1D and 2D are just mathematical abstractions. Everything is just 3D and that’s it. There is no time, just space with a state.
(I tried to explain better in comments so please check that. I would be glad if someone could give me a response to this brain fuck I’m having)
A “dimension” is just something that can be measured. Imagine you have a square of paper and it has 5 coins on it. It has a width, a height, a thickness, a coin count. That’s 4 dimensions already. It also has zero elephants on it, now we have 5 dimensions!
The trick is to only consider the “dimensions” you’re actually interested in.
