A theory or speciation can be diffulcult to prove because either the scientist does not know a part of why something happens or in some cases, like the big bang, you can not go back 14 billlions years to witness it. That means that we are not 100% sure how it happened because we had no witness and we do not the the scientific technology to re-act it.
no
yes it can prove ....
probably when you can prove it
No. Much more has to be done to prove any hypothesis a theory.
Actual research provides usable results - which will prove or disprove the theory.
In theory, yes - but it would be extremely difficult to prove an IQ of 0.
no
By performing experiments whose goal is to prove that such theory is a mistaken theory.
The same reason any other theory is accepted: it explains known observations and it makes predictions that are testable by experiment (and prove correct when tested).
prove the intersction for crisp set theory
No, of course not. Evidence does not prove evolution - it validates the theory.Evidence which Darwin had included limited fossils, and observed apparent speciation in birds.
Hypotheses are useful because they can be tested, and scientists love to test to prove if whether your theory is right or wrong.
Theories tend to Remain a Pseudo Fact, until proven otherwise, the theorist, is under no obligation to Prove his Theory, which makes anyone capable of writing a Theory, without using any Facts whatsoever. Of course it's always advisable to throw a few facts around within the Theory, to add some Credibility to your Theory. Remember if you could prove a theory as Fact, then it would no longer be a Theory, but a Fact.
Seafloor spreading helped prove the theory of continental drift. Pangea theory also helped.
Newton explained his theory
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.
Einstein didn't prove the theory of relativity. It is a theory, a possible explanation, it is generally accepted because it explains a lot of things but that doesn't "prove" the theory, at least not to physicists. See related questions for the country of discovery.
