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

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.

We already experience 4D; our fourth dimension is time.

It's correct, but I meant spatial dimensions.

There are some 4d experimental games. One is a space flight Sim that allows players to move in a fourth dimension, entering and exiting physical space in a semi physics-compatible way. It's really fun and it tends to break your brain a little.

What's the game?

[–] dustyData@lemmy.world 4 points 2 months ago (1 children)

Itch io has several, I can't find the name of the one I tried like 10 years ago. It was just a proof of concept, a freespace like fighter.

There's also one that turns Minecraft into 4 dimensions, or it at least cribs the aesthetic of Minecraft. I forget which. It's been a few years.

According to some physics theories, we're living in a world with at least 11 dimensions.
But we can only sense and understand 3.

[–] Daxter101@lemmy.blahaj.zone 9 points 2 months ago

Fyi, string theory, which is a popular, well known theory that assumes 11 dimensions, doesn't really have that much appeal in the scientific community. It's still fun to talk about tho

*A fourth dimension can be time.

Time is a very convenient choice for a fourth dimension, but "fourth" is purely namesake. There's no reason we couldn't describe our world in our three familiar spatial coordinates with an additional coordinate for ~~temperature~~, for example. We just don't easily conceptualize it that way because it feels less contiguous according to how we currently frame our model of reality.

Disclaimer: my sources include internet research and far too much time to think. I'm absolutely open to discussion and new ideas in whatever form.

Edit: Temperature is kind of a bad example at face value, but good conceptually. Hopefully I'm communicating my point at least we'll enough to be comprehended.
