Houdin's theory is just that - a theory. And I don't think Wheddon's counter arguments hold any water. For one thing, he misstated or misquoted Houdin's ideas/theories several times. Ergo his debunking ability is wanting. He said that "Houdin has purported a theory that claims a spiral ramp could have been used in moving the blocks up the side of the Great Pyramid." that's not accurate. Houdin said the spriral ramp was inside the pyramid, not up the side. Also, how does Wheddon account for the spiraling found in the "x-raying" of the pyramid. And once the level of the pyramid rose higher over the internal ramp, the ramp's ceiling would likely be cambered to support the weight above, as in the Grand Gallery. So, as a failed engineer, I still think Houdin is still plausibly right. Would be interesting to see if & when they can go back to the pyramid & try & prove the theory. Besides, I have built plenty of Legos to know what's possible & what's not.
