scientifically possible, since not untrue
the way that scientists justify this kind of thinking is to call it theory.
All thinking, all theory, all theorizing, can be good.
The big question is to show HOW the thinking ("theory") has a practical use. All theory, big and small, has to be put to the test, over time, in different situations. It must do something good and useful for us, at some point, or else it will get discarded, like millions of other theories.
You could call it conjecture.
If it produces no tangible result, no difference in reality, is it "false"? No, it is just not yet proven one way or the other.
So... quacks can make stuff up, like a part A.) and a part B.) -- which is not necessarily false, but it seems to have no grounding in anything close to reality and practical use either. Until it produces a useful result it's just a lot of thinking, hooey, crap, and smoke that can confuse the willing-to-spend
Then, the quasi-scientist keeps on going for decades, fleecing lambs who are ready to be fleeced since they will let anyone with a theory sell them anything as long as the guy sounds like he knows what he is saying. Of course, the quasi-fraudman always sounds sincere, since he made the whole theory up himself and he knows it inside out. Unfortunately, it is not unlawful or illegal to sell people crap that they will swallow, and also not "crap with a theory to back it up" too.
If the theory backing it up can be proven positive and beneficial, it is no longer a scam sucking in the innocent. Unfortunately, billions of people have suffered from stuff wrapped in theories. Their money, and their health.
