It sure would explain the similarity between the ever more potential state of America and her novel The Handmaid's Tale.

I think time travel is possible, but you can only change things from the perspective of the person who travelled back. The original timeline just keeps on going.

Person (a) travels back in time to kill Hitler and succeeds. That new timeline exists now without Hitler, but in the original timeline is already written in stone. There is no changing it. The moment that person travels back, they've created a new timeline. It's both impossible for them to change the original timeline, and impossible to ever return to the original timeline because if they go back to the future they'll only be travelling along the new timeline.

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.
