IANAP but if I understand TFA correctly, then they propose that the possibly detected graininess of reality is the result of the ratio between the surface area of our lightcone (the boundary from beyond which light has not had time to reach us in the 13.7-billion-year lifespan of the universe) to it's volume.
Does this mean that we are getting grainier over time, since the radius of our lightcone increases with lightspeed?
