I just stumbled upon Dino Kraspedon and his book "My Contact with Flying Saucers".
And if you read the chapter about anti-gravitation, I bet you will be quite amazed. Many explanations IMHO almost completely match Doctors cosmology.
Isn't that interesting?
His Book as PDF
EDIT: Maybe he peeked a bit in Dr's cosmogony before writing the book...
It looks like he used sometimes a quite similar cosmogony for explaining anti-gravity, but in the later part he switches quite strongly to a non Russellian cosmogony.
Well it's quite short, and I found it an amusing story...:bigsmile:
