"This problem exists only in your fantasy world, but in any case, what part of 'quantum effects overwhelm relativity in the early universe' didn't you understand?"- AntiGuv
Except, you don't even have Quantum Effects in such an early universe, just a "unified field." You've got to pretend that there is no Gravity, no independent Strong Force, no independent Weak Force, no independent electromagnetic force.
Then you've got to pretend that there is no Relativity (ooops, I mean, that relativity is "overwhelmed"). Then you've got to pretend that a "superdramatic" explosion hyper-accelerated Space, but not matter, vastly faster than C due to cooling that couldn't even happen prior to said explosion (because space hadn't expanded prior to said explosion event).
And that's just the Inflationary Era.
After that point, you've got to shift gears to pretend that the current ever-increasing rate of universal expansion is due to entirely different, though currently completely unknown (dark energy is a guess with no lab or physical support), processes.
You can make post after post about me being ignorant, arrogant, whatever, that still won't change the fact that the Big Bang Emperor has no clothes as itemized above.
As I've already noted, you are a confirmed obscurantist, and I haven't the slightest delusions about that. Try not to make the dreadful error of believing for even the most split trillionth of a second that I post anything for your benefit, since I do not consider you redeemable at all. Rather, I am posting for the lengthy list of people that you've inflicted yourself upon.
And, as my post above made clear, I am addressing one point and one point only: Your assertion that, if gravitational attraction of local systems counteracts cosmic expansion between bodies within that system, therefore inflation could not have taken place in the early universe due to gravitational attraction. That's it, and that's done.
Beyond that, feel free to 'shift gears' to whatever makes you happy, rhetorically crashing and burning all over the known universe. Whenever, if ever, I feel the need to jump into the fray on another topic you'll know it. Until then, have a nice day!
