Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it.
Meaning
In A Brief History of Time, Hawking explained that no amount of experiments can prove a theory permanently, while a single contrary result can disprove it. Carry that into daily life by holding your own opinions as working hypotheses and updating them when better evidence arrives.
