I'm kinda with Jeroen Vleggaa of Huygens Optics (on Youtube). These pure energy "virtual photons" "gravitons" etc are simply particles when they are measured, but are continuous wave disturbances in the underlying, non-quantum, field (meaning ethers). Light, for example, in the electromagnetic field cannot be seen until a quantum of energy is extracted to a mass particle (e.g., electron). Visible light, therefore, is a "virtual photon". And, in fact, is completely, always, completely invisible until electrons in your retina are excited enough to see it. Until you measure it with a particle that has mass.

There is no such thing as a photon or graviton in the underlying continuous fields. Calling them virtual photons or virtual gravitons is a bad analogy and a lie.

So the fields may well be continuous all the way to the "singularity" in the black hole. Just not your ability to measure it from outside the black hole. This might also say there is in fact no real singularity. Just a very continous fuzzyish one as the gravity field intensifies with more potential gravitational energy (like Einstein space-time curvature). The mass is still there and never goes to a point (violating Pauli exclusion) but the field energy is there. Just not as what we can measure as gravitons (from outside the black hole). As the quantum guys should have said, it ain't the observer, its' what the observer uses to observe. (In the basic human case, the atoms in neurons in his retinas).

I am not a physicists but aced all my courses in college before I decided the human brain, the perceiver of all this reality, is more important to understand. And we've made a lot of progress on that too since I graduated college in 1971.
