Thanks for the detailed reply, IP. I think our disagreement may be primarily a semantic one, but there may be a little substance here as well. Now that I think of it, if you're replying to redcoat, you may have the properties of a proper scientific explanation in mind, whereas I was interpreting matters more broadly. The practice and body of science is more than just explanation, if you look at it closely enough, though explanation may be its ultimate goal.
Wouldn't surprise me at all.
My native language is Spanish. Besides the fact that, naturally, I find English to be quite challenging (especially when I'm trying to explain something I've learned in a different language), I have found, through painful experience, that often we either use the same word to name opposite things/processes, or use opposite words to name the same thing (don't tell anybody, but I'm sure it's a conspiracy orchestrated to impede me to function properly on Internet forums...

)
My point is this: all that separates anybody from publishing a "study" on the Internet is the knowledge on how to use Adobe Acrobat.
A few years ago, in another forum, a member cited a study, signed by a scientist at an American University (I don't really remember which one), explaining the reasons why ethanol wasn't a suitable alternative fuel to gasoline. Being that biofuels have been kind of an obsession of mine for a long time, I took the time to fully read the study (about 90 pages, give or take). Upon reading it, I couldn't believe somebody with a minimal knowledge of physics or chemistry had written such a piece of garbage.
So I went to the university's website, only to find out the guy really was part of the staff, BUT HE WAS AN ENTOMOLOGIST!!!
A couple of months later, I went looking for the "study", and it wasn't there anymore.
All these other studies about cell phones, or beer, causing cancer, or about onions promoting hair growth, are nothing new. They pop up like roaches every time you kick a stone. Yet people still buy them.
But enough ranting.
Going back on topic, yes, if you take certainty as the absolute lack of doubt, evidently it's impossible. Some would even argue it's undesirable.
I was taught that, from a scientific point of view, certainty is more like the "beyond any reasonable doubt" statement used in law. Something that makes a scientific statement, irrefutable
as of now.
You may also be right on (4.). For the last couple of hours, while I was locked out of here (damn 404 error...

), I've been reading about science, and other stuff, and found out, for example, that there seems to be a different definition in English for things like "law" (scientific) or "theory", than what I was taught in Spanish.
In a nutshell, I was taught a theory is an idea that hasn't been scientifically proven, while a law is a theory,
after it was proven. For what I read, things are quite different here.
Oh well...Looks like I'm gonna have to hit the books again...
