Any theory can be disproven. A theory is simply a hypothesis that has been accepted as generally true, however in the realm of science, anything can be disproven.
A scientific theory is just an educated guess related to natural observation. A theory can never be proved wrong, it can only be stated as “disproven” as there were not sufficient evidences to prove it right. For example – Lets assume a scientific theory that “every night after sleeping , monkeys come and eat the remaining food” now evidences will be required to proved this theory as correct. But in most of the cases the researcher do not get sufficient evidences and thus the theory is disproven with a scope that it can be proven right at any instance of time when sufficient proofs will be available.
