I have no problem with research, but it's putting the cart before the horse to do something for a hundred years without having even shown it works, let alone explaining it mechanistically. You don't have to start medical school to start reading the research. And I'm refuting that your skull permits microsocopic movements of the type in question, and studies have shown there is very little reliability in people's ability to find such a rhythm:

If you start from a position that it has to be disproven, you're not doing science. The burden is on extraordinary claims to prove themselves.
Other studies have found no evidence to support it, and in one study, it was found to do harm. Here is another:

And another about the reliability of palpating craniosacral motion:

I don't have a PhD yet, but I'm scientist enough not to trust things that have not been proven. Appeal to authority does not work for me, and I don't give a crap about anecdotal evidence, no matter who it comes from.
No, they have, but there is often publication bias, as in, if the study does not prove your point, you don't publish it. I've seen this myself in certain alternative therapies (you don't want to be the practitioner discrediting your own practice). Things like homeopathy have shown no benefit through repeated meta-analysis.
Alternative medicine, by definition, does not work. If they worked, we would use it. More charitably, alternative medicines, by definition, have not been proven to work. We don't have to understand its mechanism to use it - hell, we still don't quite completely understand the mechanism of anesthesia drugs, but we use them all the time. It has to be proven
to work, not necessarily how for modern medicine to adopt it. If you can prove dianetics, cranial, or the flying spaghetti monsters can cure disease x or y, prove it, and it will be adopted by modern medicine.
