Falsifiability
Falsifiability is an important idea in science.
A scientific claim is falsifiable if there is some possible observation or experiment that could show the claim to be wrong.
Why It Matters
Science works by testing ideas against evidence.
A useful scientific claim should make predictions that can be checked.
If evidence repeatedly conflicts with the prediction, the claim may need to be changed or rejected.
Example
A claim such as:
“Every sample of this isotope has the same measurable half-life under the stated conditions”
can be tested using measurements.
Falsifiable Does Not Mean False
A falsifiable idea is not automatically incorrect.
It means the idea can be tested in a meaningful way.
Nuclear Physics Connection
Ideas about radiation, decay and nuclear behaviour are supported through experimental evidence and measurable predictions.

Common Mistakes
- Mistake
Falsifiable ≠ false.
- Mistake
Science does not prove every theory with absolute certainty forever; models remain open to new evidence.
