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.

That is the question, what banged and why did it bang. There's some quantum theories that elude to a possible source of the big bang, but nothing widely accepted. As to why, that's an even tougher question.

The term singularity as applied in cosmology comes from the mathematical definition where one variable approaches infinity as another goes to zero. This is bad in math since it means an equation is not defined across all values. This is what happens mathematically as you get closer to time zero for the big bang. Same with the gravity of a black hole as you move toward the center. In that sense the size of the big bang at time zero would be zero, but the math breaks down so it's not actually defined. Physicists generally believe that's not the case due to the quantum nature of the universe, but we don't have the math to explore it.
