Lup Quantum Gravity
i'm just a mathdeficient lay person, but it just seems to make sense. A smallest distance doesn't seem any different than discreet jumps in an electrons orbit or energy strings only vibrating in specified ways with nothing n between. The arguments for things like halography are robust enough that they should be true in any theory of quantum gravity. And this idea that you just put degrees of freedom at local positions in space is exactly not holographic. That's exactly not yo set up to be compatible with that fact about the gravitational universe. So maybe they just haven't gotten there yet.
