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
- 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
- Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct-----

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?
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.
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.
