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:

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
  4. Posts must be original/unique
  5. 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.

We can traverse space because it's space. Everything in the universe can traverse space. Similarly, the entire universe experiences time in only one direction. Time and space are the same thing. The movie Arrival is fiction and has nothing to do with the physics here

Space and time are not the same thing, they are facets of spacetime. We are only able to traverse space because we can properly perceive it, we do not have the ability to traverse time. I obviously understand the movie is fiction, it's still a decent attempt at showing what it might be like to be able to truly perceive and traverse time. Our way to understand it (as depicted in Arrival) is the ability to actually see and experience the past and the future. You and I and no being we know about has the ability to see anything except the present.

As an example, the screen you are reading this on presents a 2d image. It does not have the ability to produce a 3d image (though we can make illusions that seem like it sometimes). That screen is constantly moving through 3d space (on spaceship Earth), but you still wouldn't say that it's presenting a 3d image because it doesn't have the ability to directly interact with that space. Just like how we are moving through time but don't have the ability to directly interact with that spacetime.
