A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)

A 3D simulation running in a 2D universe?
It's a hypothesis that our perceived ability to see things as "3D" is just a holographic effect, exactly how a 2D hologram gives rise to the illusion of a 3D object.
Not that out there, especially if you consider VR, or anything in 3d on a computer, is borne from 2D instructions.
Now I want a 5- or 6-dimensional VR game where head tracking rotates the camera in one set of dimensions while the right stick rotates it in another
My hypothesis is if you found a way to send “sensory” data about points in the 4D universe to a brain, perhaps a very young brain, that brain could develop an intuition for 4D space and motion.
Brains are incredible, I bet it might work even with an adult, it would just take some getting used to.
Another thought I had (more of a weird experiment than a game) would be to feed the view from a 3d camera into a VR headset such that you can see all of it at once. Obviously it would be weird and everyone would look funny, but I bet if you stayed in long enough your brain would get used to it and it would start to look/feel normal
Yeah. So basically physics tends to work in N dimensions, or at least that’s how he explained it. So they derived the equations of physics then added a third dimension and started a simulation. Then moved themselves into it.
In the same way, one could take a physics engine for a game, and make all those functions operate in four spatial dimensions. Then you could simulate a 4-dimensional universe.
