Some theories are considered true - others we are pretty sure are not are not true.
A theory is merely a testable hypothesis - an educated guess if you will. We are constantly revising and modifying theories based on new information and the results of tests of the theories.
If a theory is found to successfully predict or correlate with observations over a prolonged period of time it generally gets elevated to being considered a "law" - but even "scientific laws are fair game for modification - or being discarded - if a counter example is found or a a new theory more successfully predicts and explains what the law was trying to account for.
