#2I am very curious as to what else they find through these excavations

#3Anyone have a better idea how this process works?

#4I wonder how they get permission to scour Egypt with a satellite camera. And even if permission was given, will Egyptian authorities allow control of the satellite and the images captured to remain with a university outside the country? Anyone have a better idea how this process works?

#6History repeats itself. I wonder what we can find in our past that will inform our future.
(although, one might say, the main thing that one learns from the study of history is that people do not learn from history)

#7No word on whether Goa'uld holding chambers have been found in the new pyramids, I guess. History repeats itself. I wonder what we can find in our past that will inform our future.

#8>"These are just the sites [close to] the surface. There are many thousands of additional sites that the Nile has covered over with silt. This is just the beginning of this kind of work." I am very curious as to what else they find through these excavations

#9How can you see a mud brick under sand because it is "much denser than the soil that surrounds it"?

#10How does this work exactly? The wikipedia page on Infrared did not turn up any such use... or I missed it. How can you see a mud brick under sand because it is " much denser than the soil that surrounds it "?
This is detectable in the light that is reflected back.
It's not dissimilar to how an ultrasound scanner is used to look at a baby in the womb. In fact, ultrasound is used in archaeology as well to do this sort of stuff, obviously on a smaller scale.
This is the wikipedia page you want: http://en.wikipedia.org/wiki/Infrared_spectroscopy
Although that page discusses things at very different scales to what we're talking about here, (while I am not a physicist,) the principles are basically the same.
