I just came back to the idea that the whole world is just a simulation on a nice super-computer like in the old science fiction film “Die Welt am Draht” from Fassbinder oder in the film “the 13th Floor”.
All that we see or seem
Is but a dream within a dream.
There is always the problem how to hide from the simulated entities that their world is quite limited. I believe in our world they found a nice solution to this problem, they made it round! 😉
