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

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. 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.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

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 gravitons aren't affected by gravity, the same way photons aren't affected by em interactions (which they carry).

If that was the case, we would already have a quantum theory of gravity. The fact that "gravitons" (here I mean the particles of a second quantisation of GR) can interact with themselves makes the theory almost completely useless.

It's technically possible to write down such a theory, but the only way to get results out of it is to first perform an infinite number of experiments.
