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.

Your confusion is you expect 1d and 2d universes to exist within ours, when the reality is they are separate universes.
It's not like one is built on top of the other, they most likely exist separately and incompatibly.
We currently only see models of it in our universe, just like anyone from a higher order universe would only be able to see models of ours.
It would take insane levels of technology for them to even briefly appear here, and the only reason that would be worth it is if we're essentially a "warp" zone for them where moving a short distance here would translate to a huge distance back home, at faster to whatever their equivalent of a speed of light is.
Ah that’s interesting. I didn’t think of them as separate universes.
My point still holds though. I mean, we call 3D as 3D because of 1D and 2D. Since they don’t exist in our reality (but of course they are mathematically useful). One could still argue that since it cannot(has not) be perceived since it is theoretical a.t.m, it’s not real.
May be this is some form of nihilistic thought too 🙂
No, we call it 3d because there are three physical dimensions we move thru: front/back, side to side, up and down.
We experience time linearly, so it's not included. However time behaving like the three other dimensions isn't precluded by a single law in physics. Literally everything works backwards just as fine as forwards, except consciousness. We need the cause/effect of linear time to be conscious.
Think of it like fireworks. There can be multiple in your field of view at once.
Each firework is a universe, with its own unique laws of physics and number of physical dimensions. Multiple are still "real" at the same time, even if they're incredibly unlikely to interact.
I mean, one of the leading theories on how a universe forms is there's giant "planes" randomly bumping into each other. On that scale not only are multiple universes "real" we're all completely inconsequential and incredibly fleeting. Not just as individuals, species or even planets. Entire universes don't matter.
If you're interested there's a lot to learn about with all that stuff, but it honestly doesn't really matter.
I never thought of it like that. I thought laws of physics as laws of everything. Nice thought. Thanks for response.
