If we do the analogy with CPU, then plank time is CPU clock, and plank length the discretisation of field, a bit like floating point precision. At each clock, causality influence the cell next to her.
But in this case, why the universe so huge and why speed of light so slow ?
I mean, speed of light is fucking slow compared to universe, but quite instantaneous at our scale. It seems like the simulation has been designed to work well at our scale. So, are we the subject of the simulation, or an unexpected side effect ?
Holy fucking shit ! I just fall into this rabbit hole, I was suppose to mow the lawn and go to the dump this morning, my wife will kill me ๐
