Now, there are no voids. Any cubic volume of space at any time will have a measurable amount of mass or radiation (don't ask me how to measure it). Indeed, space itself may be related to energy in a similar way as mass is related to energy. After all, mass modifies space so it must be energetic.

To take that to a logical conclusion, even the thought of nothing, the existence of the concept, means there is something there. Therefore there is no void...in order for there to be such a condition there would even have to be an absence of nothing (as a conceptual entity).

This is true only from our present perspective. However, QM, Supersymmetry and String/M Theory would say otherwise. In these cases, the universe we see unfolded from a higher dimensional state, which whilst it may appear infinitesimally small from our perspective, is in fact many orders of magnitude larger than the universe we inhabit. Here space, energy and matter take on aspects which would be completely unfamiliar to us. Time itself would be something completely different, if it even exists at all.
