In mathematics and theoretical physics, a no-go theorem is a theorem that shows that an idea is not possible even though it may look attractive. Like all theorems, a no-go theorem is only as good as its assumptions, including hidden implicit assumptions.
Examples of no-go theorems
- Arrow's impossibility theorem
- Bell's theorem
- Coleman-Mandula theorem
- Gödel's incompleteness theorem
- Heisenberg uncertainty principle
- Weinberg-Witten theorem
- Antidynamo theorems
