Showerthoughts

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 most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

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.
