One of the cornerstone principles of science is the concept of falsifiability, that is for something to be called science it needs to be possible to prove the hypothesis to be false through observation and experiment. String Theory for example is a work in progress, with many predictions that cannot be tested due to lack of our technical capability. That said, experiments can be devised to validate or disprove those theories, it just may be that those experiments have not yet been funded or within our current capability. This is why String theory is not held up as a generally accepted model of physics, its just one possibility that is being explored. Many variants of String Theory have already been discarded as they predicted observations that are not seen (large numbers of magnetic monopoles for example), or contrary to observed fact (e.g. atoms could not form), hence they are falsifiable.
You have a lot to understand when it comes to the philosophy of science and what it means to conduct science. There are NOT "two groupings" of science, repeating the assertion does not make it so
