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.

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.

A claim such as: “Every sample of this isotope has the same measurable half-life under the stated conditions” can be tested using measurements.

A falsifiable idea is not automatically incorrect. It means the idea can be tested in a meaningful way.

Ideas about radiation, decay and nuclear behaviour are supported through experimental evidence and measurable predictions.
