Three rings (planar circles) are "linked" together, but you'll notice that none is directly linked with another.

• The red ring is "behind" the yellow.
• The yellow ring is "behind" the blue.
• The blue ring is "behind" the red.

Still, while none is intertwined with another, it is impossible to pull them apart.

Is this a paradox?

Can this really be built?

The key words are "planar circles". Given that each circle is given to be on a plane, the only physical possiblity that such a formation could be built would require the 'bending' of space. As this is given as a possibility, though an extremely unlikely condition, it is not a paradox.
