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)
This text or drawing is not really 2D. Down at the atomic/molecular level they are still 3D particles. We are just abstracting it as 2D.
The text on your screen doesn’t exist as molecules. The text exists as the light travelling between your screen and your eyeballs.
The length light has to travel to reach your eyes is three dimensionak, but the actual shape of the text is still two dimensional.
Then there is the light itself, which has wave-particle duality; a light particle has no discernable border, and can be described as a one dimensional point in space, with a two-dimensional wave function.
