It's saying "maybe this is what's going on when things get smaller than the Planck length", well maybe it is and maybe it isn't. I saw no experiment or even a proposed experiment that could tell us. Perhaps someday Loop Quantum Gravity or String Theory will be able to make a testable prediction but they're not there yet so until then it's mathematics not physics. > Why are people so wedded to the traditional spacetime. > Because they're wedded to the scientific method. I asked before how you could perform an experiment without making use of space or time but received no answer.
