​ but the trouble is the only thing that would have sufficient tensile
strength to build such a ring would be the degenerate matter that make up
Neutron Stars, and there would be 2 problems with using that:

1) A lump the size of a sugar cube would weigh as much as all 7.1 billion
people alive today on planet Earth ​put together.

2) It's only stable in a gravitational field 200 billion times as strong as
Earth's, at 1g a Niven Ring would produce an explosion that could be seen
from anywhere in the observable universe without a telescope or even
binoculars.
