It says that spacetime exists as an interaction of gravity alone. This implies that there is no other frame of reference in this type of solution to GR. i.e. without mass there is no time in such a universe. Not a new idea.

And in contrast what would that make of you??
I'm saying that if there in some point in the future (because we can see it now) is sufficient mass density in the region of space of that big ring, and it is rotating, we tick every box we know of to theoretically allow for an eternal circle. "Engineering" it would mean that someone wanted some type of eternal existence, which is the profound idea at play here.
Engineering things without the technology to manufacture it happens all the time. Just because we can't imagine how to build it does not mean we can't calculate if it could exist.
