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.

Not quite. The universe begins with a (mostly) homogeneous soup of sub-atomic particles that are far too hot and have far too much energy to be able to form stable atoms, not even simple ones like hydrogen -- they'd get blasted apart again just as fast as they formed. It takes some expanding and cooling until heat/energy levels drop low enough for electrons to start orbiting protons and form atoms. (Not even protons could exist in the extremely early universe -- fundamental quantum particles coming together to form protons, neutrons, and others would have been quite the development just a bit earlier in expansion.)
And they did. This isn't just speculation, we can actually see it!
The sound waves in this very early universe (called baryon acoustic oscillations) went on to develop into the high and low density parts of the universe. They effectively 'froze' in place once the gas became too sparse to carry sound waves, and the pressure waves that were left at that moment formed regions of high and low pressure, high and low density. High density areas formed more stars and more galaxies (and attracted more dark matter) than low density areas. The sound waves in the early universe are actually what created the large-scale structure of the universe as we know it today.
And that's not just hypothetical speculation. These wave patterns have been detected and have been known for decades. Yes, the early gas-filled universe was very loud -- and we can still see that today!
Epic
Well that's pretty amazing
