    If I were a 4d being for a day, I would rotate my enemies in 3d space until they’re exactly where they started but a mirrored version of themselves, so it appears to them as if I’ve mirrored their entire existence.

    They would slowly die of malnutrition as the chiral molecules in their diet (such as glucose) would no longer meet the requirements of their body

      It’s precisely rotation through the higher dimension that cannot be undone in the lower one. So… nice thought, I think?

        “in 3d space” refers to the enemies, not the rotation. I should have been more clear

    One interesting fact about 4D creatures is that they can see you, no matter how hard you try to hide in 3D space.

    Honestly it’s pretty funny to me how people think 4d is all strange and terrifying, when in fact it’s (to the degree that it can be said to actually exist, since it’s theoretical/mathematical) pretty “simple” and just headache inducing to try to wrap your head around.

    like your mind wouldn’t shatter from being moved through 4d space, things would just look completely nonsensical and impossible, it’s no more lovecraftian than subatomic physics. It’s just Kronk saying “by all accounts, it doesn’t make sense”.

      No, being rotated in the 4th dimension and plopped back down into the third dimension would be horrible and it wouldn’t surprise me if it killed you. For one, it would absolutely feel like a Lovecraftian nightmare. Your right arm is now your left. Your heart is in a different side of your chest. The “you” you see in the mirror will be the “you” you’ve seen in photographs. But look into chirality in chemistry. Your body would suddenly have tons of molecules that are a mirror image of what they should be and work with the mirror images of molecules they used to. Everything already in you would get flipped, but you might be on a ticking clock if you aren’t able to get the chiral opposites of necessary amino acids.

        From your perspective, your body wouldn’t really change. It’s the handedness / chirality of the universe that would be flipped. It’s an odd thing to think about…

          I debated on what it would be like before I posted and I think you’re right. It would be more like being “in the mirror” sort of. Everyone would look different to you and you’d look different from what people remember. You’d need to learn to read and write in reverse.

      This projection of the 4-dimensional being into 3D space appears as the Mandelbrot set. Weirdly, it appears to be the Mandelbrot set no matter what angle you look at it from in 3D space.

        Alternatively it can just be any 3D shape depending on how thick the ‘slice’ of 4D space intersected by our 3D world is and wether the 4D thing is undergoing translation or rotation.
