While it's a relatively new idea, the idea of the "Grand Tack" hypothesis http://en.wikipedia.org/wiki/Grand_Tack_Hypothesis as presented on this show is quickly becoming pretty main-stream, as it is the best idea yet that explains the distribution of the planets (rocky planets, gas giants, ice giants, and the asteroid belt and Kuiper Belt objects) that we see in our solar system toady.

I first came across the idea last year in a Coursera course "The Science of the Solar System" https://class.coursera.org/solarsystem-001 given by "Pluto-Killer" Mike Brown, and while it seems crazy that Jupiter went wandering around the inner Solar System in the first few million years, before the other planets had fully formed, it is actually pretty convincing.

I always keep an eye on SBS for their docos. I enjoyed it, found it very interesting.

Another headsup, Chris Hadfield is on One Plus One tonight, ABC, In case anyone is interested. I watched it this morning, nothing heavy.

yes saw it, turned it off after about 40 min. It was long on visuals, skating etc and short on ideas.

I caught it on on demand. thought it was alright and worth a look, interesting to see exoplanet discoveries helped to update solar system creation theories.
