"Planet formation is a story with a well-known beginning and end, but how its middle plays out has been an enigma to scientists-until now."
Notice the confidence of the first sentence. They use words like "well-known" and imply they have all the answers "now".
But as the article goes on, down past what the headline reader is willing to read you find that they lose confidence.
Although Mac Low and his colleagues kept planet-forming boulders safe from the gravitational clutches of stars in their simulation, he noted that many questions remain."
You find that "many questions remain" which I am sure is true and I don't slight them for that but it continues.
"There are enough uncertainties that [planet formation] is not going to be an open and shut case any time soon," he said. "We don't know how that collapse into a planet actually occurs.
The title of the article uses the word "solved" a definite answer but now we see how little is solved. Now we here of "uncertainties" and that its not an "open and shut case" and the dreaded "we don't know".
This does not deter them and their "confidence" in their "theory", they "think".
"Despite the problem, Mac Low is confident the theory will hold up to future scrutiny."
"All that material is gravitationally bound together, so we think it's likely that it will form large objects," he said."
Here is their greatest evidence.
"Overall, the calculations present an encouraging approach to understanding how something happened that we know must have happened, at least for the terrestrial planets,"
It must have happened!
Words of a solved mystery.
"One idea, thinks, we don't know how, despite the problem, the theory. we think it's likely and we know must have happened."
Here is their answer.
In the beginning God created the heaven and the earth.
