What may happen when scientists make new observations that seem to show that a theory is wrong?

Sometimes a theory is set aside by scientists, because there is no way to examine its assertions analytically; these may continue on in the popular imagination until some means of examination is found which either refutes or lends credence to the theory. It then can be further studied. It then goes back to becoming a hypothesis until it is again scientifically proven to be true.
