough to think of this, then why didn?t you think of it? Mainstream thinking is a one-track mind which crushes creative and logical imagination and praises illogical speculation. So where are the moulds??? Another problem: the material of the mould (wood, brickwall, mortar/stone) forms prints on the surface of the casted objects. But where are they? You think the wood would still be there, laying around near the pyramid after 5000 years? Sure, that?s logical !! The limestone shrinks slightly while setting, separating from the mold and leaving no mold marks - ?. As seen in the video. ?prepared but not yet loosened blocks can be found in the quarry areas of Giza, like these in the southern Khafere-quarry How does this show that quarry blocks were used at the Pyramid top, when micro-analysis shows otherwise? How does the use of the quarry for the base construction disprove the use of concrete construction at the top? In fact, why can?t it be said that the incomplete cuttings in the quarry shows the Egyptians tried to use the quarry stones for the pyramid, but abandoned it as too difficult when they got near the top? For each stone about 3 tons of stone had to have been pulverized. Thin layer photos of the pyramid blocks showed no trace of compound stone, so it had to have been pulverized right down to the basic compounds - calcite cristals and micro fossils Answered in the video ? limestone from the Nile flood flats was different from the quarry stone in its consistency ? it crumbled to the touch, easily pounded into powder. Another strawman ? assuming the limestone powder source was the quarry stones. There are materials needed which are rare in Egypt. Now, maybe. The resources were used up in construction, forcing later pyramids to be of lower quality stone. Is oil as plentiful now as 50 years ago, Frank? Davidovits also has no explanation for the use of small blocks. The concept of seismic stability has been overlooked here ? not surprisingly. In your Web site bio you say your science background consists of a few physics classes after high school and you now work in IT on computer games. This is sufficient credentials for some forum members but others ? like me ? think you may be parroting what you surf superficially from the Net, disregarding whether it applies to the issue. If you accept the seismic explanation, will you give a technical explanation of the wave theory support for stability in your update? If you disagree, then you would have to, of course. If not even a SINGLE stone could have been produced with Davidovits' methods in one day, how long should the pyramid have been built on? How and where is this premise supported ? many stones could be produced in a production line process. Or are ludicrous assumptions being made, such as the builders having only one wood form? Production seemed easy enough on the video?. Ten days to produce a large block, the setting time increased by the climate difference between France and Egypt. We look forward to your update, Frank. Let us know. Dr. Robert Bennett
