Here we are, back to scientists describing the Aether that isn't an Aether.
"...empty space isn't really empty, but instead populated with 'virtual particles.' These particles are artifacts of the fact, described by quantum mechanics, that physics is governed more by probabilities than fixed realities. Because of the small possibility that a particle might exist in any one empty point in space, that empty point in space acts as if the particle is sort of, kind of there. And those virtual particles have real effects on the world."
Since when does a mathematical probability function become a physical fact in the real Universe? What the scientists are not saying, and which the real facts allude, is that there is a very real, non-material structure to the fabric of space. Space is not a physical substance, like matter, but rather a non-material structure that gives rise to magnetic fields, electrostatic fields, and gravitational fields (all of which are non-material realities). Even the spin property of subatomic particles, and the speed limit of light are functions of the space the subatomic particles reside in.
What the scientists are close to discovering is that black holes are not physical objects such as the much touted super massive black holes, but rather black holes are regions near the centers of galaxies where the structure of space collapses, and visible matter is converted to dark matter. And yes, space can become (and is) polarized in such a way as to prevent the entire galaxy from unraveling.
