The Spacetime simulation is the theory that everything is in a simulation. There are multiple layers to it.
Layer 0[]
Layer 0 of this simulation is the Universe. The universe represents a singular 1 or 0 in a byte of code. The universe is the reason that all layers above exist.
Layer 1[]
Layer 1 of this simulation is the Omniverse, which represents a singular byte of code. The omniverse is the reason that all layers above exist.
Layer 2[]
Layer 2 of this simulation is The Box, which represents a singular line of code. The box is the reason that all layers above exist.
Layer 3[]
Layer 3 of this simulation is the Uniperaverse, which represents a singular website. Said website can vary in size very drastically, such as having a singular letter on it or being the biggest website on the entire internet. The uniperaverse is the reason that layer 4 exists.
Layer 4[]
Layer 4 of this simulation is the The Drum, which represents a website with multiple website links on them, i.e wikipedia, wikia/fandom, etc. The drum is the reason that layer 5 exists.
Layer 5[]
Layer 5 of this simulation is The Never-Ending Void of Darkness and represents all websites on the internet. The never ending void of darkness is the reason that layer 6 exists.
Layer 6[]
Layer 6 of this simulation is The Hyper Flower, and represents all data on the internet. Unlike the other layers, this one doesn't really contribute to other layers, it's just the combination of all the below ones.
Layer 7[]
Layer 7 of this simulation is Existency, and represents the background of your computer. Also doesn't really contribute.
Layer 8[]
Layer 8 of this simulation is The Clockwork, which represents all the functions in the computer like turning on, turning off, alt f4, etc., and each function is a distinct clockwork. This layer is probably the most important layer and makes up the last layer.
Layer 9[]
Layer 9 is the final layer of this situation, and represents the spacetime simulation. This represents the computer itself and is the reason that the data exists in the first place.
