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. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

If simulation is possible, we could upgrade reality to 4D (sh.itjust.works)

If we knew how to create world simulation, and how to make it working 4D, then humans would be able to plug themselves in, and experience 4D space. Alternatively there could simulated 4D beings, whose sentience could be transferred to robot body in our real 3D space.

No. Do you have any idea how fucking difficult and complex rotations and angle math is when it becomes 3d? Quaternions, rotational matrices, imaginary numbers, gimbal lock. Things get really complicated really quick. Not every rotation related problem can even be explained and solved by modern mathematics as it is. How do you handle rotational velocity relative to a parent object so you can make a flight simulator? You can't. The "solution" to this problem is to find a different or non mathematic way to accomplish approximately the same thing.

Making things 4d would be even more ridiculous. I'd even go as far as to speculate they'll never fully figure out all the details around how to simulate 4d.
