ELI5: Why haven’t we fully explored the pyramids yet?
I was watching a documentary where they were talking about a void within the great pyramid and how we don’t know what’s inside it! How come we haven’t we been in and had a nose around?
Not sure how old the program was OP watched but they found one void in 2017 using cosmic rays. I'm guessing the pyramids are way too solid for ultrasound or x-ray to work.
The base has a length of 230 meters on each side and the largest interior chamber measures roughly 10 x 5 x 6 meters so yeah, loads of dense solid stone there.
