There otta be a law that every article like this declares just like the writing on a cigarette pack that the findings of the authors are their best guesses based on the knowledge at hand and that it is just a good damn guess. There will be a new idea somewhere down the road that turns this "knowledge" into trash. That you can count on.

Care to prove global warming anyone?

My favorite junk phrase from the pop-science publishing crowd: "We now know."

It's used this way: "At one time, people believed that [insert old theory here]. We now know that [insert new theory here]."

Makes you wonder, what are we going to "know" tomorrow that will change what we "now know" into what we "once believed"?

Well, friend, it is assumed that science progresses from best guesses based on knowledge at hand, being as to how that is the way it works. Luckily, science does not claim to be ungrounded 'found' knowledge such as one discovers in religious myth. Were it to be a priori, there wouldn't be anything left to learn, since all is known.
