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.

I think it would depend on how the shapes extend into the 4th dimension.

Where the 2D slice is two circles: if in 3D we have a sphere inside a sphere the inside is occluded, but if we have a ball inside a cylinder the inside is visible from two ends.

Likewise where the 3D objects are a ball inside a ball, they may be two 4D spheres or one might be more like a cylinder.
