Hello guys I am a bit struggling to put a name on the distant memory I have of some kind of science fiction novel, or maybe was it a different kind of writing ? I am not very sure but maybe you could help me.
It was about some kind of earth shaped pyramids floating in space and I remember that the thing was about developping a crazy universe with different kind of physic rules than our own.
I think that the definition of time was especially extreme.
I remember that it was posted on 4chan occasionally this is where I saw that thing.
I have made a shitty drawing of my memory so if it sound something to anybody, please tell me.
