I've heard of it. I have no idea how it could possibly be tied to the rotation of the Earth.
There are a lot of possible explanations. Coincidence is entirely possible, as is different laws of physics holding on huge scales (like how quantim physics only hold on small). Plus it would be explained by the existence of other universes: a point where ours 'collided' with another.
Link.
The only place I can see any mention of Copernicus would be
here, and it's little more than a coincidence of shape. Skip to the end for the mention: the idea is that part of the structure resembles the orbit of the Earth around the Sun. That's probably meaningless: with all the map and all the things any aspect of it could show, mixed in with all the areas of science something like that would be possible...
However, if it is meaningful, it could only be so if the Earth does indeed rotate. Krauss mentions, light-heartedly, that this would make the Earth the
figurative centre of the universe. You might have seen and misinterpreted the quote.
