Ok. But I've kept up with physics- to some degree- over the years. It is news to me that Darwinism is closely related to the origins of the universe, galaxies, planetary systems etc. This connection, I would reckon, is pure speculation. Darwinism could be totally disproved and the Big Bang would still hold. Gravity, the Strong and Weak Forces- these things don't unravel if we lack Darwin.
I just fail to see any connection between a large planet orbiting a star nearby and how life may or may not have begun on this planet.
It's not speculation, it's a tool for visualizing a vast array of objects and conditions according to apparent complexity and organization. An organic rather than statistical approach to organizing our facts.
