In loop quantum gravity, links that make up the loops stitching together the quanta volumes of spacetime, in effect, create ordinary spacetime. They are usually local, that is, they are causally related. But not always. It is possible that a link between nodes of volume could have been established early in the history of the universe, and then they separated. Somewhere across the universe, then, could be an entangled quanta of volume corresponding to a local quanta of volume.
The Spin-Two drive makes use of these non-local links for almost instantaneous transport between widely separated regions of spacetime. However, it is possible to overuse these links, which results in an effect similar to a sinkhole in the ground. The link network which under girds spacetime becomes very haphazard instead of regular and can create areas where mass itself dissolves as if sinking into the abyss. Eventually, these areas become a form of Anti-de Sitter (AdS) space, which can spread, and while it is a solution to Einstein's equations, AdS is not a solution that can support life.
