Answer:
It can be changed by current evidence
Explanation:
A theory aims at explaining a phenomena. It is postulated on evidence and generally gives a generalized statement in the end. To establish a theory, it should be able to explain the observations. Although rare, a theory can be changed or discarded if new evidence suggests against it. A theory is made on current scientific findings and any new advancement can lead to new findings which do not support it. In this case, the theory can be changed or modified. A theory is accepted by everyone including the scientists.
