Whether or not this particular science methods and findings are valid, they did drill 2 holes - one in front of the Sphinx and another by one of the temples nearby or at the Great pyramid and found rose quartz which geologically should not be there [ the plateau is made up of limestone and sandstone - there is no granite there ]. Rose quartz was used to create structural supports. Bothe holes wete sealed without comment.
Hawass’ replacement seems even more close-minded. When they allow modern stone dating techniques to be used - then there will be a change. the only one I know about was on the Pyramid of Menkaure [ supposedly the newest one of the three ] and the single sample was found to be 350 years older then the conventional date. After that all dating had to be done in Egypt - which does not have nor can afford the very expensive equipment to do stone dating [ optically stimulated thermoluminescence ]
Could that.. even be possible?
The sense I get it that the Establishment is the biggest sealed tomb of them all.
