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: 1

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
- If you feel strongly that you want politics back, please volunteer as a mod.
Posts must be original/unique

The next time you are trying to get one more thing into your suitcase, remember that the entire universe once fit into a pinpoint. So, it'll fit. (hobbit.world)

There is no limit to what can fit in your suitcase if you are ok with creating a singularity.

the time with a hot QGP filing every bit of space is what things would look like immediately after the Inflationary Epoch, around t=10^32. The region of space that would eventually become the visible universe was maybe the size of an orange then. Inflation is often described as the "bang" in the Big Bang. Physics can describe the universe back to inflation very well, but before that things get less clear. Most think the four fundamental forces (gravity, electromagnetism, and the strong and weak nuclear forces) were all one, at a temperature of 10^30 degrees, and things spread out and cooled until the gravity peeled off on its own. Things spread out and cooled a bit more and the strong force separated from the electroweak force. It may have been this transition that triggered cosmic inflation. Things spread out a lot more (by a factor of at least 10^26!), then stopped and returned to growing gently. That point in time is where the laws of physics are well-described, and testable in particle accelerators
