You create a theory. Prove the theory to be true by testing it. If it works, it is true. If it does not work, it is not true.
What do you mean prove that they are true? There's no true or false - they are simply there in the sky, imaginary figures.
Prove that if it were true then there must be a contradiction.
you can't, but you can't prove a negative either.
To prove a statement false, you need ONE example of when it is not true.To prove it true, you need to show it is ALWAYS true.
if it's true
It is rare and difficult to prove a hypothesis true or false through experimentation. While it is typically easy to prove something completely false, proving it true is another story.
Logic has no limitations beyond that of the language used to communicate the idea. Logic cannot be used to prove things that are not true, but that is inherent in that to prove something it must be true. Pure logical reasoning has little application because there is not enough data to further it to any specific action. Abstract reasoning has infinite application.

true
It is impossible to prove a hypothesis true because science aims to falsify hypotheses rather than prove them true. A hypothesis can only be supported by evidence, but it can never be proven definitively true because new evidence could potentially challenge or change our interpretation of it.
