A tesseract (a four-dimensional cube) and the “shadow” it casts on a plane—the quasicrystal discovered by Shechtman. According to Prof. Bartal, “The fact that a quasicrystal is a ‘shadow’ of a periodic crystal in a higher dimension is not new in itself. What we discovered is that the projection includes not only the structure but also topological properties such as vortices.” Credit: Florian Sterl, Sterltech Optics

Never have I felt so far out of my depth in reading something 😂
Why would this be considerd impossible. Surprising? Maybe.But we’ve know for decades that simple holograms can store extra information encoded into wave front interference patterns. That sounds like what is happening here, at least in principle.
I’ve always thought that all of this “4D” is just nonsense.
I need someone to correct me here. If we imagine the border from 3D to 4D is as magical as the border between 2D and 3D and essentially mean someone can move around, and through, our reality.
A 2D person will never ever EVER be able to imagine anything 3D since they lack that third dimention. The same should be true for a 3D person never EVER being able to imagine anything 3D since they lack the fourth dimention.
And now to my point. Doesn’t this make every single imagined 4D shape irrelevant. If we can see the shape, even if we cant create it, we dont lack that particular dimension no?
How do we **know** that a 4D cube is just a “wonky 3D cube with scaffolding attached”?
This might just be me being dumb here but…
I love the name of the referenced paper: “Four-dimensional conserved topological charge vectors in plasmonic quasicrystals.”
If you’d told me it was a line ftom Star Trek where they’re figuring out how to do [impossible thing] by inverting the polarized tachyon field polarity or something, I’d believe you.
