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 best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

As far as I know (I'm not a physicist), it's not all that clear that gravity is caused by a particle. It makes sense to assume it is, because of parallelisms with the other fundamental interactions, all of which (other than gravity) are caused by particles that have been thoroughly observed and studied.

So we kinda know what a graviton would be like and what to look for, but so far it hasn't been found, and its existence hasn't been conclusively determined. There are some alternative hypotheses that in fact gravitons don't exist at all, and gravity is just a consequence of the shape of space-time, which I think is what's going on with black holes.
