The aether reference is new to me Phractality? If you assume something not grainy but smooth without 'chinks' that you can magnify over and over without ever finding it becoming grainy, would that be a aether?
And another thing I'm wondering about. What is the center of a Black Hole consisting of? Energy? What defines the constriction holding that energy. To create a gravity you will need some way of 'trapping' that 'primeval energy' methinks? And somehow those questions belong together in my mind.
The planck length is not definitive for this reason. The speed that light travels resolves to 1 planck length in 1 planck time. As nothing else can travel at light speed then other particles must move at a fraction of a planck length during 1 planck time interval.

If the universe is truly grainy at the smallest scale then the logic doesn't work really - if we are postulating an entire new idea then you get to make provisions for that sort of hitch.I don't instinctively agree with quantum foaminess / small scale granularity - but for those that do; to get around your problem one could simply postulate that all matter crosses planck length grains in the planck time but that matter is delayed at boundaries/limits of each grain whereas radiation is not delayed at boundary. ie there is a border transition time for mass that is zero for luxons.
