How does science work?
Science isn’t about ‘truth.’ It’s about what has worked so far.
- No hypothesis can be proven to be true. It can only be shown to be false. (A hypothesis must be falsifiable.)
- A complete hypothesis must work at all places and times.
- Only one bad prediction is required to falsify a hypothesis.
Example: Newton’s Theory of Universal Gravitation
- superceded by Einstein’s Theory of General Relativity
- still a useful approximation for most situations despite having been falsified.
