One thing that puzzles me about this concept (and string theory in general) is how a molecule is localized from the strings it is made of. And if strings are related to vortices from gravitons, how could the molecule move? When I move a pebble, all the molecules in the pebble move, which would mean that all the votices move. But that could not be possible if the vortices are caused by positrons that happen to be passing through that pebble on their way this this part of the galaxy.
