Yep, that's a source of much of the boggling. The timescales involved too - there's a similar problem as there is with the spaces, *so* many orders of magnitude bigger than anything you can truly get your head around.
Nice little film, ta for the link.
They're definitely cheating when they sketch out the orbit of Neptune and say "and this is the edge of the solar system" though - sorry boys, you'll be needing a bigger patch of desert for that.
Thanks to you I've just been reading about the "Kuiper Cliff" - probably the most productive thing I've done so far today, at least I learned something.
For me I think the thing that best gets across the idea of the scale of the Solar System is the "Pale Blue Dot" photo.
