Yeah, I figured it was impractical since the image in my head was some giant space laser from the ISS scanning Egypt

Thank you for explaining though!

I'm going to sound really dumb here, but can't they do some sort of sonar locating of tombs? Like man there sure is a giant hole 5 ft under the surface over there maybe we should see what's in it?

Isn't this how stud finders work? Like finding the less dense areas?

This feels like a representation of anxiety
