It at first reading might seem that a hypothesis must be proven wrong.
Yes, that is the common misunderstanding of the falsifiable principle. The real idea is, if a hypothesis is scientific one, there must be a test that will prove it false, if it is false. The test then being made, will fail (to prove it false) and therefore, prove it correct. The falsifiable principle does not require the test to actually be made, only that such a test be possible. If no such test is possible, the hypothesis cannot be a genuine scientific one.
“There are fairies at the bottom of the garden” is not a legitimate scientific hypothesis, because there is no way to disprove it. “Deuterium hydroxide is heavier than water because of extra neutrons” is a disprovable hypothesis and therefore a legitimate scientific one. Experiments to disprove it will fail.”
This does not mean that conjectures about other doubtful things are not legitimate, only that they are not “science.” There is more to knowledge and experience than science, however.
