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
- Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct

A white dwarf is a remnant of a dead star. It cannot go supernova by itself.
It can, if it's stealing matter from a companion star and it crosses a critical mass threshold (around 1.44 solar masses). Look up "type Ia supernova"
Which means it does need outside help (even passive help).
