Pyramids built from inside out?

A new theory on how the Pyramids were built:

A French architect says he has cracked a 4,500-year-old mystery surrounding Egypt's Great Pyramid, saying it was built from the inside out.

Previous theories have suggested the tomb of Pharaoh Khufu was built using either a vast frontal ramp or a ramp in a corkscrew shape around the exterior to haul up the stonework.

But flouting previous wisdom, Jean-Pierre Houdin said advanced 3D technology had shown the main ramp which was used to haul the massive stones to the apex was contained 10-15 metres beneath the outer skin, tracing a pyramid within a pyramid.
I still think it was aliens. But look at how they want to prove the theory:

Now, an international team is being assembled to probe the pyramid using radars and heat detecting cameras supplied by a French defence firm, as long as Egyptian authorities agree.
What, using high-tech defense equipment on the national treasures? I suspect Zahi would say no unless he gets to do the Discovery Channel special about it, and Hosni will say no unless he gets to keep the high-tech gadgets.
