  • Modern archaeologists don’t think the single giant ramp was how the pyramids were built. The ramp would have to be like 2km long to make the angle reasonable for getting blocks to the top and there is no evidence of a ramp so large.

    You also can’t use a spiraling ramp to construct the pyramids as exact as they are since you’d need to see the corners as you build them.

    Houdin posits that they used an external ramp to about 1/3 the height and then internal ramps for the remainder. This reduces the amount of material needed and keeps the corners visible.










  • They only got to 1300 feet which is well above crushing depth for remotely operated vehicles and cameras. Challenger deep is 35,000 feet and 27 people have been down there.

    I would assume the bigger problems will be visibility (cave systems tend to have murky water and it sounds like the bay also has murky water) and being able to maneuver an rov or submersible in the passages. Some caves are so narrow that cave divers have to take off their gear and squeeze themselves through a passage so getting an rov in would be impossible.
