taken on a task that is impossible, by promising to compare notes, after all, is it possible to get R.L., the "educated" person to understand something that a three year old would grasp immediately?

OK let me put it this way: When I wrote the word "solid" I meant it in the "fundamental sense", that is, the density of the (what you call mass or energy) is so high that there is no "space" in the area. Space on the other hand is that "something" that you can stuff mass or energy into, such as the area between the nucleus and the electrons in the atoms or even the "space" between the neutrons and protons in the nucleus, or even the "space" that may exist inside the nuclear parts themselves. If there is a total lack of "space" in an area, then that area in my opinion is "solid".

If I understand the modern definition of the "black hole" correctly, it is supposed to be very high density "mass", therefore in my understanding it would be either totally "solid", or if it still has some "space" inside, then it could be considered as "almost solid". If the "black hole" is not "solid" in the "fundamental sense" then it can still "attract" or "absorb" more "conventional mass", but if it is "solid" in the "fundamental" sense, then it can not "absorb" anymore "mass" of any kind. When you say that: " mass, or an energy density, leads to a gravitational field" you are not explaining what "mass", "energy" or "gravity" IS; in effect, all you are saying is that, "this" or "that" leads to an observed effect.

So, WHY would "solid mass" attract mass of any kind? Would not a "empty hole" allow mass to "fall into it?

To clarify the fundamental meaning of the word "space"; in my opinion, "fundamental space" is any cubic area that is totally empty. If there is "anything" in that area, such as a photon or a "field" of any kind, then the area is not "empty". If a "field" or a photon exists in the cubic area, then that cubic area contains the "density" of that photon or field and is not "empty" anymore.

I could continue to explain how this relates to "gravity" , "mass", "fields" of all kinds, plus things such as the "end of the universe" and Einstein's relativity, but your attempts at "character deformation" have made me reconsider such an attempt.

Therefore "PLEASE try the cliff experiment" your self.

Have a good day.
