But those legs are only a few nanometers long!
Seriously, I wonder how this is related to Brane Theory. Could dark matter simply be graviational attraction for masses that exist in parallel universes? I have read that gravity may act in these extra dimensions and can be detected between adjacent universes.
Extra dimensions would give the brane-layers of space-time at least one degree of freedom to fold in. So yes, it could apply. Not that I would know a minkowski laminate from an affine vector-space.
