The 5 platonic solids (not 4) is a failed idea that all of the universe revolves and around 5 shapes which Johannes Kepler worked on unsuccessfully until his death. His model never worked so often he decided that instead of his idea being incorrect, the entire world was wrong and the Earth revolved around the Sun.
To talk about mercury though, the first Emperor of China used a special potion called the “red lead elixir”, which comprised of mercury and the blood of young kids. It was because he was interested in living forever, but it didn’t really help him. His tomb is toxic to be around and shows signs of being filled with mercury.
Old depictions of zeppelins and flying machines exist, and most people believe that they were powered by ‘spinning mercury engines’; It’s an idea that goes back to Indian texts where palaces called vimana’s could float or fly in the air with mercury being used through spinning.
A WW2 secret nazi weapon called the “Die Glockt” was thought to have been created and inspired through the same mercury engine. Some people think it was made to float like the vimanas, and some people think that its purpose was to dilate time, and open a window to the past or future.
There is something in physics called the Alcubierre warp drive; It’s a way in which to collapse space in front of you, expanding it behind you like a moving elevator walkway / escalator. As the space in front of you collapses, making you appear to move faster without moving to the people not on the escalator, it wraps back around behind you as an escalator and appears to expand and create new track for people to walk on. Since it’s proven possible to collapse and expand space, I wouldn’t say it’s impossible to collapse and expand time either.
Too bad a miniature floating castle champion doesn’t exist in league. I would have liked to have seen a floating castle with people in it, and all of them collectively have the power of 1 champion.
