You do not need academic or professional credentials to publish serious scientific papers. You just need to do careful meticulous work and come up with something unique or "new" in some sense.
It also works the other way. I have academic and professional credentials, but I'm not currently in a position to publish anything serious because I don't have the time, energy, and social networks. In order to publish something in a field that I've already worked in, it would take me about month to catch up, then three months to get some data, and then three more months of full time work, and it's hard because I'm not in a position to have co-authors.
Part of it is that there are no formal restrictions. You send the paper to ApJ, and that's it. The problem is that before I can publish something, it has to pass "internal peer review." I have to convince myself that it's worth publishing, because if it has my name on it, and I think it's garbage, then I'm going to be ashamed and embarrassed even if no one else cares.
It might be possible to "crowd-source" science, and one thing about Wikipedia is that you get a lot of professionals working on it because
1) there is no minimum time commitment. I've been using wikipedia for my work, and when I find an error, I fix it, and that takes five minutes.
2) anonymity helps a lot. One thing about having a professional paper is that before I sign something, I'd going to quadrulpe check it to make sure that I don't see anything stupidly embarrassing. On wikipedia, if I say something really dumb, someone fixes it and everyone forgets.
