Three thoughts come to mind when looking at this:
1) How amazing is it that we can detect neutrinos?
2) It makes sense why we have no experiments that can test string theory, since strings are orders of magnitude smaller than neutrinos.
3) Being able to visualize such huge objects in the finite space of a flash animation is what makes mathematics amazing. I’ve thought about doing a similar animation to this one, but with the Mandelbrot fractal in the background and zooming in past the Planck length; it doesn’t exist physically, but the fractal keeps going.
Note the scales are a bit different, so that the habitable zones of the Sun and of HD 40307 line up better (remember, HD 40307g is actually closer to its star than Earth is to the Sun – an AU is the distance of the Earth to the Sun, so HD 40307 is about AU from its star). What makes me smile is that the new planet is actually better situated in its "Goldilocks Zone" than Earth is! That’s good news, actually: the orbit may be elliptical (the shape can’t be determined from the types of observations made) but still stay entirely in the star’s habitable zone.
