A more thorough explanation:

The bursting-bubble theory is the idea that a presumption or belief disappears once there is credible evidence that contradicts it. In other words, if there is evidence that proves a belief to be false, then that belief should no longer be held.

One example of the bursting-bubble theory is the belief that the earth is flat. For centuries, people believed that the earth was flat because it appeared that way to the naked eye. However, with the development of science and technology, we now have evidence that the earth is actually round. This evidence has burst the bubble of the belief that the earth is flat.

Another example is the belief that vaccines cause autism. This belief was based on a study that has since been discredited and contradicted by numerous other studies. The evidence that vaccines do not cause autism has burst the bubble of this belief.

These examples illustrate the bursting-bubble theory because they show how a belief or presumption can be proven false by credible evidence. Once this evidence is presented, the belief should no longer be held.
