A long story short - there are far too many clauses not clearly distinguished; whatever you're saying comes across as convoluted stoner-speak. In terms of the actual content, I'm not sure you're saying anything at all, it's all speculative words with no actual point, so far as I can make out.
I'm no physicist, but there's no clear indication what relationship these (ill-defined) 'clumps' have to the 'universal gravitational pull'
"the clumps are separating themselves
from each other with ever-increasing voids, the collective Universal gravitational pull would decrease ever
faster"
I'm not being terrifically helpful, but you're not being terrifical clear, capiche?
