… if I would not be replying, he could not read this.  I am seriously 
considering to add you to my killfile, too, for repeated stupid behavior.
You have been warned.

FWIW, just a few remarks to show (you) how very wrong you are on all 
accounts.

Your conclusions are based on fals(ifi)e(d) premises.  /Ex falso quodlibet./
Experimental or observational evidence for them is missing, too.

Quanta are point-like virtual objects; they cannot expand.

The expansion of our universe does not really need a cause; we observe it, 
so we must accept it as a fact.

However, inflation theory, which has been most recently been supported by 
the observational results of the Planck Collaboration of 2015, posits that
the exponential expansion at the beginning was caused by an inflaton field. 

In any case, we are just witnessing the continuation of that initial 
expansion, not slowing down but accelerated again (observationally 
confirmed, Nobel Prize in Physics-awarded) by dark energy, the energy in 
empty space.

No, it is not.  Confirmed by experiments and working technical applications 
(including the computer that you are using to post nonsense here):

The speed of light is constant and the same for all observers in the same 
medium and in all directions (isotropic).  Confirmed by experiments, 
observations, and working technical applications (including the computer 
that you are using to post nonsense here).

No, it is due to the expansion of our universe (hence “cosmological”).  
Theoretically internally and externally consistent (GR), and observationally 
confirmed.

But *your* model does _not_ describe our universe – it has no relation to 
observed reality whatsoever.

Your half-wit guesses, which are expressed as pseudo-scientific word salad, 
among other gibberish, are hopeless.  Go away and study.
