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
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Posts must be original/unique
- Be good to others - no bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia
- Adhere to Lemmy's Code of Conduct

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
