Dr Lissauer explained that the find challenges the notion that planets form by coalescing from discs of debris around young stars, bumping into each other violently in the later stages, casting them into irregular elliptical and out-of-plane orbits.
"I come from a planet formation theory perspective, and this has sent me back to the drawing board," he said.

Supports my suspicion that we are limited in our own understanding, by our own miniscule experience of the Solar System, and the physical processes observed here on Earth.
This still does not support the idea that 'life MUST be out there', however, it does support the concept of: 'infinite diversity through infinite combinations'.
If this ever turns out to become an emerging consensus picture, then the view that a specific occurrence of life emerging, actually
requires a universe of the size and dimensions of our observable domain, would seem to become even more credible than it presently is.
