# Can postulates be proven wrong? [closed]

When Dalton gave his atomic theory, he postulated that atoms were the smallest indivisible part of matter. But now we know that they are composed of even smaller particles. So, the postulate has been proven wrong. Similarly, can other postulates like the postulates of Special Relativity be proven wrong?

• In science, we test theories' predictions against data, then realize something has to be rejected if they're wrong (although which postulate revisions are most helpful takes some trial & error). So far, relativity is doing well.
