Technically coral has holes in it, however, it is very dense as a material. That means that it is extremely heavy.
Here's something useful - if you pull an object on a lever, it will reduce its weight exactly 1/2. If you continue to wrap ropes around it that are mounted on a lever, it will continuesly reduce the weight by 1/2. Meaning 1/2 * 1/2 (1/4) * 1/2 (1/8) ...
It can get reduced to a stone that is easily moved as shown in the video. Notice all the ropes above the stone.
If you regard the moving stone on the front of the castle, it is just made with magnets, to my knowledge. The door was only balanced on the magnetic properties of repulsion. I don't remember that from the video, so I hope this useful. You can check it if you don't believe me.
Good thinking about the weight, however, using levers is a lesson in physics that reduces any weight to the minimal, if you want. The weight is not a problem.
Think of it this way - what did he create? Why did he create it? And how did he cut through a stone that dense? (you can check coral density online or granite density - the stones from the pyramids).
!! It is possible with human tools to cut through a dense stone, any stone, with the right tools.
I would suggest you look at the picture as a whole, rather than detail by detail. Why him? Why then? Why building a similar structure to the pyramids? And once built, what is it used for?
