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.

Maybe if you timed it juuuuuust right you could land somewhere on the planet as it orbits the sun and comes back to the same position once a decade or century or whatever? I mean I guess it depends on how you determine absolute location in the universe. Is that even possible with the universe constantly expanding?
Nope, not possible. The solar system itself is moving as is the galaxy... it's useful to think of Earth's orbit as spiraling around the sun in the direction our star is traveling. So 1 orbit later we have not come to the same location.
But moving relative to what?
Everything else.
Galactocentrism was established in 1925, which realised that our solar system is not near the center of the Milky Way. So, we are moving relative to the center of our galaxy.
In 1929, evidence was found that everything else is moving away from us. So we are moving relative to everything else.
In 1931, the Big Bang theory started superceding Galactocentrism, which was an acentrist model of the universe (where there is no center).
But what frame of reference?
Everything else. Or anything else, if you select a single quark (presuming we don't split a quark).
If everything is moving away from us, then everything is moving away from everything else.
It's just that some things are moving away from us faster than they are moving away from other things
