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. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

Maybe we are late in the universe, perhaps universe used to be a lively and vibrant place homing millions of civilizations. Now, we stand as the last remnants, hence, possibly the most advanced. (lemmy.world)

If you have an absolutely absurd amount of negative mass, you could create an Alcubierre warp drive that won't immediately tear your ship apart. Unfortunately there's no evidence that negative mass exists, and afaik current designs use amounts that are impossible to actually use (eg. the weight of a galaxy).

Tl;dr: Yes, but they may not be possible and may still be impractical if they were possible
