# Thread: Two dimensional planes only exist in the mind.

1. Here's my rationale on the matter: the mind is deceived by the eyes. A sheet of paper has 3 dimensions, yet in our minds the surface upon which we doodle is regarded as 2 dimensional. That is merely deceit for lead and ink are 3 dimensional and do not magically become 2 dimensional upon the surface that they adhere to. The eyes are deceiving the mind for what we can't see is excluded from being relavent and the afore stated facts aren't being considered. What is unseen is the side of the lead that adheres to the page which is opposite to the side that light exposes to the eyes. The distance between the two sides is the measure of its 3rd dimension as is the case with a sheet of paper. If what I have stated as truth is just that then this brings into question all perceived dimensions beyond a 3rd (ie if reasoning rooted in the existance of 2 dimensional things is the sole bases upon which other dimensions beyond 3 are thought to exist).

3. We live in a physical 4 dimensional space-time universe. Mathematical constructs have no such limitation. What's new?

4. If I take paper and stack it with some other papers, is the space between the sheets 2D? I know that this space would have a length & width but where did the depth go? Thinking I have made a mistake but where? Does an actual space exist between objects that are touching?

Are they limited in that their start off point is rooted in the physical world.?
I rationalize these "unphysical" dimensions as "limits" even if we are unaware of them.

We operate under a misunderstanding that nevertheless works as a model.

"Objects touching" is a question in itself.

To my knowledge it is fields that interact ....

looking at it at the molecular level, there is plenty of space between the sheets.

8. Guess whose coming to dinner! Alright the thread I started needs to die. I didn't understanding that the whole thing is a mathematical construct. Now that I do I label this thread worthy of the death penalty for the crime of ignorance.
