Fabric of space-time
The FABRIC OF SPACE-TIME is the fabric that holds the fundamental Über-Stuff of the Space-Time Continuum together. It is different from cluons and duct tape which are more akin to adhesives than fabric. All of the foregoing are vital to the functioning of the Space-Time Continuum. It's usually very solid, almost like cotton, but like any fabric it tears on occassion. When it tears, really, really bad things like John Steinbeck and the movie Seven Years in Tibet happen. No one fully understands it yet, but scientists claim they have rooms of monkeys working laboriously to solve the mysteries that space-time holds.
