But tesseract is in 3-dimensional space.

A tesseract is a 3 dimensional representation of a 4 dimensional body. The fact that a tesseract has to be animated to show all of its 4 dimensional vertices in 3 dimension is an act of shaming 3 dimensional space for being “less than”. Frankly, I don’t stand for this type of body shaming.

Technically speaking, all images are 2d projections

YOUR MOMS BRA SIZE IS A 2D PROJECTION

Well yeah, that’s how it fits on the tag.

And this is a 2d image of a 3d projection of a basic 4d shape that we literally cannot comprehend

It’s not. The walls shown here are impossible, get clipped, but the shape itself is 3D.

Don’t know what you are talking about. I can perfectly comprehend it, it’s a gif with moving colours.

We’ve never seen anything 2 dimensional. Everything we can see has some form of all 3 dimensions in it. Even shadows are 3 dimensional. We conceptualize them as 2 dimensional on a wall, but they have depth. (Think of how when you see a line it’s actually 2 dimensional due to the width of the line, then apply that concept to depth as well)

A shadow is not the same as a line drawn by a pencil. And a 2d line can be for example the contrast of two colours, the “line” that delimits an object from your perspective - these are no drawn lines with any width, they are not there as full 3d objects. I would think a shadow is a similar case, just as a film projection. It has no thickness.

Well shadows are the absence of light, so defining them is a little weird, but they exist the entire distance from where the light source is interrupted to where they are projected on, same with projections, it’s not just what’s on the screen, but the light the whole way to the screen.
Even ignoring that, the surface that a projection lands on has texture and depth.

Two dimensional projections can be represented in three dimensional space. Even single dimensional entities are welcome here.

If you look at a sheet of paper on edge, you can see a poor man’s representation of one dimension, while hiding an additional dimension, made in the only way you can actually have a thing to hold with yet one more
