Evolution News and Views noticed my previous post, and wrote a little reply. Unfortunately for them they completely missed the point, that Dembski claimed “Darwinists” were making stuff up, when there was good theoretical and (indirect) observational evidence to be confident that planets abounded in the galaxy.
Instead, they chose to focus on whether the planets we have found are habitable, which was beside the point . Guillermo Gonzalez wrote a response for them, which included this:
The typical exoplanetary system is very different from our Solar System. Jovian planets are being discovered in very tight or highly eccentric orbits. Jovian planets in our Solar System are characterized by large nearly circular orbits. Our Solar System looks ever more like the exception, and it is exceptional in ways that are life friendly.
Well, that’s sort of true, but deeply misleading. When we first started looking Super Jupiters were the norm. To explain why, and why this is no longer true, I’m going to digress for a moment to explain the main methods used to find exoplanets. The first is the radial velocity method. Here the slight wobbles produced in the position of a star by the gravitational tug of an orbiting planet are detected by Doppler shift.
In the transit method, the slight dimming in the stars light as the planet passes in front of it.
