So if you had a model of the Solar System in a park in Kansas, with the Sun 150 metres from your little half-inch Earth, you could place Alpha Centauri somewhere across the pacific in Japan (a sphere about 5.5 feet in diameter).

 

And the 'Earth-like' planet discovered today is 320 times the distance from us that Alpha Centauri is, so on this scale it would be 1.8 million miles away - more than 7 times the actual, real-life distance to the Moon.

How terrifying that the only way to conceptualize the vastness of cosmological scales is to utilized smaller, but still practically unimaginable cosmological examples.

Not only that, but in the other direction too.  A model of the atom is usually presented with a giant, sun-like nucleus surrounded by a cloud of moon-like electrons.  The proton is much more massive than the electron, but this difference is dwarfed by the diameter of the proton vs. the diameter of the entire atom.  IIRC, I saw an analogy something like: if the proton were the size of the sun, then the electron in a hydrogen atom would orbit it at about the distance of Uranus.  I hope I have that factoid correct.  Think how many suns you'd have to line up edge to edge to reach Uranus.  Then imagine cosmological distances from the perspective of a proton...

Yes but isn't it amazing that a species that lives on a marble, 150 metres from their Sun can know things about a slightly bigger marble, 1.8 million miles away?

Indeed.

If the movie Animal House taught me anything it's that there is infinite smallness as well as infinite space (bigness).   Deep.

..  a galaxy is known which is 13 billion light years away. The "Earth-like planet" is only 1400 light years away so it's actually a close neighbour in the big picture.

Nice film that gives you a feel for the scale of the solar system:

 

 

Strangely they had roughly the same idea as I described in this thread, except they built it in Nevada, not Kansas. The scale is quite similar (176m Earth-Sun rather than 150m).
