Thank you Peter. I am generally aware of modern proposed structure of atoms, electron probability waves/shells etc. The maths works, and so it must be that it represents something of reality. However I am not aware of the conversations which must have taken place, concerning implications for electron inertia. As electrons have mass, and how can a theory implicated with mass be disassociated with inertia? If this is so, then I would be very interested in the explanation, if it exists?

You have definitely given me pause, however I'm not completely over your side of the fence yet. Clearly I'm a little bias, but I'll try to keep that in check while I continue investigating. I know this must seam pretty silly to some

It could easily be true that the clouds disperse, however those images can be interpreted two ways. Take this image for example, which implies the clouds maybe collapsing, becoming denser at their center. cv.nrao.edu/~abridle/images/3c219lonopt_large.jpg Certainly not proof, but suggestive. And another very loose circumstantial case can be made concerning the quasar clouds are a very similar size to the defuse dust clouds that encapsulate many galaxies. But like I said, very circumstantial.

Thank you once again John. Yes I do refer to clouds ejected from Quasar jets. And you may be right, the clouds may simply disperse in space. Much of the dust referred to is in immediate proximity of galaxies, and their source theorized to be supernova and or stellar wind. But there are dust clouds further afield. These clouds are very diffuse, and I couldn't find reference to quasars being a source. But perhaps that's the simple truth. I would like to find visual evidence quasar clouds disperse. I'll alter my question
