In mathematical physics, the concept of quantum spacetime is a generalization of the usual concept of spacetime in which some variables that ordinarily commute are assumed not to commute and form a different Lie algebra.The choice of that algebra still varies from theory to theory. As a result of this change some variables that are usually continuous may become discrete.

“I think it might help us move towards a theory of quantum gravity,” said Lucien Hardy. reconstructionists suspect that we’ll find it only by rebuilding quantum theory from scratch: by tearing up.

So we already know something about a quantum theory of gravity, before we ever try and formulate one! We know this because whatever the true quantum theory of gravity turns out to be, it must be.

So I think we should be open-minded about the possibility that some fundamental truths about nature could be too complex for unaided human brains ever to fully grasp. For instance, any unification.

The full version of the duality is a conjecture, but it has a well-understood limiting case that string theory plays no role in. Because strings don’t matter in this limiting case, it should be shared.
