Is the structural similarity between atoms ( smallest) and universe (biggest) a coincidence? Or there can a reason for this beyond imaginations?

It seems like, if one starts travelling out from atoms... and grows bigger and bigger, one ends in a similar structure somewhere in the universe. Kind of a circular ring.

PS: By structural similarity I mean : single nucleus and electrons revolving around in an atom, is structurally similar to planets revolving around the sun.

What is the structural similarity that you're referring to? –  Colin McFaul Nov 15 '12 at 15:02
single Nuclues and electrons revolving around in an Atom, is structurally similar to planets revolving around the sun. –  Vishwas Gagrani Nov 15 '12 at 15:52
Can there be a reason for this beyond imagination? ... I'm going to steal this line. –  Nikolaj K. Nov 15 '12 at 15:58
OP's question(v2) is perhaps indirectly spurred by the same $1/r^2$ dependence in the Coulomb electrostatic force and in the Newton gravitational force, cf. e.g. this and this Phys.SE post. –  Qmechanic Nov 16 '12 at 16:08
