You know in my humble opinion the energy it takes to travel between the stars is so great I think any reasonable civilization would rather invest in the home world and spend all that resource on their own star system rather than use it to go to another one. At least at the current technology level that we are at this seems to make sense.

Does anyone know where the system's planetary orbit plane would be? If it aligns with our sun, wouldn't a megastructure be plausible?

Has anyone see any monoliths around?

People are ignoring the possibility that this is a Shkadov engine instead of a Dyson sphere. If interstellar travel takes millennia, then no spacecraft is reasonable to get to another star system. Instead, you build lots of small solar sails hanging over one region of a star. They sit in equilibrium, not falling closer, not getting further out. This continuous mass on one side of the star begins to accelerate the star (very slowly) which pulls its planetary system along with it.

Now you are using your whole star system as your spacecraft, so taking a millennium to reach a new star system may no longer be a problem. You get to live comfortably on your home planet, while you move your whole star system where you want to go.

Last I knew, the Dyson sphere came first--Niven suggested it as an intermediate between spheres and planets.

He's actually here at World con, I could ask him.

You don't really want to make anything on that scale rigid. It's not anyway, at least when you look at the scale involved. Despite its thickness, when you look at the ratios it's rather thin and narrow.
